An aggregate signature scheme is a digital signature scheme where anyone given n signatures on n messages from n users can aggregate all these signatures into a single short signa...
d Abstract) Ran Canetti and Marc Fischlin Abstract. We propose a new security measure for commitment protocols, called Universally Composable (UC) Commitment. The measure guarantee...
We demonstrate how the framework that is used for creating efficient number-theoretic ID and signature schemes can be transferred into the setting of lattices. This results in cons...
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...
