Nominative Proxy Ring Signature
2009 10th ACIS International Conference on Software Engineering, Artificial Intelligences, Networking and Parallel/Distributed Computing, 2009In a nominative proxy ring signature scheme, an original signer delegates his nominative signing power to some proxies forming a ring. The member of the ring can generate a nominative signature on behalf of the original signer and the ring. In a nominative proxy ring signature scheme, only the nominee can verify the ring signature and if necessary ...

Certificateless multi-proxy signature
Computer Communications, 2011Multi-proxy signature is a scheme that an original signer authorizes a proxy group as his proxy agent and later only the cooperation of all proxy signers in the proxy group could sign messages on behalf of the original signer. To our best knowledge, most of the existing multi-proxy signature schemes are proposed in public key infrastructure or identity-

Certificate-based proxy signature
2010 IEEE International Conference on Progress in Informatics and Computing, 2010Certificate-based public key cryptography was introduced to remove the use of certificate to ensure the authentication of the user's public key in the traditional cryptography and overcome the key escrow problem in the identity-based public key cryptography.

In a proxy re-signature scheme a semi-trusted proxy acts as a translator between Alice and Bob to translate a signature from Alice into a signature from Bob on the same message. In the 12th ACM CCS 2005, Ateniese and Hohenberger presented two secure proxy re-signature schemes based on bilinear maps and left as open challenges the design of multi-use ...

Deniable Partial Proxy Signatures
2004This paper describes a proxy signature scheme where a signer can delegate a partial signing right to a party who can then sign on behalf of the original signer to generate a partial proxy signature. A partial proxy signature can be converted into a full signature with the aid of the original signer.

Controlled Proxy Re-signing - Conditional Proxy Re-Signatures
Proceedings of the 12th International Conference on Security and Cryptography, 2015Delegation of authentication is one of the vital security management strategies to manage device authentication in an enormous network. Major issue while delegating authentication using traditional proxy cryptography is that the delegator loses control over the messages which are authenticated by the delegatee and in proxy recryptography controlling ...

On constructing certificateless proxy signature from certificateless signature
Journal of Shanghai Jiaotong University (Science), 2008In proxy signature schemes, an original signer A delegates its signing capability to a proxy signer B, in such a way that B can sign message on behalf of A. The recipient of the final message verifies at the same time that B computes the signature and that A has delegated its signing capability to B.

Threshold proxy signature schemes
1998Delegation of rights is a common practice in the real world. Proxy signature schemes have been invented to delegate signing capability efficiently and transparently. In this paper, we present a new nonrepudiable proxy signature scheme. Nonrepudiation means the signature signers, both original and proxy signers, cannot falsely deny later that he ...
