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 ...

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional ...

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 ...

This course covers the basic knowledge in understanding and using cryptography. The main focus is on definitions, theoretical foundations, and rigorous proofs of security, with some programming ...

Woodcliff Lake, New Jersey — September 30, 2025 — Semiconductor intellectual property (IP) provider CAST today announced the availability of a new SM4 Cipher IP Core, delivering compact, ...

An encryption method that works with continuous streams of input rather than fixed blocks. Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an ...
