Anthropic’s Mythos AI model has helped discover two new cryptanalytic attacks, one against the NIST post-quantum digital ...
Anthropic says its Claude Mythos Preview model has found new flaws in AES encryption, the cipher protecting online banking, ...
Introduction to ciphers and substitution. Alice and Bob and Carl and Julius: terminology and Caesar Cipher ; The key to the matter: generalizing the Caesar Cipher ; Multiplicative ciphers ; Affine ...
In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and ...
In my blog “The Importance of Memory Encryption for Protecting Data in Use,” I discussed the growing industry consensus on the imperative of incorporating memory encryption in computing architectures.
What do the Gallic Wars and online shopping have in common? The answer, believe it or not, is cryptography. Cryptography is the cement of the digital world, but it also has a long history that ...
