Advanced Encryption Standard

(cryptography, algorithm)
(AES) The NIST's replacement for the Data Encryption Standard (DES). The Rijndael /rayn-dahl/ symmetric block cipher, designed by Joan Daemen and Vincent Rijmen, was chosen by a NIST contest to be AES.

AES is Federal Information Processing Standard FIPS-197.

AES currently supports 128, 192 and 256-bit keys and encryption blocks, but may be extended in multiples of 32 bits.

(Advanced Encryption Standard) A U.S. government encryption standard supported by the National Institute of Standards & Technology (NIST). AES is a cryptographic cipher that uses a block length of 128 bits and key lengths of 128, 192 or 256 bits. Officially replacing the Triple DES method in 2001, AES uses the Rijndael algorithm developed by Joan Daemen and Vincent Rijmen of Belgium. AES can be encrypted in one pass instead of three, and its key size is greater than Triple DES's 168 bits. In early 1997, the NIST invited cryptographers to submit an advanced algorithm. In late 2000, the Rijndael (pronounced "rine-doll") symmetric block cipher algorithm was selected out of submissions by 21 teams from 11 countries. See cipher, cryptography, NIST, DES and AES/CCMP.

It can demodulate four transponders from four RF inputs, with up to 64 MBaud bandwidth, while fixed-key AES-128 and BISS-descrambling are embedded into both the modulator and demodulator.
The IQRF currently has the following main parameters [14]: (i) unlicensed wireless radio technology (supporting frequencies 868 MHz, 916 MHz and 433 MHz); (ii) P2P or MESH topology; (iii) ultra-low-power (sleep mode--hundreds of nA; transmission--based on mode, average hundreds of [mu]A); (iv) low throughput (19.836 kb/s or 19.2 kb/s); (v) byte oriented protocol DPA for services and peripherals control; (vi) low to medium range (considering small antennas--tens of meters in buildings, hundreds of meters in open space); (vii) security (nodes are bound to the network via password, network encryption via AES-128 with self-distribution of the keys, optional user encryption via AES-128, message checksum CRC-16, and block checksums).
For some, the information also includes payment card numbers and payment card expiration dates, but the payment card numbers were encrypted using Advanced Encryption Standard encryption, or AES-128. There are two components needed to decrypt the payment card numbers, and at this point, Marriott has not been able to rule out the possibility that both were taken.
In this configuration CTR was used to encrypt the data using AES-128, and CBCMAC was constructed using AES-128 as well.

If this was not possible, AES-128 keys were used to encrypt each individual file, with the AES keys subsequently being encrypted using an RSA-2048 public key.
