Abstract

Main characters of the invention are that an encrypting and decrypting device is added to interface of the current communication terminal device in order to carry out encrypting or decrypting process for audio signal. Thus, the invention makes current communication network and device possesses function for transferring the encrypted voice. The invention raises use ratio of current equipment, and prevents action of monitoring communication effectively. User can select whether communication is encrypted or not freely. Features are: easy of use, and portable.

Description

technical field [0001] The present invention relates to a method and a device for implementing voice encryption in a communication system, a method and a device for supporting and realizing voice encrypted communication by utilizing an existing communication exchange system (including fixed communication and mobile communication), and especially relates to System composition and implementation technology for encrypted voice transmission in the field of communication. Background technique [0002] With the continuous development of communication technology, not only the communication system is required to have the characteristics of high quality, multi-function, and high reliability, but also higher and higher requirements are put forward for the confidentiality of the communication system. The scope of encrypted communication extends from special users to ordinary users. user. The concealment, confidentiality and security provided by the existing communication systems canno...
