Provably-Secure Certificateless Proxy Re-signature Scheme
2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013The paper proposes a provably-secure certificateless proxy re-signature scheme. Based certificateless public cryptosystem, it solves the using of certificate in certificate-based scheme and removes key escrow in ID-based scheme. Analysis shows that the proposed scheme can satisfy the required properties of a proxy re-signature, and it avoids public key

The Security Model of Unidirectional Proxy Re-Signature with Private Re-Signature Key
2010In proxy re-signature (PRS), a semi-trusted proxy, with some additional information (a.k.a., re-signature key), can transform Alice's (delegatee) signature into Bob's (delegator) signature on the same message, but cannot produce an arbitrary signature on behalf of either the delegatee or the delegator.

A special purpose proxy re-signature scheme
2012 International Conference on Innovations in Information Technology (IIT), 2012In a proxy re-signature scheme, a semi-trusted entity called proxy is capable of transforming Alice's signature on a message m into Bob's signature on m, with the help of some private information. In this paper, we have addressed the open problem of converting one type of signature into another, this was posed as an interesting issue by Ateniese and ...

A multi-use unidirectional certificateless proxy re-signature scheme
Telecommunication Systems, 2019Proxy re-signature (PRS) allows a semi-trusted proxy served as a translator to transform a signature of delegatee into a signature of delegator on the same message. The heavy overhead of certificate management and the key escrow problem hinder the development of the public key infrastructure-based PRS scheme and the identity (ID)-based PRS ...

Proxy Re-Encryption and Re-Signatures from Lattices
2019Proxy re-encryption (PRE) and Proxy re-signature (PRS) were introduced by Blaze, Bleumer and Strauss [Eurocrypt ’98]. Basically, PRE allows a semi-trusted proxy to transform a ciphertext encrypted under one key into an encryption of the same plaintext under another key, without revealing the underlying plaintext.

Non-interactive Conditional Proxy Re-Signature in the Standard Model
The Computer Journal, 2018Proxy re-signature allows a semi-trusted proxy to transform a delegatee's signature on a message into a delegator's signature on the same message. To transform a signature, the proxy uses a re-signature key that is received from the delegator. Once the proxy has received the re-signature key, the proxy can transform all the delegatee's signatures to ...

Threshold proxy re-signature: definition and new constructions
Journal of the Chinese Institute of Engineers, 2018The previous threshold proxy re-signature schemes have been mainly constructed with bilinear maps, the implementations of which are much more time-consuming than exponentiation operations.

Proxy Re-Signature Scheme from CBS to IBS
Advanced Materials Research, 2011In 1998, Blaze, Bleumer and Strauss proposed a new kind of cryptographic primitive called proxy re-signature. In proxy re-signature, a proxy can transform a signature computed under Alice’s secret key into one that can be verified by Bob’s public key. In 2005, Ateniese et al proposed a few re-signature schemes and also discussed its several potential ...

Designated Verifier Proxy Re-signature for Deniable and Anonymous Wireless Communications
Wireless Personal Communications, 2017In this paper, we introduce a new cryptographic primitive named Designated Verifier Proxy Re-Signature (DVPRS). Different from a normal proxy re-signature, our DVPRS is defined based on the notion of Designated Verifier Signature (DVS) which is very useful in many applications that require "deniable authentication".
