Robust Copy-Move Forgery Detection Technique Against Image Degradation and Geometric Distortion Attacks [PDF]
<p>The rapid pace of the digital age has led to an increase in the illegal copying, reproduction, and creation of forgeries of digital images. Copy-move forgery is one of the most common image forgery techniques which is used for tampering with ...

On Beyond-Birthday-Bound Security: Revisiting the Development of ISO/IEC 9797-1 MACs
ISO/IEC 9797-1 is an international standard for block-cipher-based Message Authentication Code (MAC). The current version ISO/IEC 9797-1:2011 specifies six single-pass CBC-like MAC structures that are capped at the birthday bound security.

Security of COFB against Chosen Ciphertext Attacks
COFB is a lightweight Authenticated Encryption with Associated Data (AEAD) mode based on block ciphers. It was proposed in CHES 2017 and is the basis for GIFT-COFB, a finalist in the NIST lightweight standardization project.

CoMoFoD #x2014; New database for copy-move forgery detection [PDF]
Due to the availability of many sophisticated image processing tools, a digital image forgery is nowadays very often used. One of the common forgery method is a copy-move forgery, where part of an image is copied to another location in the same image ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

While cysteine is widely employed as a nucleophilic handle for peptide modification, the electrophilicity of the oxidized form, cystine, is rarely exploited. This study describes a mild, photochemical coupling of sulfinate salts with peptide disulfides.

Key Recovery and Forgery Attacks on the MacDES MAC Algorithm [PDF]
We describe a series of new attacks on a CBC-MAC algorithm due to Knudsen and Preneel including two key recovery attacks and a forgery attack. Unlike previous attacks, these techniques will work when the MAC calculation involves prefixing the data to be MACed with a 'length block'. These attack methods provide new (tighter) upper bounds on the level of

Programmable luminescent tags based on organic room‐temperature phosphorescence are shown to be governed by oxygen incorporation during fabrication. Oxygen‐free processing enables immediate phosphorescence activation, controlled thermal preconditioning, and tunable activation doses.
