One-More Unforgeability of Blind ECDSA [PDF]

Lecture Notes in Computer Science, 2021
In this paper, we give the first formal security analysis on the one-more unforgeability of blind ECDSA. We start with giving a general attack on blind ECDSA, which is similar to the ROS attack on the blind Schnorr signature.

Some Thoughts on Strong Unforgeability in Ring Signature Schemes

Advanced Materials Research, 2012
A signature scheme is strongly unforgeable if the adversary cannot produce a new signature even on a queried message. Some methods have been proposed to enhance some regular signatures.

Attribute-Based Signcryption : Signer Privacy, Strong Unforgeability and IND-CCA2 Security in Adaptive-Predicates Attack [PDF]

Lecture Notes in Computer Science, 2014
An Attribute-Based Signcryption (ABSC) is a natural extension of Attribute-Based Encryption (ABE) and Attribute-Based Signature (ABS), where we have the message confidentiality and authenticity together.

One-More Unforgeability for Multi - and Threshold Signatures [PDF]

Lecture Notes in Computer Science
This paper initiates the study of one-more unforgeability for multi-signatures and threshold signatures as a stronger security goal, ensuring that ℓ executions of a signing protocol cannot result in more than ℓ signatures.

Strong existential unforgeability and BUFF securities of MPC-in-the-head signatures [PDF]

Designs, Codes, and Cryptography
NIST started the standardization of additional post-quantum signatures in 2022. Among 40 candidates, a few showed stronger security than existential unforgeability, strong existential unforgeability, and BUFF (beyond unforgeability features) securities ...

Bird of Prey: Practical Signature Combiners Preserving Strong Unforgeability

Lecture Notes in Computer Science
Following the announcement of the first winners of the NIST post-quantum cryptography standardization process in 2022, cryptographic protocols are now undergoing migration to the newly standardized schemes.

BUFFing signature schemes beyond unforgeability and the case of post-quantum signatures

, 2021
Modern digital signature schemes can provide more guarantees than the standard notion of(strong) unforgeability, such as offering security even in the presence of maliciously generated keys, or requiring to know a message to produce a signature for it ...
