Research on Parallel Dynamic Encryption Transmission Algorithm on VoIP

Abstract

Aiming to the current lack of VoIP voice encryption, a dynamic encryption method on grouping voice encryption and parallel encrypted is proposed in this paper. Though dynamic selection of encryption algorithms and dynamic distribution of key to increase the complexity of the encryption, at the same time reduce the time complexity of asymmetric encryption algorithm by using parallel encryption to ensure the real-time of the voice and improve call security.
