New signature schemes in the standard model based on publicly verifiable CCA-secure public key encryption
Haining Luo, Xu An Wang · International Journal of Information and Communication Technology · 2015
Till now, there are not many ways to construct signature schemes in the standard model and recently many researchers show great interest in construction secure signatures in the standard model. CCA secure publicly verifiable public key encryption in the standard model (PVPKE) is a new interesting primitive, in which the ciphertext's validity/integrity can be publicly verified. In this paper, we propose a new way to construct signature schemes in the standard model. That is, transforming CCA secure publicly verifiable public key encryption schemes into signature schemes. Our transformation based on the following facts: 1) the signature scheme and CCA secure publicly verifiable public key encryption scheme share the same 'publicly verifiability' property; 2) the signature scheme requires the signatures can not be malleable, and CCA secure publicly verifiable public key encryption also require the ciphertexts can not be malleable; 3) public key encryption and digital signature schemes can be viewed as dual of each other. By utilising these facts, we try to give a new way to construct signature scheme in the standard model.
