A team of three researchers has resolved one of the longest-standing open problems in post-quantum cryptography, publishing the first-ever construction of identity-based encryption (IBE) grounded ...
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 ...
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 ...
