Abstract
With the increasing popularity of 4G networks, communication technology based on VoLTE protocol has gradually become more and more mature. However, the public pay more attention to data security in the communication. We modify the baseband protocol of mobile phone with C language and assembly language in Android system and the encryption scheme for VoLTE protocol adds the key agreement and the improved RC4 encryption algorithm by capturing and analyzing the RTP packets in the communication. Finally, end-to-end VoLTE encrypted communication is implemented to protect user communication security and avoid the third party stealing data.
