The environment of smart card lacks of system resources but the commercial and economic transactions via smart cards demand the use of certificated and secure cryptographic methods. In this paper a cryptographic approach in hardware for smart cards is proposed. The proposed system supports two basic operations of cryptography, authentication and encryption. The basic component of system is the one round of DES algorithm which supports the DES, Triple DES and the ANSI X9.17 standards. The proposed system is efficient in terms of area resources and techniques for low power consumption have applied. Due to the fact that the system is for smart card applications the overall throughput outperforms the typical smart card throughput standards.
