A Highly Accurate Query-Recovery Attack against Searchable Encryption using Non-Indexed Documents
Cloud data storage solutions offer customers cost-effective and reduced data management. While attractive, data security issues remain to be a core concern. Traditional encryption protects stored...
Passive Query-Recovery Attack Against Secure Conjunctive Keyword Search Schemes
While storing documents on the cloud can be attractive, the question remains whether cloud providers can be trusted with storing private documents. Even if trusted, data breaches are ubiquitous....
Obfuscated Access and Search Patterns in Searchable Encryption
Searchable Symmetric Encryption (SSE) allows a data owner to securely outsource its encrypted data to a cloud server while maintaining the ability to search over it and retrieve matched documents....
Automated Retrieval of ATT&CK Tactics and Techniques for Cyber Threat Reports
Over the last years, threat intelligence sharing has steadily grown, leading cybersecurity professionals to access increasingly larger amounts of heterogeneous data. Among those, cyber attacks'...
Identifying Near-Optimal Single-Shot Attacks on ICSs with Limited Process Knowledge
Industrial Control Systems (ICSs) rely on insecure protocols and devices to monitor and operate critical infrastructure. Prior work has demonstrated that powerful attackers with detailed system...
Biometric Verification Secure Against Malicious Adversaries
Biometric verification has been widely deployed in current authentication solutions as it proves the physical presence of individuals. To protect the sensitive biometric data in such systems,...
Introducing the Robot Security Framework (RSF), a standardized methodology to perform security assessments in robotics
Robots have gained relevance in society, increasingly performing critical tasks. Nonetheless, robot security is being underestimated. Robotics security is a complex landscape, which often requires...
Fast and Accurate Likelihood Ratio Based Biometric Comparison in the Encrypted Domain
As applications of biometric verification proliferate, users become more vulnerable to privacy infringement. Biometric data is very privacy sensitive as it may contain information as gender,...
General Impossibility of Group Homomorphic Encryption in the Quantum World
Group homomorphic encryption represents one of the most important building blocks in modern cryptography. It forms the basis of widely-used, more sophisticated primitives, such as CCA2-secure...
