Card-based cryptographic protocols employ physical playing cards to facilitate secure multiparty computations without the need for electronic devices. These protocols allow participants to perform ...

Quantum computing represents an existential threat to modern cryptographic defenses, particularly for non-human identities—machines, IoT devices, workloads, applications, services and APIs—which rely ...

Internet security is a major concern, but cryptographic protocol analysis tools often require a long time due to their computational complexity. Professor Kazuhiro Ogata and Assistant Professor Canh ...

Apple today announced a new post-quantum cryptographic protocol for iMessage called PQ3. Apple says this "groundbreaking" and "state-of-the-art" protocol provides "extensive defenses against even ...

Quantum computers, machines that process information leveraging quantum mechanical effects, could outperform classical computers on some optimization tasks and computations. Despite their potential, ...

Parallelizing the backward narrowing at each layer in step (1) and the transition subsumption in step (2) significantly improves the runtime performance of Maude-NPA. The study reports speedups of 82% ...

For the first time, researchers have demonstrated that a large portion of cryptographic keys used to protect data in computer-to-server SSH traffic are vulnerable to complete compromise when naturally ...
