Identity-Based Blind Proxy Re-Signature Scheme for Data Security

2018 IEEE Third International Conference on Data Science in Cyberspace (DSC), 2018
Identity-based blind proxy re-signature (IDBPRS) not only has the functionality of signature conversion, but also can protect the privacy of the signed data. In this paper, we present an efficient IDBPRS scheme in the standard model. The proposed scheme is blind and bidirectional, and is proven to be existentially unforgeable under the Diffie-Hellman ...

Universally composable secure proxy re-signature scheme with effective calculation

Cluster Computing, 2017
In proxy re-signature scheme, the semi-trust proxy is given special information to convert user A’s signature into another user B’s signature on the same message m. This has numerous application, such as simplifying the certificate management by constructing a secure channel between two authentication centers, simplifying group signature management by ...

Security Analysis and Improvement of Partially Blind Proxy Re-signature Scheme

Proceedings of the 8th International Conference on Communication and Network Security, 2018
As a new concept proposed recently, partially blind proxy re-signature scheme (PBPRSS) holds the advantages of the partially blind signature and proxy re-signature. In PBPRSS, a semi-trust third party called the proxy can re-sign a message with a piece of common information between the delegator and the proxy by a re-signature key.

Improvement of ID-based proxy re-signature scheme with pairing-free

Wireless Networks, 2019
As an all-important cryptographical technique, proxy re-signature (PRS) is broadly applied to distributed computation, copyright transfer and hidden path transfer because it permits a proxy to translate an entity’s signature into another entity’s signature on the identical message.
