| Abstract: | We describe matrix free pivotal algorithms in the XTR+ system. The computation efficiency of the pivotal algorithms is obviously improved. Consequently, the
computation efficiency of the provable IND CCA2 secure cryptosystem, the provable secure digital signature, the provable secure blind signature protocol and zero knowledge proof protocol by means of XTR+ system is also improved greatly. |
