A Provably Secure Proxy Signature Scheme in Certificateless Cryptography
A proxy signature scheme enables an original signer to delegate its signing capability to a proxy signer and then the proxy signer can sign a message on behalf of the original sign...

Certificateless Group Oriented Signature Secure Against Key Replacement Attack
Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificate...

A Secure Nonrepudiable Threshold Proxy Signature Scheme with Known Signers
In the (t, n) proxy signature scheme, the signature, originally signed by a signer, can be signed by t or more proxy signers out of a proxy group of n members. Recently, an efficie...
