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.

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 ...

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 ...

A Survey on Proxy Re-Signature Schemes for Translating One Type of Signature to Another [PDF]

Cybernetics and Information Technologies, 2021
Proxy Re-Signature (PRS) complements well-established digital signature service. Blaze-Bleumer-Strauss discussed PRS in 1998 for translating a signature on a message from Alice into a signature from Bob on the same message at semi-trusted proxy which ...

ID-based Sever-aided Verification Proxy Re-signature Scheme [PDF]

Jisuanji gongcheng, 2017
Signature verification in the existing ID-based proxy re-signature schemes includes time-consuming bilinear pairing operations,which are not suitable for low-power devices.In order to improve the efficiency of signature verification,combined with server ...

Integrity Verification Scheme for Cloud Data Based on Proxy Re-signature [PDF]

Jisuanji gongcheng, 2018
A new integrity verification scheme for cloud data is proposed to solve the problems of dynamic data updating and user revocation.The new scheme uses proxy re-signature to transfer data ownership and revoke users.By using the random masking technique,it ...

E-government Data Security Exchange Scheme Based on Proxy Re-signature [PDF]

Jisuanji gongcheng, 2017
Considering the security problem of e-government data exchange,a double trapdoor Hash function is proposed by using discrete logarithm assumption.Moreover,this function is proved to satisfy the properties,such as validity,trapdoor collision,collision ...
