Signature Schemes Based on the Strong RSA Assumption
Ronald Cramer and Victor Shoup
Abstract: We describe and analyze a new digital signature scheme.
The new scheme is quite efficient, does not require the the signer
to maintain any state, and can be proven secure against adaptive
chosen message attack under a reasonable intractability assumption,
the so-called Strong RSA Assumption.
Moreover, a hash function can be incorporated into the scheme
in such a way that it is also secure in the random oracle model
under the standard RSA Assumption.
Category / Keywords: Signature, RSA, Strong RSA Assumption.
