To protect the implementation of the standard Secure Hash Algorithm (SHA) against attacks. We have proposed a number of countermeasures. This paper present a proposed new fault detection scheme. It is based on the hybrid redundancy. The simulation results prove that the fault coverage achieves 99.999% for our scheme proposed. Also, our proposed detection scheme has been implemented on Xilinx Virtex-II Pro FPGA. It is fault coverage, area degradation, frequency, throughput and efficiency overhead have been compared and it is shown that the proposed scheme allows a trade-off between the security and the implementation cost of the SHA implementation.
