Server-Aided Verification Proxy Re-signature
2013 12th IEEE International Conference on Trust, Security and Privacy in Computing and Communications, 2013Proxy re-signature is proposed by Blaze, Blemmer and Strauss (BBS), in which a semi-trusted proxy acts as a translator converts a signature from Alice into a signature from Bob on the same message. Proxy re-signature is a very useful tool for the interoperable DRM architecture and the proof of passed path in cloud computing.

Unidirectional Identity-Based Proxy Re-Signature
2011 IEEE International Conference on Communications (ICC), 2011To construct a suitable and secure proxy re-signature scheme is not an easy job, up to now, there exist only a few schemes. None of these schemes is unidirectional identity-based proxy re-signature, where a semi-trusted proxy can transform a signature under an identity to another signature under another identity on the same message, while the proxy ...

A unidirectional certificateless proxy re‐signature scheme based on lattice
Transactions on Emerging Telecommunications Technologies, 2021AbstractAs a kind of special digital signature, proxy re‐signature is becoming more and more important in transparent certification and management of group signatures. But most existing proxy re‐signature schemes cannot resist collusion attack. So we construct a scheme by using dual modulus technology and lattice structure.

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 ...

Proxy Re-signatures in the Standard Model
2008This paper studies proxy re-signature schemes. We first classify the expected security notions for proxy re-signature schemes with different properties. We then show how to attack on a recently proposed bidirectional scheme that is purported to be secure without random oracles, and discuss the flaw in their proof.

On DDos Attack against Proxy in Proxy Re-encryption and Proxy Re-signature
2009 Ninth IEEE International Conference on Computer and Information Technology, 2009In 1998, Blaze, Bleumer and Strauss proposed new kind of cryptographic primitives called proxy re-encryptionand proxy re-signature. In proxy re-encryption, a proxy cantransform a ciphertext computed under Alice's public key intoone that can be opened under Bob's decryption key. In proxyre-signature, a proxy can transform a signature computed underAlice'

Proxy Re-signature Supporting Conditional Delegation
2015 10th International Conference on P2P, Parallel, Grid, Cloud and Internet Computing (3PGCIC), 2015In proxy re-signature (PRS), a signature computed by Alice's secret key can be transferred to be a new signature by a proxy equipped with the re-signature key, while the new signature can be verified by Bob's public key. However, until now all the PRS scheme have this feature: the proxy can transfer all the delegatee's signature to be the delegator's ...

A certificateless proxy re-signature scheme
2010 3rd International Conference on Computer Science and Information Technology, 2010Proxy re-signature is greatly concerned by researchers recently. It is a very useful tool for sharing web certificates, forming weak group signatures, and authenticating a network path. In this paper, we propose the first certificateless proxy re-signature scheme.

ID-based proxy re-signature without pairing
Telecommunication Systems, 2018Proxy re-signature is a powerful cryptographic primitive, in which a proxy acts as a translator converts Alice’s signature into Bob’s signature by using the re-signature key. Proxy re-signature is a very useful tool for the interoperable DRM architecture and the passed path proof in cloud computing.

An Efficient Proxy Re-Signature Over Lattices
2019In 2008, Libert and Vergnaud constructed the first multi-use unidirectional proxy re-signature scheme. In this scheme, the proxy can translate the signatures several times but only in one direction. Thus, two problems remain open. That is, to construct a multi-use unidirectional proxy re-signature scheme based on classical hardness assumptions, and to ...
