Generic Universal Forgery Attack on Iterative Hash-Based MACs [PDF]

Lecture Notes in Computer Science, 2014
In this article, we study the security of iterative hash-based MACs, such as HMAC or NMAC, with regards to universal forgery attacks. Leveraging recent advances in the analysis of functional graphs built from the iteration of HMAC or NMAC, we exhibit the very first generic universal forgery attack against hash-based MACs.

Universal Forgery and Key Recovery Attacks on ELmD Authenticated Encryption Algorithm [PDF]

Lecture Notes in Computer Science, 2016
In this paper, we provide a security analysis of ELmD: a block cipher based Encrypt-Linear-mix-Decrypt authentication mode. As being one of the second-round CAESAR candidate, it is claimed to provide misuse resistant against forgeries and security against block-wise adaptive adversaries as well as 128-bit security against key recovery attacks.

A deep multimodal system for provenance filtering with universal forgery detection and localization [PDF]

Multimedia Tools and Applications, 2020
[EN] Traditional multimedia forensics techniques inspect images to identify, localize forged regions and estimate forgery methods that have been applied. Provenance filtering is the research area that has been evolved recently to retrieve all the images that are involved in constructing a morphed image in order to analyze an image, completely ...

Cryptanalyses on a Merkle-Damgård Based MAC — Almost Universal Forgery and Distinguishing-H Attacks [PDF]

Lecture Notes in Computer Science, 2012
This paper presents two types of cryptanalysis on a Merkle-Damgard hash based MAC, which computes a MAC value of a message M by Hash(K||l||M) with a shared key K and the message length l. This construction is often called LPMAC. Firstly, we present a distinguishing-H attack against LPMAC instantiating any narrow-pipe Merkle-Damgard hash function with O(
