Two-Tier Signatures, Strongly Unforgeable Signatures, and Fiat-Shamir Without Random Oracles
We provide a positive result about the Fiat-Shamir (FS) transform in the standard model, showing how to use it to convert threemove identification protocols into two-tier signatur...

Proving Tight Security for Rabin-Williams Signatures
This paper proves "tight security in the random-oracle model relative to factorization" for the lowest-cost signature systems available today: every hash-generic signatur...

Strengthened Security for Blind Signatures
Abstract. Provable security is a very nice property for cryptographic protocols. Unfortunately, in many cases, this is at the cost of a considerable loss in terms of efficiency. Mo...

Strong Anonymous Signatures
The notion of anonymous signatures has recently been formalized by [18], which captures an interesting property that a digital signature can sometimes hide the identity of the sign...
