Abstract
Voice over Internet Protocol (VoIP) achieves cheap cost and provides flexible features by delivering voice packet over Internet Protocol. Compared with conventional public-switched telephone network, transmitting voice packets over public channel has to face more challenges due to the security threats and quality loss. To protect the voice packets transmitted over unsecured Internet, a shared key should be updated during a VoIP call. On the other hand, VoIP is more sensitive to transmission latency, so the flooding message traffic from key updating may cause the degradation of speech quality. This paper presents a dynamic key updating scheme without affecting the quality of VoIP calls. Unlike previous works, steganography technology is employed with encryption to provide protection of transmitted information in an unsecure channel. Moreover, in the proposed scheme, the quality of the VoIP call is preserved by adopting steganography technology to avoid the flooding message traffic. The security analysis demonstrates that the proposed scheme achieves the secure dynamic key updating without sacrificing the quality of VoIP calls.
