## Block cipher

In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called a block, with an unvarying transformation that is specified by a symmetric key.

## Block size (cryptography)

In modern cryptography, symmetric key ciphers are generally divided into stream ciphers and block ciphers.

## Bruce Schneier

Bruce Schneier (born January 15, 1963, is an American cryptographer, computer security professional, privacy specialist and writer. He is the author of several books on general security topics, computer security and cryptography. Schneier is a fellow at the Berkman Center for Internet & Society at Harvard Law School, a program fellow at the New America Foundation's Open Technology Institute. He has been working for IBM since they acquired Resilient Systems where Schneier was CTO. He is also a contributing writer for The Guardian news organization.

## Chosen-plaintext attack

A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts.

## Cipher

In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption&mdash;a series of well-defined steps that can be followed as a procedure.

## Computer hardware

Computer hardware includes the physical parts or components of a computer, such as the central processing unit, monitor, keyboard, computer data storage, graphic card, sound card and motherboard.

## Cryptanalysis

Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to loosen" or "to untie") is the study of analyzing information systems in order to study the hidden aspects of the systems.

## Cryptography

Cryptography or cryptology (from κρυπτός|translit.

## John Kelsey (cryptanalyst)

John Kelsey is a cryptographer who works at NIST.

## Key size

In cryptography, key size or key length is the number of bits in a key used by a cryptographic algorithm (such as a cipher).

## PostScript

PostScript (PS) is a page description language in the electronic publishing and desktop publishing business.

## Power of two

In mathematics, a power of two is a number of the form where is an integer, i.e. the result of exponentiation with number two as the base and integer as the exponent.

## Related-key attack

In cryptography, a related-key attack is any form of cryptanalysis where the attacker can observe the operation of a cipher under several different keys whose values are initially unknown, but where some mathematical relationship connecting the keys is known to the attacker.

Springer Science+Business Media or Springer, part of Springer Nature since 2015, is a global publishing company that publishes books, e-books and peer-reviewed journals in science, humanities, technical and medical (STM) publishing.

## Substitution–permutation network

In cryptography, an SP-network, or substitution–permutation network (SPN), is a series of linked mathematical operations used in block cipher algorithms such as AES (Rijndael), 3-Way, Kuznyechik, PRESENT, SAFER, SHARK, and Square.

## Word (computer architecture)
