Abstract
A method and apparatus are disclosed and claimed which enable an entity to generate proofs of identity and signatures of messages that everyone can verify but no one can forge. Compared to other schemes of this type (such as the RSA), the Fiat-Shamir scheme is faster by one to two orders of magnitude. In the present invention disclosed and claimed in this patent application, two improved variants of the Fiat-Shamir scheme are described which are even faster. One variant uses small public values to optimize the vertification procedure, and the other variant uses particular secret values to optimize the generation procedure.
