In this paper, we propose a new approach for symbolic representation of off-line signatures based on relative distances between centroids useful for verification. Distances betwee...

We describe a short signature scheme that is strongly existentially unforgeable under an adaptive chosen message attack in the standard security model. Our construction works in g...

The Pintsov-Vanstone signature scheme with partial message recovery (PVSSR) is a variant of the Schnorr and Nyberg-Rueppel signature schemes. It produces very short signatures on ...

We investigate several previously suggested scenarios of instantiating random oracles (ROs) with “realizable” primitives in cryptographic schemes. As candidates for such “in...

Digital signature schemes are based on the assumption that the signing key is kept in secret. Ensuring that this assumption holds is one of the most crucial problems for all curre...
