Implementation of schnorr signcryption algorithm on DSP

Abstract

The lack of data security in public mobile telecommunication system increases the need for a strong data protection and security mechanisms. Cryptography is considered as one of the key elements that provides security for mobile systems. Signcryption algorithm, which is based on public key cryptography, provides both confidentiality and authenticity in one step. Moreover, hardware implementations of cryptographic algorithms provide scalable solutions to enhance the level of security of the existing hardware. In this paper, we present a case study on using a DSP board to construct a secure communication channel. We use the constructed DSP board as a hardware cryptosystem to increase the security of transmitted data using any mobile communication system. We evaluate the performance by computing the consumed time by encryption/decryption process, while implementing the Schnorr Signcryption scheme on a DSP. Furtheremore, we propose an enhanced model of applying multiple DSP using pipelines and parallelization technique to decrease the consumed time in the whole process.
