Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...

Current techniques for transforming unforgeable signature schemes (the forged message has never been signed) to strongly unforgeable ones (the forged message could have been signed...

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...

Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

Recently, there are several generic transformation techniques proposed for converting unforgeable signature schemes (the message in the forgery has not been signed yet) into strong...
