Term Description
Advanced Encryption Standard
The Advanced Encryption Standard (AES) is a specification for the encryption of electronic data
established by the U.S. National Institute of Standards and Technology (NIST).
AES is based on a design principle known as a substitution-permutation network, and is fast in both
software and hardware. Unlike its predecessor DES, AES does not use a Feistel network. AES is a
variant of Rijndael which has a fixed block size of 128 bits,
AES
The key size used for an AES cipher specifies tVersion: A.7he number of repetitions of transformation
rounds that convert the input, called the plaintext, into the final output, called the ciphertext. The
number of cycles of repetition are as follows:
10 cycles of repetition for 128-bit keys.
12 cycles of repetition for 192-bit keys.
14 cycles of repetition for 256-bit keys.

Data Encryption Standard
DES is a widely-used method of data encryption using a private (secret) key that was judged so
difficult to break by the U.S. government that it was restricted for exportation to other countries. For
each given message, the key is chosen at random from among this enormous number of keys. Like
other private key cryptographic methods, both the sender and the receiver must know and use the
DES
same private key.
DES applies a 56-bit key to each 64-bit block of data. The process can run in several modes and
involves 16 rounds or operations. Although this is considered "strong" encryption, many companies use
"triple DES", which applies three keys in succession.
