This paperdescribesAES and Rijndael algorithm, a ciper suite based on the AES and Offset Codebook (OCB) mode, the implementation of AES inWLAN, and someattacks on the ciper AES.
To encrypt its data, the pen uses an algorithm called Rijndael, which the National Institute for Standards and Technology is planning to use as the Advanced Encryption Standard, which will replace the existing Data Encryption Standard (DES), which is currently being phased out of use.
