Abstract
For the GSM security mechanism cannot assure end-to-end secure communications, this paper presents a novel voice encryption method based on current voice channel, which overcomes data channel´s shortages and solves the problem of voice encryption penetrating the RPE-LTP vocoder. The proposed method realizes the end-to-end secure communications in the GSM system with short time delay, good compatibility to all GSM networks, and easy implementation without any modification in current GSM signaling system.
