On blind signatures and perfect crimes

Computers and Security, 1992
David Chaum has introduced the idea of blind signatures, an extension of the concept of digital signatures, as a way to protect the identity and privacy of a user in electronic payment and service networks. Blind signatures also prevent so-called ''dossier creation'' about users by organizations.

Efficient Lattice-Based Blind Signatures via Gaussian One-Time Signatures [PDF]

Lecture Notes in Computer Science, 2022
Lattice-based blind signature schemes have been receiving some recent attention lately. Earlier efficient 3-round schemes (Asiacrypt 2010, Financial Cryptography 2020) were recently shown to have mistakes in their proofs, and fixing them turned out to be

ID-based restrictive partially blind signatures and applications [PDF]

Journal of Systems and Software, 2007
. Restrictive blind signatures allow a recipient to receive a blind signature on a message not known to the signer but the choice of message is restricted and must conform to certain rules.

Non-interactive Blind Signatures for Random Messages [PDF]

Lecture Notes in Computer Science, 2023
Blind signatures allow a signer to issue signatures on messages chosen by the signature recipient. The main property is that the recipient\u27s message is hidden from the signer. There are many applications, including Chaum\u27s e-cash system and Privacy

On the security of blind signature and partially blind signature

2010 2nd International Conference on Education Technology and Computer, 2010
Blind signature allows a user to obtain a signature from an authority on any document, in such a way that the authority learns nothing about the message that is being signed. The blindness is an important property which distinguishes the blind signature from other signature schemes.

Security Arguments for Digital Signatures and Blind Signatures

Journal of Cryptology, 2000
This paper proves the security of a large class of signature schemes in the so-called random oracle model. This model assumes that the hash function used in a signature scheme behaves as a random function. However, it has been shown that there exist (contrived) schemes that are provably secure in the random oracle model, but not when used with a real ...

Certificateless signature and blind signature

Journal of Electronics (China), 2008
Certificateless public key cryptography is a new paradigm introduced by Al-Riyami and Paterson. It eliminates the need of the certificates in traditional public key cryptosystems and the key escrow problem in IDentity-based Public Key Cryptography (ID-PKC).

Rerandomizable Threshold Blind Signatures

2015
This paper formalizes the concept of threshold blind signatures (TBS) that bridges together properties of the two well-known signature flavors, blind signatures and threshold signatures. Using TBS users can obtain signatures through interaction with t-out-of-n signers without disclosing the corresponding message to any of them.

Untraceability of Partial Blind and Blind Signature Schemes

2020
Blind 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.
