The ElGamal encryption scheme has been proposed several years ago and is one of the few probabilistic encryption schemes. However, its security has never been concretely proven bas...
This paper proposes a chosen-ciphertext secure variant of the ElGamal public-key encryption scheme which generates very compact ciphertexts for messages of arbitrary length. The ci...
The goal of this work is to separately control individual secure sessions between unlimited pairs of multicast receivers and senders while preserving the scalability of receiver i...
