Abstract

The embodiment of the invention discloses a terminal communication voice encryption method and system. The method comprises the following steps: obtaining a first secret key from a first encryption card of a first terminal by the first terminal and sending a secret key negotiation request carrying the first secret key to a second terminal; receiving a message which is sent by the second terminal and shows that validation is passed; sending a voice frame to the first encryption card and encrypting the voice frame by using the first secret key; sending the encrypted voice frame to the second terminal. According to the terminal communication voice encryption method disclosed by the embodiment of the invention, communication voices are encrypted by a dynamic secret key and are not easy to decode, so that the safety is higher.

Description

technical field [0001] The invention relates to the field of communications, in particular to a terminal call voice encryption method and a voice encryption system. Background technique [0002] With the vigorous development of the communication industry, communication terminals such as mobile phones have become necessities of life. At the same time, the problem of user data leakage caused by stealing the call voice information of mobile phones through eavesdropping and other means is becoming more and more serious, causing great losses to mobile phone users. Therefore, mobile phones The security of the call is becoming more and more important. When making some important calls, the user can encrypt the voice of the call. [0003] Most of the voice and data encryption products in the prior art use a single key for encryption and decryption, but the single key is easy to decipher and has low security. Contents of the invention [0004] Embodiments of the present invention p...
