A Study on the High Speed Crypto-System for the Multi-Sessions

摘要

According to improve the high performance computer and high speed networks, the efficient data encryption and decryption are needed in high speed information technologic environments. But the performance of cryptosystem is lower than computer network system, because the cryptosystem has to process a lot of commands such as arithmetic, modular exponentiation, and permutation. Since the computer network system with cryptosystem could be low performance and delaying the computing, the high speed crypto chips have being developed. But most of them have a limit of improving performance at a speed to process packets in multi- sessions. In this paper we suggest the architecture of cryptosystem which is able to carry out incoming multi- session's packets. Since this system do not need the session switching in CPU, it reduces the amount of work in CPU. We show that our cryptosystem have the better performance than other system through the simulation.
