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.

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 ...

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 ...

Multi-use unidirectional proxy re-signatures [PDF]
Proceedings of the 15th ACM conference on Computer and communications security, 2008 In 1998, Blaze, Bleumer, and Strauss suggested a cryptographic primitive named proxy re-signatures where a proxy turns a signature computed under Alice's secret key into one from Bob on the same message. The semi-trusted proxy does not learn either party's signing key and cannot sign arbitrary messages on behalf of Alice or Bob.
