In this study, we present a new scheme for smart education utilizing the concept of a blockchain for question sharing. A two-phase encryption technique for encrypting question papers (QSPs) is proposed. In the first phase, QSPs are encrypted using a timestamp, and in the second phase, previously encrypted QSPs are encrypted again using a timestamp, salt hash, and hash from the previous QSPs. These encrypted QSPs are stored in a blockchain along with a smart contract that helps the user to unlock the selected QSP. An algorithm is also proposed for selecting a QSP for the exam that randomly picks a QSP. Moreover, a timestamp-based lock is imposed on the scheme so that no one can decrypt the QSP before the allowed time. Security analysis is conducted to demonstrate the feasibility of the proposed scheme against different attacks. Finally, the effectiveness of the proposed scheme is demonstrated through implementation, and the superiority of the proposed scheme over existing schemes is proven through a comparative study based on different features.

Natural disasters visited countries every year more or less and left devastating situations behind, which affect both the economy and health. However, instantaneous actions can lessen casualties in the affected areas. Unmanned any vehicle (UxV) is a concept where unmanned vehicles come together and perform missions cooperatively. UxV can assist in rehabilitating the affected area. Multi-access edge computing (MEC) can assist UxVs in real-time. However, disaster might jeopardize MEC structure. Home edge computing (HEC) is a paradigm that stays closer to the end devices and enables an offline computation environment. HEC can fill up the gap and assist in maintaining the mission. Besides, networks and data are surrounded by security and privacy issues. This paper introduces a blockchain-based HEC assisted disaster rehabilitation and recovery scheme to restore everyday life using UxV. A proof of concept is considered for proving the feasibility.
A Blockchain-Enabled Drone-Facilitated Home Quarantine Supervision Scheme in Pandemic Situations

Pandemics are very burdensome for every country in terms of health and economy. Technology is needed to come forward to lessen the burden. As finding cure instantly is not always possible, prevention method can be adopted to reduce the damages. Among the methods, home quarantine (HQ) can be beneficial. However, maintaining HQ is very difficult, especially in remote areas where network connectivity is very limited. Drones, dew computing, and blockchain are emerging technologies which can assist in reducing damages. This paper presents a blockchain enabled home quarantine supervision scheme in which patients are monitored using drones. A lightweight computation environment is established to assist the drone. A proof of concept is established to demonstrate the feasibility.
BUAV: A Blockchain Based Secure UAV-Assisted Data Acquisition Scheme in Internet of Thing
Anik Islam,신수영 한국통신학회 2019 Journal of communications and networks Vol.21 No.5
Internet of things (IoT), mobile edge computing (MEC),and unmanned aerial vehicle (UAV) have attracted significant attentionin both industry and academic research. By consolidatingthese technologies, IoT can be facilitated with improved connectivity,better data transmission, energy saving, and other advantages. However, the communication between these entities is subject topotential cyber threats. In addition, the integrity of the data mustbe maintained after storing into local storage. Blockchain is a datastructure that supports features like pseudonymity, data integrityetc. This paper represents a blockchain based data acquisition processin which information is gathered from IoTs using UAV as arelay and is securely kept in blockchain at MEC server. In the proposedscheme, data are encrypted prior to transfer to MEC serverwith the assistance of a UAV. Upon receiving the data, MEC servervalidates the data and the identity of the sender. Successful validationis followed by stocking of the data into blockchain, subsequentto obtaining consent from the validators. Security analysisis conducted in order to show the feasibility of the proposed securescheme. Finally, the performance of the proposed scheme is analyzedvia simulation and implementation.
