High-Speed Architecture Design and Implementation for SMS4-GCM

The notion of nonmalleable cryptography, an extension of semantically secure cryptography, is defined. Informally, in the context of encryption the additional requirement is that given the ciphertext it is impossible to generate a different ciphertext ...

Ma and Chen proposed a new authenticated encryption scheme with public verifiability. This scheme requires less computational costs and communication overheads than the conventional signature-then-encryption approaches. In this paper, we show that the ...
