This is a compact implementation of AES-256 in C. It uses only a byte type and is portable enough to fit even an 8-bit computer. It also has a small memory footprint because S-box operations use ...

I'd like to thank my co-author, Martin Zugec, for his valuable contributions to this report. This intrusion adds three dimensions to the public understanding of Chinese APT activity in contested ...

Secure communication is essential in modern embedded systems, particularly in distributed and IoT applications. This article presents a practical implementation of encrypted message exchange between ...

Key recovery attack on SPN ciphers such as AES is NP hard in complexity. Previous studies have estimated the quantum resources required for implementing Grover’s key search for AES, but these are ...

We describe the foundation of PETRIC, an image reconstruction challenge to minimise the computational runtime of related algorithms for Positron Emission Tomography (PET). Although several similar ...

Implementation of ITU-R BS.1770-4. Allows control over gating block size and frequency weighting filters for additional control. For full details on the implementation see our paper with a summary in ...

This week I audited three enterprise systems. All three claimed "AES-256 encryption for data at rest." All three were broken. Two used ECB mode (preserves patterns—completely broken for anything but ...

This paper explores the evolving landscape of data security in artificial intelligence (AI) environments and provides practical guidance aligned with the Cloud Security Alliance (CSA) AI Controls ...

Safety of medical products including drugs, vaccines, therapeutic biologics and medical devices is an important public health consideration globally. Adverse events associated with medical products ...

AI agents used in e-commerce necessitates secure payment protocols capable of handling high-determinism user authorization, agent authentication, and non-repudiable accountability. The Agent Payments ...
