Improvement of Pivotal Algorithms in XTR~+ Public Key System
Shugong Zhang · Journal of Jilin University(Science Edition) · 2009
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.
