XDRGB – Random Bit Generator using any XOF
Resulting from a joint collaboration between John Kelsey (NIST), Stefan Lucks (Bauhaus-Universität Weimar, Germany) and Stephan Müller (atsec information security), a new deterministic random bit generator (DRBG) is published. The XDRBG was publicly presented at the 30th Fast Software Encryption Conference 2024 in Leuven, Belgium. The XDRBG uses…

First Post-Quantum Algorithm Certificate issued by CAVP3
On July 14, atsec obtained the first validation certificate for a post-quantum cryptographic algorithm: A4204. We used the Automated Cryptographic Validation Protocol (ACVP) to verify the correctness of the LMS (Leighton-Micali Signature) key pair generation, signature generation, and signature verification implementations in the QASM Hardware Security Module, developed…

Distinguishing encrypted from non-encrypted data
Our colleague Quentin Gouchet, together with Eric Järpe, authored an article on distinguishing encrypted from non-encrypted data. We invite you to read the article here. Introduction:The discrimination of encrypted data from other kinds of data is of interest in many areas of application. For instance for making other…
