Generating Multi-Issued Session Key by Using Semi Quantum Key Distribution With Time-Constraint

Abstract

Information security refers to protect the information from unauthorized access or modification. Quantum Key Distribution (QKD) is a way to generate a key preventing those malicious activities. One of QKD protocol, namely Semi-quantum key distribution (SQKD) protocol, is designed to allow two users to establish a secure secret key when either of them is limited to performing certain “classical” operations. It is proven to be secure from any type of attack. However, it will be a problem in the multi-session communication since the SQKD activities follow the number of the session. In this paper, we propose two modified SQKDs with time-constraint approach. Time-constraint is beneficial in QKD activity since it could generate session key between two parties within a certain time-constraint. By setting the number of session key and its time-constraint before QKD activities, many scheduled communications would be prepared well. Furthermore, BAN Logic analysis is applied to analyze the goal of the protocol, the considered assumptions, wasted phase, and the demand for data encryption. Finally, the performance analysis of the protocols is presented, and it shows a better performance compared with other certain QKDs.
