Untraceability of Partial Blind and Blind Signature Schemes
2020Blind Signature is employed in privacy related protocols, where signer signs on a blinded message. It provides anonymity in various cryptographic applications such as electronic voting, digital cash system etc. Concerning the need for quantum resistant scheme, Ruckert and Tian et al.

A cryptographic system allows, in one exemplary use, a supplier (101) to cryptographically transform a plurality of messages responsive to secret keys; the transformed messages to be digitally signed by a signer (102); and the signed transformed messages returned to the supplier (101) to be transformed by the supplier (101), responsive to the same ...

An Efficient ID Based Proxy Signature, Proxy Blind Signature and Proxy Partial Blind Signature
2008 International Conference on Information Technology, 2008Identity-based (ID based) public key cryptosystem gives an efficient alternative for key management as compared to certificate based public key settings. A proxy signature is a method for an entity to delegate signing capabilities to other participants so that they can sign on behalf of the entity with in a given context.

On the Complexity of Blind Signatures
2010Blinde Signaturen ähneln einem Briefumschlag, der aus Kohlepapier besteht. Der Sig- nierer (Sender) unterschreibt dabei auf diesem Kohlepapier, ohne das im Briefumschlag liegende Dokument zu sehen. Danach erhält der Empfänger den Briefumschlag und somit die unterschriebene Nachricht.

Efficient Identity-Based Signatures and Blind Signatures
2005In this paper, we first propose an efficient provably secure identity-based signature (IBS) scheme based on bilinear pairings, then propose an efficient identity-based blind signature (IBBS) scheme based on our IBS scheme. Assuming the intractability of the Computational Diffie-Hellman Problem, our IBS scheme is unforgeable under adaptive chosen ...

Certificateless Partially Blind Signature
2012 26th International Conference on Advanced Information Networking and Applications Workshops, 2012Blind signatures play a central role in applications such as e-cash and e-voting systems, while partially blind signature is an even more applicable variant. This paper proposes a Certificate less Partially Blind Signature (CPBS) by laying its construction on bilinear pairings over Gap Diffie-Hellman (GDH) Group for solving the key escrow problem in ...

Boosting the Security of Blind Signature Schemes
2021Existing blind signature schemes that are secure for poly- nomially many concurrent executions of the signing protocol are either inefficient or rely on non-standard assumptions (even in the random-oracle model). We show the first efficient blind signature schemes achieving this level of security based on the RSA, factoring, or discrete-logarithm ...

Fair Partially Blind Signatures
2010It is well-known that blind signature schemes provide full anonymity for the receiving user. For many real-world applications, however, this leaves too much room for fraud. There are two generalizations of blind signature schemes that compensate this weakness: fair blind signatures and partially blind signatures.
