The field of neural cryptography explores innovative methods for secure key exchange by harnessing the synchronisation capabilities intrinsic to artificial neural networks. Unlike conventional ...

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 ...

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 ...

The old and insecure MD5 hashing function hasn’t been used to sign SSL/TLS server certificates in many years, but continues to be used in other parts of encrypted communications protocols, including ...

The Signal Foundation, maker of the Signal Protocol that encrypts messages sent by more than a billion people, has rolled out an update designed to prepare for a very real prospect that’s never far ...

Apple Inc. plans to update iMessage with a new encryption component, dubbed PQ3, that can block cyberattacks launched by quantum computers. Members of the company’s cybersecurity research team ...

In 2018, Aayush Jain, a graduate student at the University of California, Los Angeles, traveled to Japan to give a talk about a powerful cryptographic tool he and his colleagues were developing. As he ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...
