We propose a generalization of Paillier's probabilistic public key system, in which the expansion factor is reduced and which allows to adjust the block length of the scheme e...

Abstract— Under CPA and CCA1 attacks, a secure bit encryption scheme can be applied bit-by-bit to construct a secure many-bit encryption scheme. The same construction fails, howe...

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...
