SYMPES technique encoded IP-based secure voice communication system

Abstract

Need for end-to-end secure voice communication under the cyber security threats are increasing day by day. This paper describes a method of establishing secure VOIP system in which the voice encoded with the SYMPES [1] coding technique and encryption set with an open standard encryption algorithm. Voice can be transmitted from point to point within a secure IP network. A Graphic Processing Unit (GPU) based sub-structure will be placed to increase performance of the overall system under the heavy mathematical calculations of SYMPES algorithm.
