Since all data input and output to a cryptographic module must occur through its interface, performance degradation coming from interface constraints is inevitable for small data packets even the best-performing cipher chip. This paper proposes the High-Speed Packet Cipher System that encrypts even small packet data at high speed by improving the packet data processing method used in existing cryptographic modules. Looking at the test result, we see that speed of 68Mbps better than 0.5Mbps of 4-step Procedure is achieved for 32-byte packets.
