Deniable Partial Proxy Signatures

2004
This 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.

Design of Proxy Signature in ECDSA

2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008
DSA and ECDSA are two standard signatures, which have been fully discussed and well accepted. However, they both lack functionality of proxy signature. On the other hand, most of the proxy signature schemes, which have been proposed prior to this date, are seldom based on standard signatures.

Proxy Re-signature Schemes

2008
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 ...

Certificateless multi-proxy signature

Computer Communications, 2011
Multi-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-

Nominative Proxy Ring Signature

2009 10th ACIS International Conference on Software Engineering, Artificial Intelligences, Networking and Parallel/Distributed Computing, 2009
In 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 ...

Verifiable Timed Proxy Signatures and Multi-signatures.

IACR Cryptol. ePrint Arch., 2023
Verifiable timed commitments serve as cryptographic tools that enable the binding of information to specific time intervals. By inte- grating these commitments into signature schemes, secure and tamper- evident digital signatures can be generated, ensuring the integrity of time-sensitive mechanisms.

A BATCH VERIFICATION FOR MULTIPLE PROXY SIGNATURE

Parallel Processing Letters, 2011
In this article, we proposed a batch verification scheme for multiple proxy signatures to reduce the proxy signature verification time. The proposed scheme is not only efficient because it does not verify each individual proxy signature separately, but also secure because it can detect forged multiple proxy signatures without failure.

Efficient Certificateless Proxy Signature Scheme

International Journal of Foundations of Computer Science, 2016
A proxy signature scheme allows a proxy signer to sign messages on behalf of an original signer within a given context. We propose a certificateless proxy signature (CLPS) scheme, and prove it's security under a stronger security model. Although some good results were achieved in speeding up the computation of pairing function in recent years, it is ...

Ring proxy signatures

Journal of Electronics (China), 2008
Proxy signatures have been used to enable the transfer of digital signing power within some context and ring signatures can be used to provide the anonymity of a signer. By combining the functionalities of proxy signatures and ring signatures, this paper introduces a new concept, named ring proxy signature, which is a proxy signature generated by an ...
