We describe and analyze a new digital signature scheme. The new scheme is quite efficient, does not require the the signer to maintain any state, and can be proven secure against ...

Multisignatures allow n signers to produce a short joint signature on a single message. Multisignatures were achieved in the plain model with a non-interactive protocol in groups ...

Abstract. We introduce a new undeniable signature scheme which is existentially unforgeable and anonymous under chosen message attacks in the standard model. The scheme is an embed...

Abstract. Recently we showed how to justify a Dolev-Yao type model of cryptography as used in virtually all automated protocol provers under active attacks and in arbitrary protoco...
