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

open access: yesCybernetics 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 ...

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

open access: yesJisuanji 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 ...

Attribute-Based Verifiable Conditional Proxy Re-Encryption Scheme

open access: yesEntropy, 2023
There are mostly semi-honest agents in cloud computing, so agents may perform unreliable calculations during the actual execution process. In this paper, an attribute-based verifiable conditional proxy re-encryption (AB-VCPRE) scheme using a homomorphic ...

Proxy Re-signature Schemes : Multi-use, Unidirectional & Translations

open access: yesJournal 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.

Multi-User and Multi-Replica Public Data Audit Scheme Supporting User Revocation [PDF]

open access: yesJisuanji gongcheng, 2020
Cloudstorage can help save local storage space when dealing with massive data,but increases the risk of data loss or damage.Although the existing audit schemes can verify the integrity of cloud data,it is mainly used in single-user single-replica ...

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

open access: yesJisuanji 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 ...

Proxy Re-signature Schemes Without Random Oracles [PDF]

open access: yes, 2007
To construct a suitable and secure proxy re-signature scheme is not an easy job, up to now, there exist only three schemes, one is proposed by Blaze et al. [6] at EUROCRYPT 1998, and the others are proposed by Ateniese and Hohenberger [2] at ACM CCS 2005.
