An English auction is the most familiar type of auctions. Generally, an electronic auction has mainly two entities, the registration manager(RM) who treats the registration of bidd...
We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the...
Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against ...
