QUAD (cipher)

Index QUAD (cipher)

In cryptography, the QUAD, cipher is a relatively new stream cipher, which was designed with provable security arguments in mind. [1]

4 relations: Cryptography, Keystream, Security level, Stream cipher.

Keystream

In cryptography, a keystream is a stream of random or pseudorandom characters that are combined with a plaintext message to produce an encrypted message (the ciphertext).

Security level

In cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves.
