Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

The National Security Agency (NSA) is offering two families of encryption algorithms, known as block ciphers, intended to provide a level of security for such processes as authentication or ...

The arena of creating secure environments in the hardware and software industries is somewhat shrouded in mystery and misunderstanding. Certainly, some types of ciphers are relatively straightforward ...

Data Encryption Standard and Advanced Encryption Standard sound similar, and both are examples of symmetric block ciphers. That is where the similarities end, however. DES is an outdated method of ...

- Japan's only 128-bit block cipher encryption algorithm to be adopted - TOKYO--(BUSINESS WIRE)-- Nippon Telegraph and Telephone Corporation (NYS: NTT) and Mitsubishi Electric Corporation (TOKYO:6503) ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...
