A proxy re-encryption system allows the proxy to transform ciphertexts encrypted under Alice’s public key into the different ciphertexts that can be decrypted by Bob’s secret ...

We present a fully homomorphic encryption scheme which has both relatively small key and ciphertext size. Our construction follows that of Gentry by producing a fully homomorphic s...

Abstract. A hidden vector encryption scheme (HVE) is a derivation of identity-based encryption, where the public key is actually a vector over a certain alphabet. The decryption ke...

A group oriented encryption scheme is presented in this paper. In this scheme, a sender is allowed to encrypt a message using the group public key and send the ciphertext to the gr...
