Abstract: To the problems of running speed and security of current RSA digital signature,a high-speed,efficient,and compact-structured RSA digital signature algorithm is implemented by using of FPGA. RSA and Keccak algorithms are used as the main modules in our scheme,major structure of this signature algorithm is the modular exponentiation based on Montgomery modular multiplication algorithm and R_L model algorithm,Keccak,the new generation sha-3 algorithm,also is used as its one-way hash function,which further strengthens the security and speed of this signature algorithm. This signature algorithm is finally realized by parallel operation of pipeline technology. Simulation testing shows it is just 7us for running 1024bit modular multiplication.
