Document Type and Number:
WIPO Patent Application WO/2018/153011
Kind Code:
A1
Abstract:
Disclosed are an end-to-end voice encryption apparatus and encryption method for an intercom system, said encryption apparatus comprising: a voice acquisition and playback module, which acquires and plays back voice of the two parties of a call; a voice compression encoding and decoding module, which compression-encodes sent audio data and decodes and restores received audio data; an encryption and decryption processing module, which performs encryption and decryption processing on transmitted voice data and performs dynamic key replacement at each session, such that there is one key for each call; a data transmission processing module, used for sending and receiving audio data and performing encryption and decryption of audio data by means of invoking the encryption and decryption processing module. In comparison with the prior art, the present invention (1) achieves Plug and Play with any intercom system, and has a very broad range of applications; (2) performs encryption using one key for each call, resisting any wiretapping and deciphering and very effectively preventing various security risks, and is highly reliable; (3) as an independent function module, is completely independent of a communications system and does not directly access a channel, greatly reducing application limitations; at the same time, it has the advantages of high security and low latency and is suitable for large-scale and widespread application.
