In a network communication process, cryptographic algorithms play important role for secure process. This paper presents a new system architecture named "DCCS." This system can handle flexible operations of both cryptographic algorithms and the keys. For experimental evaluation, two representative cryptographic algorithms DES and Triple-DES are designed and implemented into an FPGA chip on the SEBSW-1. Then the developed board is confirmed to change its cryptographic algorithms dynamically. Also its throughput confirmed the ability of the real-time net-work use of the designed system.
