Abstract :False Base Stations attack raises concerns about data privacy during handover process in 5G networks. Broadcasting of measurement reports unveils the need of security assessment since a false base station can send a stronger signal to the User Equipment insert ignore into journalissuearticles values(UE); to establish a connection with itself. This may cause to the leakage of information. Thus, a fundamental solution is to protect measurement reports with encryption algorithms. In this paper, we identify the security vulnerabilities of handover process and simulate a scenario, where a false base station is deployed and UEs can be connected it during handover process. In order to prevent this, we propose a secure handover scheme to protect measurement reports by using two encryption algorithms; insert ignore into journalissuearticles values(i); Advanced Encryption Algorithm insert ignore into journalissuearticles values(AES);-256, and insert ignore into journalissuearticles values(ii); Rivest Cipher 4 insert ignore into journalissuearticles values(RC4); Algorithm. Then, we analyze the computation time and show the secure connection to a legitimate base station during handover process.
