Revocable identity-based proxy re-signature against signing key exposure. [PDF]
PLoS ONE, 2018 Identity-based proxy re-signature (IDPRS) is a novel cryptographic primitive that allows a semi-trusted proxy to convert a signature under one identity into another signature under another identity on the same message by using a re-signature key.

Proxy Re-signature Schemes : Multi-use, Unidirectional & Translations
Journal of Advances in Information Technology, 2011 In 1998, Blaze, Bleumer, and Strauss proposed proxy re-signatures, in which 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.

SRCPR: SignReCrypting Proxy Re-Signature in Secure VANET Groups
IEEE Access, 2018 Vehicular Ad hoc Network is an emerging area as a key component of the intelligent transport system. Despite the immense researches going on in this area, it is yet to be deployed at its full scale due to lack of trust, safety, and confidentiality in the

Provably secure certificate less blind proxy re-signatures
Tongxin xuebao, 2012 Using bilinear groups,an efficient certificate less blind proxy re-signature scheme was proposed based on the proxy re-signature scheme and blind signature scheme.The scheme solves the using of certificate in certificate-based scheme and removes key ...

Blind Proxy Re-Signature Scheme Based on Isomorphisms of Polynomials
IEEE Access, 2018 Most of the existing blind proxy re-signature schemes are designed based on the traditional public key cryptosystems, whose security relies on the hardness of big integer factoring, discrete logarithm, elliptic curve discrete logarithm, and so on ...

Partially blind proxy re-signature scheme with proven security
Tongxin xuebao, 2018 In order to solve the problem of anonymity and controllability of blind proxy re-signature,the concept of partially blind proxy re-signature was introduced by using the idea of partially blind signature.Furthermore,the security definition of partially ...

Proxy re-signature scheme based on isomorphisms of polynomial
Tongxin xuebao, 2017 Most of the existing proxy resignature schemes were based on the hardness of big integer factoring,discrete logarithm,elliptic curve.However,none of them can resist the attack by a quantum computer.Motivated by these concerns,a new proxy resignature ...

Unidirectional Variable Threshold Proxy Re-signature Scheme with Provable Security [PDF]
Jisuanji gongcheng, 2016 In most existing threshold proxy re-signature schemes,threshold value is essentially immutable.However,depending on the significance of re-signature message,the value should be changed dynamically in many practical applications.Based on proxy re ...
