Security has become a highly critical issue in the provision of mobile services. The Wireless Application Protocol (WAP) has specified a powerful security layer, the WTLS. The Keyed-Hash Authentication Code (HMAC) has been adopted by the WTLS in order to support the special demands for authentication with security of high-level strength. A VLSI architecture and the FPGA implementation of HMAC for the WTLS are proposed in this work. The introduced design is based on the SHA-1 hash function. The implementation results for both the HMAC and the SHA-1 proposed architectures are compared with other related works. From these comparisons, it is proven that the proposed system performs better in all of the cases. It is also superior to the conventional hardware implementations by using the area-delay product. In addition to the WAP protocol, the proposed architecture can be implemented for any authentication system of computer networks and wireless protocols, with high-performance demands and hard secure authentication needs at the same time.
