Abstract

This paper presents a FPGA (Field Programmable Gate Array) based secured speech signal communication system. The system consists of compression, encryption and water- marking. Watermark provides authentication and ownership verification. Encryption is used for security of watermark and voice signal. As random numbers are used as a key for the encryption process, the signal is secured for both wired and wireless media. FPGA is an efficient device for encryption. Conventional processors contain small number of registers and perform large operations in multiple cycles. FPGA can perform a large number of operations at a time. All the steps described in the algorithm is verified in Matlab and implemented in FPGA. Security level is also analyzed in this paper. © 2010 IEEE.
