(English Abstract)
In this paper, a merged TEA block cipher processor which unifies Tiny Encryption Algorithm(TEA), extended Tiny Encryption Algorithm(XTEA) and corrected block TEA(XXTEA) is designed. After TEA cipher algorithm was first designed, XTEA and XXTEA cipher algorithms were designed to correct security weakness. Three types of cipher algorithm uses a 128-bit master key. The designed cipher processor can encrypt or decrypt 64-bit message block for TEA/XTEA and variable-length message blocks up to 256-bit for XXTEA. The maximum throughput for 64-bit message blocks is 137Mbps and that of 256-bit message blocks is 369Mbps. The merged TEA block cipher designed in this paper has a 16% gain on the area side compared to a lightweight LEA cipher. The cryptographic IP of this paper is applicable in security module of the mobile areas such as smart card, internet banking, and e-commerce.
