Universal Forgery Attack Against GCM-RUP [PDF]
, 2020 Authenticated encryption (AE) schemes are widely used to secure communications because they can guarantee both confidentiality and authenticity of a message. In addition to the standard AE security notion, some recent schemes offer extra robustness, i.e. they maintain security in some misuse scenarios. In particular, Ashur, Dunkelman and Luykx proposed

A Large-scale Universal Evaluation Benchmark For Face Forgery Detection
CoRRWith the rapid development of AI-generated content (AIGC) technology, the production of realistic fake facial images and videos that deceive human visual perception has become possible. Consequently, various face forgery detection techniques have been proposed to identify such fake facial content.

The power of primes: security of authentication based on a universal hash-function family
Journal of Mathematical Cryptology, 2010 Message authentication codes (MACs) based on universal hash-function families are becoming increasingly popular due to their fast implementation. In this paper, we investigate a family of universal hash functions that has been appeared repeatedly in the ...

Self-Supervised Feature Disentanglement for Deepfake Detection
MathematicsExisting deepfake detection methods heavily rely on specific training data distributions and struggle to generalize to unknown forgery techniques. To address the challenge, this paper focuses on two critical research gaps: (1) the lack of systematic ...

Kahrobaei--Koupparis DSS: universal forgery [PDF]
journal of Groups, complexity, cryptology<div><p>Regardless of the choice of parameters, knowledge of a single signed message, i.e., a pair message/signature, produced by Kahrobaei-Koupparis digital signature scheme, proposed in [D. Kahrobaei and C. Koupparis, 2012], is sufficient to forge a valid signature for any other message.

Forgery of artists’ signatures on paintings or print from the perspective of Polish law
Studia Prawnicze KUL, 2023 The protection granted by law to art buyers ensures safe trade and confidence in the art market. It is also a crucial factor whenever a purchased piece turns out to be a forgery. Having a single legal act instead of various provisions spread across many

On Protecting SPHINCS+ Against Fault Attacks
Transactions on Cryptographic Hardware and Embedded Systems, 2023 SPHINCS+ is a hash-based digital signature scheme that was selected by NIST in their post-quantum cryptography standardization process. The establishment of a universal forgery on the seminal scheme SPHINCS was shown to be feasible in practice by ...

Fuzzy Based Image Forensic Tool for Detection and Classification of Image Cloning
International Journal of Computational Intelligence Systems, 2016 With the easy availability of image processing and image editing tools, the cases of forgery have been raised in the last few years. Now days it is very difficult for a viewer and judicial authorities to verify authenticate a digital image.
