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 (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; (i) Advanced Encryption Algorithm (AES)-256, and (ii) Rivest Cipher 4 (RC4) Algorithm. Then, we analyze the computation time and show the secure connection to a legitimate base station during handover process.
