End-to-end encrypted communication security technology for mobile terminals

Abstract

With the development of mobile terminals, users often send important private information such as bank accounts and passwords through mobile terminals. However, the public mobile communication system has not yet provided the end-to-end encrypted transmission service of user data, which cannot guarantee the security of user data transmission. Therefore, this paper adopts the end-to-end encryption technology to study the communication security technology in mobile terminals. Firstly, this paper uses smart card for encryption and decryption operation and secure storage of key. Secondly, a multi-level key management mechanism is adopted to update the key regularly. Finally, the bidirectional authentication between the terminal and the key management centre, and the authentication between the application program and the user are realised. Simulation results show that the scheme can guarantee the confidentiality and integrity of messages during transmission and terminal storage, can resist the attack of mobile terminal malware, and realise the security of user communication.
