Mobile terminal voice end-to-end encryption method based on ios operating system

Abstract

The invention relates to an end-to-end encryption method for voice of a mobile terminal based on an iOS operating system, which is suitable for WiFi / 3G / 4G networks, and includes a call processing module, an identity authentication module, a key negotiation module, a voice input and output module, and voice encryption and decryption There are seven modules in total including processing module, protocol analysis module and network transceiver module. The overall flow of the implemented end-to-end voice communication method includes five steps: the calling party initiates a call, identity authentication, key agreement, the called party responds to the call, and encryption and decryption communication steps. The invention provides an end-to-end voice communication scheme applicable to the iOS system, including encryption and authentication functions, which encrypts and authenticates the identities and voice data packets of both parties in the call, and the two parties in the call realize a voice call through key negotiation. Yimi realizes end-to-end secure voice communication in a convenient and efficient way.

Description

technical field [0001] The invention relates to the fields of information security, mobile communication, and mobile phone operating systems, and particularly proposes an end-to-end encryption method for mobile terminal voice applied to an iOS operating system. Background technique [0002] With the rapid development of communication technology and the advent of the mobile Internet era, people's work and life have become increasingly inseparable from smartphones. And iOS is one of the most popular smartphone operating systems. The iOS system has attracted more and more high-quality users due to its better stability, fluency, power consumption control and background mechanism. iOS users are usually concerned about communication security. , privacy protection, etc. have higher requirements. However, with the rampant of fake base stations and the large-scale spread of eavesdropping technology, especially with the "Prism Gate" eavesdropping incident revealed by Snowden, the com...

Problems solved by technology

However, this method needs to dynamically select an encryption algorithm, which has high complexity and is likely to cause a large delay; and this method does not provide identity authentication, and cannot guarantee the identity security of both parties in communication, and this method does not involve the iOS system.
