The Full-Domain Hash (FDH) signature scheme [3] forms one the most basic usages of random oracles. It works with a family F of trapdoor permutations (TDP), where the signature of m...

We show that every construction of one-time signature schemes from a random oracle achieves black-box security at most 2(1+o(1))q , where q is the total number of oracle queries a...
Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a...
In response to the Mumbai attacks of 2008, the Mumbai police have started to schedule a limited number of inspection checkpoints on the road network throughout the city. Algorithm...

Abstract. Oracle separation methods are used in cryptography to rule out blackbox reductions between cryptographic primitives. It is sufficient to find an oracle relative to whic...
