In a traditional signature scheme, a signature on a message m is issued under a public key PK, and can be interpreted as follows: "The owner of the public key PK and its corr...
The strongest standard security notion for digital signature schemes is unforgeability under chosen message attacks. In practice, however, this notion can be insuļ¬cient due to ā...

The Fiat-Shamir (FS) transform is a popular tool to produce particularly eļ¬cient digital signature schemes out of identiļ¬cation protocols. It is known that the resulting signat...
Abstract. Digital signatures are often proven to be secure in the random oracle model while hash functions deviate more and more from this idealization. Liskov proposed to model a ...
A number of signature schemes and standards have been recently designed, based on the Discrete Logarithm problem. In this paper we conduct design validation of such schemes while t...
