X-band SAR satellites (8-12 GHz) play a critical role in disaster response, environmental monitoring, and military intelligence. Yet, they lack robust physical-layer authentication (PLA), a security layer orthogonal to cryptographic solutions. Existing PLA systems, typically based on radio-frequency fingerprinting, are...

The security twin (ST) paradigm is an emerging framework for dynamically modeling and defending complex cyber-physical systems. This paper extends NotLine, a fully automated, non-intrusive ST construction platform with three mechanisms. First, a lightweight statistical engine based on the numerically stable Welford alg...
Large Language Model (LLM) agents are increasingly deployed as populations of interacting entities, in which consensus --agreement on a shared answer-- emerges as a collective, unengineered behaviour. Prior work on LLM consensus shows that agents can cross-verify their answers and converge towards more factual response...
