MALRIS: Malicious Hardware in RIS-Assisted Wireless Communications

Reconfigurable intelligent surfaces RIS enhance wireless communication by dynamically shaping the propagation environment, but their integration introduces hardware-level security risks. This paper presents the concept of Malicious RIS MALRIS, where compromised components behave adversarially, ev...

Active Attack Resilience in 5G: a New Take on Authentication and Key Agreement

As 5G networks expand into critical infrastructure, secure and efficient user authentication is more important than ever. The 5G-AKA protocol, standardized by 3GPP in TS 33.501, is central to authentication in current 5G deployments. It provides mutual authentication, user privacy, and key secrec...

Sparse Regression Codes for Secret Key Agreement: Achieving Strong Secrecy and Near-Optimal Rates for Gaussian Sources

Secret key agreement from correlated physical layer observations is a cornerstone of information-theoretic security. This paper proposes and rigorously analyzes a complete, constructive protocol for secret key agreement from Gaussian sources using Sparse Regression Codes SPARCs. Our protocol...

LLM Meets the Sky: Heuristic Multi-Agent Reinforcement Learning for Secure Heterogeneous UAV Networks

This work tackles the physical layer security PLS problem of maximizing the secrecy rate in heterogeneous UAV networks HetUAVNs under propulsion energy constraints. Unlike prior studies that assume uniform UAV capabilities or overlook energy-security trade-offs, we consider a realistic scenario...

Secure Wireless Communication Via Polarforming

Polarforming is a promising technique that enables dynamic adjustment of antenna polarization to mitigate depolarization effects commonly encountered during electromagnetic EM wave propagation. In this letter, we investigate the polarforming design for secure wireless communication systems, where...

Fairness-Aware Secure Integrated Sensing and Communications with Fractional Programming

We propose a novel secure integrated sensing and communications ISAC system designed to serve multiple communication users CUs and targets. To that end, we formulate an optimization problem that maximizes the secrecy rate under constraints balancing both communication and sensing requirements. To...

On the Virtues of Information Security in the UK Climate Movement

We report on an ethnographic study with members of the climate movement in the United Kingdom UK. We conducted participant observation and interviews at protests and in various activist settings. Reporting on the findings as they relate to information security, we show that members of the UK...

CVE-2022-45195

SimpleXMQ before 3.4.0, as used in SimpleX Chat before 4.2, does not apply a key derivation function to intended data, which can interfere with forward secrecy and can have other impacts if there is a compromise of a single private key. This occurs in the X3DH key exchange for the double ratchet...

On the Vulnerability of Underwater Magnetic Induction Communication

Typical magnetic induction MI communication is commonly considered a secure underwater wireless communication UWC technology due to its non-audible and non-visible nature compared to acoustic and optical UWC technologies. However, vulnerabilities in communication systems inevitably exist and may...

The vulnerability of the sub_422eb8 function in Linksys E8450 Wi-Fi routers allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the sub422eb8 function in Linksys E8450 Wi-Fi routers’ microprogramming software is related to the copying of buffers without checking the size of the input data. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity, and accessibili...

AI Industry is Trying to Subvert the Definition of “Open Source AI”

The Open Source Initiative has published news article here its definition of "open source AI," and it's terrible. It allows for secret training data and mechanisms. It allows for development to be done in secret. Since for a neural network, the training data is the source code--it's how the model...

Did a Chinese University Hacking Competition Target a Real Victim?
