We propose a convertible undeniable signature scheme without random oracles. Our construction is based on the Waters signatures proposed in Eurocrypt 2005. The security of our sche...

We study an adaptive variant of oblivious transfer in which a sender has N messages, of which a receiver can adaptively choose to receive k one-after-the-other, in such a way that ...
The design of cryptographic hash functions is a very complex and failure-prone process. For this reason, this paper puts forward a completely modular and fault-tolerant approach to...
