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...

A Secure and Efficient Authenticated Diffie-Hellman Protocol
The Exponential Challenge Response (XRC) and Dual Exponential Challenge Response (DCR) signature schemes are the building blocks of the HMQV protocol. We propose a complementary an...
