Authentication is an important security measure for multicast applications, providing receivers with confidence that the packets they receive are valid. Simply signing every multi...
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...
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...
We present the first aggregate signature, the first multisignature, and the first verifiably encrypted signature provably secure without random oracles. Our constructions derive f...

Abstract— Most e-government applications have to find a solution for simple, reliable, secure and authentic signing of official documents. Citizens need a simple way to verify ...
