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 ...

Apple says testing missed flaws in new encryption designed to protect against future attacks from quantum computers, so it turned to mathematical proofs to make sure the code works correctly before ...

Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them ...

Beyond advanced mathematics or theoretical computing breakthroughs, PQC is about protecting the systems enterprises already depend on to operate securely at scale.

Encryption is one of several cornerstones of a robust information security program. Articles on quantum computing often include the compelling narrative that encryption is at risk, but as with any ...

Two brothers in Singapore have built a data-encryption company on pure mathematics, betting that a problem no algorithm can solve will keep files safe from the quantum computers expected to break much ...
