서울시 공공 WIFI를 대상으로 개인정보취득이 불가능한 무료통신망의 품질 향상 방안

임동현,박대우 한국통신학회 2024 韓國通信學會論文誌 Vol.49 No.1

Free networks(WIFI, LoRa, UWB, BT, Beacon etc.) are networks that are not managed by telecommunications carriers and are managed by a smaller budget and fewer engineers than commercial networks(LTE, 5G etc.). Unlike commercial communication networks, free communication networks cannot obtain network status information from individual terminals, which limits quality improvement. In this study, we investigate how to manage a high-quality network in a free communication network without obtaining consent to use personal information, i.e., personal terminal status information, which is a characteristic of free communication networks, using the case of public WIFI in Seoul. For this purpose, a tracker in the form of an Android-based or dedicated device is mounted on a vehicle or carried by a specific person, such as a maintenance worker, to move around the city and monitor the network status from a loopback perspective. The results measured by these terminals are the service connection information available in the location, and the data is periodically transmitted to the public WIFI operation center. By spatially analyzing them in GIS, it is possible to check the actual serviceable area, check the network but not the serviceable AP, and monitor unregistered APs and security threat APs to improve the communication quality of the free communication network. If the results of this paper are applied to urban centers such as Seoul, it will be possible to effectively operate the free communication network, which is the basic infrastructure of urban networks, and realize an advanced smart city.

프랑스 방통융합법제와 그 시사점

박균성(Park Kyun-Seong) 서울대학교 공익산업법센터 2008 경제규제와 법 Vol.1 No.1

In France, broadcasting and communication have traditionally been separately regulated, and broadcasting-communication convergence has been regulated by Act on Internet Broadcasting and Broadcasting Services on July 9,2004 (Act No. 2004-669). The legal systems on broadcasting-communication convergence in France have following characteristics: 1) Problems arising from broadcasting-communication convergence has been settled by setting up technological and organic relations between broadcasting and communication, while retaining peculiarity in each realm. 2) Regulatory authorities are different from policy-making authorities. Basically, policies are made by administrative authorities, and independent regulatory authorities are in charge of regulation. Nevertheless, systems are provided for collaboration in policy-making or regulation between such administrative authorities and independent regulatory authorities. 3) Regulatory authorities are independent form the government, and are divided into general regulatory authorities and special regulatory authorities. 4) Following broadcasting-communication convergence, the term, ‘electronic communication’ has emerged from such existing terms as ‘broadcasting’ and ‘communication’. 5) Regulation on network is separated from regulation on contents. The Broadcasting Committee regulates broadcasting programs that air through internet. Nevertheless, the Broadcasting Committee does not have control over contents that are not broadcasting programs (for instance, VOD). On the other hand, the Office of Postal Services and Communication regulates not only communication networks, but also broadcasting networks. 6) Prior to the legislation of Electronic Communication Act in 2004, electronic network business runners and service providers used to need approval from the relevant Minister, however they just need to report their businesses to the Office of Postal Services and Communication, according to this Act.

보드리야르의 의사소통이론에 관한 연구

배영달 한국프랑스학회 2013 한국프랑스학논집 Vol.82 No.-

Aujourd'hui notre société déborde d'écrans et de réseaux. Selon Baudrillard, notre quotidien se connecte à l'écran et ‘nous sommes écran dans une certaine mesure’. Nous sommes dans la sphère d'écran, et nous avons tendance à nous y absorber complètement. Par exemple, nous ne décidons pas en conscience de regarder la télévision. Nous le faisons par une sorte d'attraction, de vertige. On a l'idée que la machinerie d'écran n'a pas pour dimension réelle l'information et la communication. Tout ce qui nous est offert par les nouvelles technologies, c'est l'image d'écran où l'on s'y immerge. C'est-à-dire que nous circulons à travers l'image d'écran, et que nous nous perdons dans l'extase de la communication. Alors, la théorie de la communication de Baudrillard peut s'appliquer en quelque mesure au monde de ‘SNS’(Social Network Service)? L'immense SNS de ‘Facebook’ et de ‘Twitter’ facilite la communication par ‘Smart phone’ et internet. Facebook permet les relations réciproques entre les hommes, et ‘Smart télévision’ a la fonction d'interaction. Mais on peut qualifier la relation humaine par SNS de la vraie communication? Comme Baudrillard l'a indiqué, la communication d'excès n'apporte pas plutôt l'absence de la communication ou l'extase de la communication?Ces jours-ci, il semble que l'expression de race de ‘Smart Island’ réflète un peu l'opinion de Baudrillard. On se connecte mais réellement on se déconnecte. Ce phénomène a rapport profondément à notre vie sociale. Si notre téléphone mobile se déconnecte, nous nous sentirons isolés de la société. Il est évident que SNS permettant de se communiquer doit être la grande technologie de la communication. Mais SNS forme tantôt la communication réciproque, tantôt l'unilatéralité de l'échange communicatif. En particulier l'expansion de fausses informations par SNS apporte la non-communication ou la communication unilatérale. Baudrillard a dit que le médium lui-même est la mode de la non- communication ou de la communication unilatérale. Cette position de Baudrillard a eu la persuasion avant l'apparition de SNS, mais il semble qu'elle a sa limite qui s'applique partiellement à l'époque de SNS. Mais son insistance que l'interaction de l'homme communicatif est devenue celle d'écran. et que l'incertitude de la communication vient de l'excès de réseau de la communication peut être une référence pour la compréhension de médium et de communication d'aujourd'hui.

Not All Communication is Created Equal

Social networking service (SNS) has unique characteristics that distinguish it from traditional communication environments. Primarily, SNS enables a fundamentally different ecosystem for communicating marketing activities. Incidentally, the communication paradigm has shifted online today, and a social media marketing strategy allows integrating bi-directional communication into the marketing process. This research attempts to identify an effective communication strategy to facilitate social media marketing using a combination of communication facets such as frequency, direction, formality, and content. In addition, the study demonstrates how perceived communication quality influences consumers’ attitude toward a corporate brand and e-WOM intentions. To achieve these objectives, we conducted two experiments: the first investigates the interactive effect of frequency (frequent vs. infrequent) and direction (uni-directional vs. bi-directional) of communication; the second examines the interactive effect of formality (formal vs. informal) and content (direct vs. indirect) of communication. Experiment 1 shows that in bi-directional communication, the frequency level of communication does not matter in perceptions of communication quality. However, if the direction of communication is uni-directional, frequent communications make consumers experience stronger perceptions of communication quality than infrequent communication. Experiment 2 demonstrates that among the combinations of formality and content of communication, informal and indirect communication is effective in increasing perceptions of communication quality. By integrating the results, the research concludes that bi-directional communication through informal modes, with indirect content is the effective communication strategy for social media marketing. This study extends the scope of social networking service (SNS) research in communication, and opens new research avenues for effective communication strategy on SNS. The study also provides valuable and applicable implications for corporate social media marketing activities.

Social Network Service의 Visual Communication 표현 유형별 특성에 관한 연구

이영미 ( Young Mi Lee ) 한국기초조형학회 2012 기초조형학연구 Vol.13 No.4

첨단 테크놀로지의 산물인 Social Network Service는 사용자의 니드에 부응하여 무한대로 확장되고 있다. 확장과정에서 주된 커뮤니케이션 기능인 문자언어는 커뮤니케이션이 용이하고 범용성이 풍부한 그래픽 언어로 대체되면서 SNS에서 디자인 영역의 연구는 필수적이 되었다. 본 연구는 디지털미디어의 새로운 환경인 소셜 네트워크를 통한 소셜 미디어의 특징과 SNS의 Visual Communication 표현유형 사례연구를 위해 다양한 기종의 스마트폰에서 가장 대중적으로 인기 있는 대표 SNS인 카카오톡을 중심으로 연구하였다. SNS Visual Communication의 표현유형 중에서 가장 대표적인 이모티콘은 복잡한 문장을 단순화된 아이콘으로 디자인하여 가장 쉽고 빠르게 커뮤니케이션 할 수 있다는 특징을 가지고 있다. 앞으로 SNS의 인터페이스 환경 및 운영체계가 더욱 다양화 될 수 있지만, 커뮤니케이션에서는 문자 중심보다는 Visual Communication의 시각적 표현방법이 더 활발히 이루어질 것이며 감성적 표현도구인 활자에서 이미지화로 이모티콘에서 이미지, 사진 그리고 음악 등좀 더 다양한 모션이 강화된 새로운 형태의 표현 유형이 등장하게 될 것으로 본다. 본 연구에서는 Visual Communication의 표현유형을 형식성, 정확성, 적시성을 감안하여 논의하고 시각적 표현의 적정성 여부는 제어도, 집중도, 흥미도를 감안하여 평가하였다. 연구결과 첫째, 핵심메시지 내용의 다양한 무빙표현이 더욱 확대되어야 할 것이며, 둘째, 보다 단순한 표현으로 메시지 집중도를 높이는 게 바람직 한 것으로 나타났다. As a product of high-technology, Social Network Service(SNS) has been expanded to infinity corresponding to the need of users. In the expansion process, written language as a primary communication function has been replaced by graphic language, with which communication was easier and more widely used, thus making research on SNS design area essential. This study investigated the characteristics of social media through social network, a new environment of digital media. The study also focused on KakaoTalk, one of the most popular and representative SNSs, among various models of smart phones for a case study of the expression types of SNS visual communication. The most typical emoticons of SNS visual communication by expression type had the characteristics that one could communicate more easily and quickly with design a complex sentence using simplified icons. The interface environments and operation systems of SNS may become more diversified in the future, but the expression method of visual communication will be more active than letter-based communication. In addition, it is expected that there will be new forms of expression types intensified with various motions and the change from emoticons to images, photos and music. This study examined the expression types of visual communication from a consideration of formality, accuracy, and timeliness and the appropriateness of visual expressions in terms of the degree of control, concentration and interest. The results were as below. First, various motion expressions of core message contents should be further expanded. Second, it will be desirable to enhance the degree of concentration in messages through more simplified expressions.

정보통신망 침입행위 관련 연구 - 정보통신망법 제48조 제1항을 중심으로 -

전응준 ( Eungjun Jeon ),신동환 ( Donghwan Shin ) 중앙대학교 법학연구원 문화.미디어.엔터테인먼트법연구소 2020 문화.미디어.엔터테인먼트 법 Vol.14 No.1

정보통신망법 제 48 조 제 1 항은 ‘정보통신망’이라는 추상적, 포괄적, 유동적인 개념을 객체로 하고 있다. 정보통신 기술과 인터넷의 발달로 전 세계가 사실상 하나의 정보통신 네트워크(망)로 연결되어 있다고 볼 수 있다. 주어진 상황과 논의의 배경에 따라서는 전 세계적인 정보통신망 하위에 다양한 계층과 범위의 무수히 많은 정보통신망의 개념이 정의될 수 있다. 이러한 추상적, 포괄적, 유동적인 개념인 정보통신망에, ‘정당한’, ‘접근권한’이라는 규범적 요소들과 ‘침입’이라는 행위태양이 더해짐으로 인해 정보통신망법 제 48 조 제 1 항이 금지하는 침해 행위의 범위가 무한히 확장될 수 있는 위험이 있다. 본고에서는 정보통신망법 제 48 조 제 1 항의 입법연혁과 규정의 내용 그리고 보호법익을 살피고 이를 미국, 유럽연합, 일본, 독일의 유사 법제와 비교법적으로 고찰한 후, 그와 같은 검토 결과 및 대법원 판결례에 기초하여 정보통신망법 제 48 조 제 1 항 각 구성요건의 의미 내지 범위에 대한 해석론을 제시한다. 정보통신망침입의 객체가 되는 정보통신망에는 ‘정보통신체제’를 이루는 정보, 기능, 기기(하드웨어), 기술(소프트웨어) 또는 서비스 등은 모두 포섭될 수 있다. 또한, 구체적으로 어떤 구성에 대한 접근이 정보통신망 침입에 해당하는지 여부는 해당 구성에 접근한 경로 내지 경위, 그 구체적인 행위태양, 그리고 접근에 따른 결과 등을 종합적으로 고려하여 해당 접근으로 인해 “정보통신망 자체의 안정성과 그 정보의 신뢰성 보호”라는 보호법익이 침해되었는지 여부를 기준으로 판단해야 한다. 만약, 이러한 보호법익을 고려하지 않는 경우, 구성요건의 불명확성으로 인해 범죄의 범위가 과다하게 넓어져 죄형법정주의에 위반될 여지가 있다. Article 48 (1) of the information and communications network ACT is based on the abstract, comprehensive, and fluid concept of the “Information and Communication Network”. With the development of information and communication technology and the Internet, it can be said that the world is virtually connected to one information and communication network. Depending on the given situation and the background of the discussion, various concept of information and communication networks of various layers and ranges can be defined under the global information and communication networks. By adding the normative elements such as 'rightful' and 'access authority' and the mode of action called 'trespass' to this abstract, comprehensive, and fluid concept of information and communication networks, there is a risk that the range can be expanded indefinitely. In this paper, we examine the contents of the legislative history, regulations and benefit and protection of the law of Article 48 (1) of the Information and Communications Network ACT, and examine them in a comparative manner with similar legislation in the United States, the European Union, Japan, and Germany. On the basis of this, an interpretation theory for the meaning or scope of each component of Article 48 (1) of the Information and Communication Network Act is presented. Information, functions, devices(hardware), technology(software), or services constituting an 'information communication system' may be all included in the information communication network that is an object of the information communication network trespass. In addition, whether an access to a certain configuration constitutes the trespass of the information and communication network depends on the approach or the route of access to the configuration, its specific behavior, and the results of the access. And also it should be judged on the basis of whether benefit and protection of the law such as “the protection of its own stability and the reliability of its information” have been violated. If this benefit and protection of the law is not taken into account, the scope of the crime is excessively widened due to the uncertainty of the compositional requirements, and there is a possibility of violating the principle of "nulla poena sine lege".

의사소통행위이론에 따른 디지털 네트워크의 커뮤니케이션 전략에 대한 연구

장우린(Chang, Woo Rin) 한국디자인문화학회 2015 한국디자인문화학회지 Vol.21 No.4

후기구조주의가 대중들에게 생산한 포스트모더니즘은 그 상대성으로 말미암아 주체와 타자간의 이성적 의사소통에 대하여 회의적일 수밖에 없었다. 하지만 디지털 네트워크화 된 시대를 사는 우리들에게는 타자들과의 복합적 대화의 관계망에 위치하면서 소통의 요구에 늘 직면하게 된다. 이제 다시금 대화하는 주체와 이해 가능한 타인에 대한 규정이 필요해진 것이다. ‘체계’에 의한 중재 자체가 목적이 아닌, 타인에 대한 이해가 목적이 되는 하버마스의 의사소통행위이론은 후기구조주의적 상대성과 후기자본주의의 파편화된 대화 모두를 비판한다. 이를 통해 후기구조주의를 거치며 플라톤과 데카르트로부터 절대적 지위를 부여 받은 이 이성적 주체는 이제 반성적 주체로 다시 태어나게 되었다. 이제 이 주체는 생활세계에 기반한 의사소통행위로부터 디지털 네트워크 속에서 자정작용을 갖는 건강한 유기체로 거듭날 수 있다. 하버마스는 이 지점에서 긍정적 가능성을 던지고 있는 것이다. 후기구조주의의 시대를 거쳐 비판적 해석학으로 새롭게 주체를 부활시키는 하버마스의 의사소통행위이론을 살펴보면서, 디지털 테크놀로지의 이론적 대변자로까지 일컬어지기까지 했던 후기구조주의의 대표자 푸코를 뛰어넘어, 하버마스로부터 이제 소통할 수 있게 된 창조적 주체를 발견할 수 있다. 이것은 본 연구의 방법론이기도 하다. 디지털 노마디즘은 이제 대화와 소통의 관계망 속에서 디지털 커뮤니케이션이 되는 것이다. 후기구조주의에서도 우리는 체계에 대한 거부를 목격한다. 그러나 그 회의 이후 우리는 어떤 추구에 대하여도 항상 회의적일 수밖에 없게 되었으며, 그러므로 후기구조주의는 보수적인 성향을 갖게 된다. 하지만 하버마스는 이해와 소통의 조건으로서, 즉 의사소통행위의 가능조건으로서 "생활세계"를 지향하며 "체계"를 거부한다. 이해와 소통을 궁극적 목적으로 하는 이러한 적극적인 소통행위는 체계로부터 자유 하는 주체, 즉 하버마스가 주장하는 생활세계 속의 주체를 필요로 한다. 이 주체의 긍정적이고 적극적인 지향이 본 연구에서 디지털네트워크에 대한 의사소통행위 전략들을 수립하게 만들었다. 이 전략들의 요지는 첫째, 생활세계를 지향할 것, 둘째, 이해는 언어적 발화로부터만 기인할 것, 셋째, 텍스트 자체만을 대상으로 삼을 것, 넷째, 이해 목표가 설정될 것, 다섯째, 자정작용이 작동할 것, 여섯째, 객관세계로 이끄는 촉매역할을 할 것, 일곱째, 삶을 통해 실천될 것으로 정리된다. 이러한 입장은 소통을 위해 스스로 겸비하는 겸손한 주체, 늘 타인에게 귀 기울이는 주체의 원형을 마름질해 낸다. 한때 절대 이성의 소유자였던 주체는 후기구조주의를 통해 그 이념적 고착을 자각하고 진실하게 소통하려는 주체로서 하버마스에까지 이르렀다. 그리고 이러한 반성적 주체는 우리로 하여금 디지털 네트워크가 새로운 소통과 이해의 공간이 될 수 있음을 다시 꿈꾸게 하는 것이다. The postmodernism produced by the poststructuralism, it is skeptical about the communication between subjects and others, but living in a digitally networked world we are not possible to avoid the communication with the others, in the network which has a complex and massive interactivity; now again we need to have the definition of the others who could communicate with ourselves. Not a purpose to arbitrate by the System but to understand the others, Habermas’ Theory of Communicative Action criticize the relativity of poststructuralism and the partial communication of postcapitalism, so the reborn has been accomplished: the rational subject has become self-reflecting one. And so on, this subject could become a complete organism which has a self-purification due to Communicative Action based on Lifeworld; here is Habermas" positive point of view. Researching Theory of Communicative Action which resurrects a new subject using a critical hermeneutic through out the period of poststructuralism, and then overcoming Foucault who was considered the academic voice of digital technology, we could discover up the creative subject who is sufficient to communicate with the others; it is also the main method of this research. Digital Nomadism becomes Digital Communication in the network of Communication Action, at last. In the field of poststructuralism, we could observe a strong rejection against System, but after this rejection, it is inevitable for us to be negative in front of all kind of pursuit, and therefore the poststructuralism takes a ply of being conservative. Meanwhile Habermas denies System for permit Lifeworld as a condition for potentiality of Communication Action. This Communication Action which tends to "communicate actively" needs to bring the liberal subject in Lifeworld: the term of Habermas. This positive and aggressive pursuit has produced the strategies about Communication Action in the field of digital network. Here are the essentials of these strategies: (1) Pursuit of Lifeworld, (2) Understanding coming from Speech Act, (3) Only the Text as Target, (4) Setting up a Goal for Understanding, (5) Activating the Self-purification, (6) Catalysis toward Objectivity, (7) Practice in Life. This kind of stand point allows to produce a prototype of subject which has a modesty to communicate and to listen always carefully to the others. The subject which had once a absolute rationality has arrived at Habermas, as one who has realized his ideological attachment and who is eager for sincere communication, and this existence of self-reflecting subject makes us dream of this: the digital network is capable to be a new space of communication.

커뮤니케이션 네트워크에서 불확실성이 집단응집력에 미치는 영향

허남일,이성철 한국기업경영학회 2010 기업경영연구 Vol.17 No.1

The purpose of this study was to investigate the effects of communication networks on group cohesiveness under situation of uncertainty in four-person groups. The communication networks were divided into wheel, circle and concom according to centrality. The uncertainty was manipulated by varying stimulus ambiguity. The group cohesiveness produced significant difference among three networks. The higher group cohesiveness was presented in the order of concom, circle and wheel network. The communication networks were classified into two classes according to relative centrality. The wheel network was classified into centralization network, whereas the circle and concom network were classified into decentralization network. The group cohesiveness did not produced significant difference between circle and concom. But there was significant difference in terms of group cohesiveness between centralization network and decentralization network. That is, the decentralizatin network was related with higher group cohesiveness than the centralization network. The communication networks affected differently on group cohesiveness according to the degree of uncertainty. The higher group cohesiveness was presented in the order of wheel, circle, and concom under certainty situation, whereas it was in the order of concom, circle and wheel under uncertainty situation. The group cohesiveness did not show significant difference between circle network and concom network according to the degree of uncertainty. But the group cohesiveness showed significant difference between centralization network and decentralization network according to the degree of uncertainty. That is, the centralization network showed higher cohesiveness than decentralization network under certainty situation, whereas the decentralization network showed higher cohesiveness than centralization network under uncertainty situation. As a result, the uncertainty affected group cohesiveness in communication network. The decentralized communication network is more effective than centralized communication network under uncertainty. The interaction effect of uncertainty and communication networks on group cohesiveness can be explained by uncertainty reduction theory. 본 연구에서는 의사소통을 하는 과정에서 커뮤니케이션 네트워크가 집단응집력에 어떤 영향을 미치는지를 알아보고자 하였다. 본 연구에서는 네트워크의 집중도에 따라 바퀴형, 원형, 완전연결형의 세 가지 네트워크를 구분하여 집단응집력에 대한 효과를 연구하였다. 그 결과, 집단응집력은 네트워크의 집중도가 가장 낮은 완전연결형에서 가장 높게 나타났으며, 그 다음으로 원형에서 높게 나타나고 바퀴형에서 가장 집단응집력이 낮게 나타났다. 그러나 분산형 네트워크에서 참여도가 다른 원형과 완전연결형 간에서는 집단응집력이 차이를 보이지 않았다. 하지만 이전의 연구에서 네트워크를 두 부류로 분리한 집중형과 분산형 간의 비교분석에서 분산형 네트워크가 집중형 네트워크보다 집단응집력이 더 높게 나타났다. 본 연구는 커뮤니케이션 네트워크에서 불확실성의 상황변수가 집단응집력에 영향을 미친다는 사실을 규명하였으며, 이러한 집단응집력에 대한 불확실성의 효과는 불확실성 감소이론으로 설명할 수 있음을 밝혔으며, 집중형 네트워크는 과업 응집력이 작용하고 분산형 네트워크는 사회 응집력이 작용한다는 것을 규명하였다

이기종 전술통신망 종단간 암호화 통신을 위한 메커니즘

박철용(Cheol-Yong Park),김기홍(Ki-Hong Kim),류재철(Jae-Cheol Ryou) 한국정보보호학회 2014 정보보호학회논문지 Vol.24 No.4

전술통신망은 이기종 다양한 특성의 통신장비로 구성된 네트워크가 복합적으로 운용되고 있다. 이러한 구성으로 인해 종단간 통신을 위해 기종별 데이터 포맷으로 변환하기 위한 망연동 게이트웨이를 적용하고 통신 정보보호를 위해 네트워크별 암호기술이 적용되고 있다. 이는 이기종 망간 암호화된 데이터를 직접 전송할 수 없고 통신데이터의 재가공 및 처리지연의 문제점이 있다. 서로 다른 전술통신망 사이에 위치하는 망연동 게이트웨이에서 통신데이터에 대한 재가공과 암호화 데이터에 대한 복호화 및 재암호화가 요구된다. 본 논문에서는 전술통신망에서 이기종간 종단간 암호화 통신을 위한 통신방식을 제안한다. 제안한 방식을 이용하여 PSTN과 UHF 통신망간 게이트웨이에서 재가공, 재암호화, 전송 지연요소 등을 없애 실시간 음성 및 데이터 통신을 가능하게 한다. 또한, 종단간 정보보호를 위해 단대단 정보보호방식을 적용한다. 이를 통신망에 적용하여 기존 방식 대비 제안한 방식의 성능을 비교 분석한다. 제안한 방식은 기존방식의 문제점을 해결하고 이기종 전술통신망간 종단간 암호화 통신이 가능함을 확인하였다. Tactical networks is being operated in configuration that consisting of a variety of characteristics communication equipments and heterogeneous networks. In this configurations, end-to-end communication can be achieved using interworking gateway for converting the data format of the network and using encryption algorithm of the networks. The use of mechanism results in a problem that secure data cannot be transferred directly, reprocessing and processing delay of communication in heterogeneous tactical networks. That is, for encoding and decoding of data, the decryption of encrypted data and re-encryption processing must be required at the gateway between different networks. In this paper proposes to mechanism for end-to-end secure communication in heterogeneous tactical networks. Using the proposed method, end-to-end secure communication between heterogeneous tactical networks(PSTN-UHF networks) which removes the necessity of a gateway for converting data into data formats suitable for network to remove a transmission delay factor and enable real-time voice and data communication and achieve end-to-end security for heterogeneous tactical networks. we propose a novel mechanism for end-to-end secure communication over PSTN and UHF networks and evaluate against the performance of conventional mechanism. Our proposal is confirmed removal of security vulnerabilities, end-to-end secure communication in heterogeneous tactical networks.
