Abstract: he operation mode of block cipher algorithm is vital to sensitive information security. In this paper, an Advanced Encryption Standard (AES) core which works in Cipher Block Chaining (CBC) is developed in reconfigurable hardware. The design of the key unit is optimized based on the analysis of AES. Simulation and experimental results show that in CBC mode the core can work steadily and encrypt/decrypt sensitive information in high speed.

Key words:  advanced encryption standard, cipher block chaining, reconfigurable hardware implementation
