An Algorithm for Electronic Money Transaction Security (Three Layer Security) : A New Approach
Md. Syeful Islam 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.2
In the era of internet, most of the people all over the world completed their transaction on internet. Though the user of electronic transaction or E-money transaction system increase rapidly but the majority person are concern about the security of this system. The growth in online transactions has resulted in a greater demand for fast and accurate user identification and authentication. Conventional method of identification based on possession of ID cards or exclusive knowledge like a social security number or a password are not all together reliable. Identification and authentication by individuals' biometric characteristics is becoming an accepted procedure that is slowly replacing the most popular identification procedure – passwords. Among all the biometrics, fingerprint based identification is one of the most mature and proven technique. Along with the combination of conventional system, biometric security, Global positioning system(GPS) and mobile messaging we have design an algorithm which increase security of electronic transaction and more reliable to user. A three layer security model to enhancing security of electronic transaction is proposed in this paper.
Performance Evaluation of Finite Queue Switching Under Two-Dimensional M/G/1(m) Traffic
Islam, Md. Syeful,Rahman, Md. Rezaur,Roy, Anupam,Islam, Md. Imdadul,Amin, M.R. Korea Information Processing Society 2011 Journal of information processing systems Vol.7 No.4
In this paper we consider a local area network (LAN) of dual mode service where one is a token bus and the other is a carrier sense multiple access with a collision detection (CSMA/CD) bus. The objective of the paper is to find the overall cell/packet dropping probability of a dual mode LAN for finite length queue M/G/1(m) traffic. Here, the offered traffic of the LAN is taken to be the equivalent carried traffic of a one-millisecond delay. The concept of a tabular solution for two-dimensional Poisson's traffic of circuit switching is adapted here to find the cell dropping probability of the dual mode packet service. Although the work is done for the traffic of similar bandwidth, it can be extended for the case of a dissimilar bandwidth of a circuit switched network.
