Perspective Chapter: The Importance of Pipeline in Modern Cryptosystem

Abstract

In this digital world, all the digital information transmitted through the wireless channel has a threat to its security. Along with security, encryption speed is also a significant factor in transmitting the data as fast as possible. The pipeline is the technique used to improve the throughput of the encryption process so that the amount of data encrypted per unit time will be increased. In this chapter, the design of the modern SMS4-BSK cryptosystem is briefed, various pipeline designs of SMS4 algorithms are surveyed and the pipeline implementation on SMS4-BSK cryptosystem is analyzed. The SMS4-BSK cryptosystem is robust, fast and has a throughput of 7.4 Gbps. This modern cryptosystem can resist all kinds of cryptanalysis attacks. The pipelining technique is implemented in this cryptosystem to improve the throughput further. The pipelining method is applied in the encryption architecture of the cryptosystem. The pipelined design is implemented in Kintex-7 FPGA. The design achieved a throughput of 9.9 Gbps. The pipeline implementation can be extended to the key scheduling architecture also as both the encryption and the key scheduling use the same architecture. As per the SMS4-BSK algorithm, the keys are generated in the host system to improve the throughput.
