What is the FIPS publication that specifies the Rijndael algorithm?

• A. FIPS 197
• B. FIPS 198
• C. FIPS 199
• D. FIPS 200

Answer: (A)

FIPS 197 is the publication that specifies the Rijndael algorithm, which is widely known as the Advanced Encryption Standard (AES). This standard was adopted by the National Institute of Standards and Technology (NIST) after a public competition to find a suitable replacement for the Data Encryption Standard (DES). The Rijndael algorithm, which was designed by Belgian cryptographers Joan Daemen and Vincent Rijmen, was selected because of its strong security capabilities and efficiency in processing. FIPS 197 details the technical specifications and requirements for implementing the Rijndael algorithm as a cryptographic standard for federal use. It outlines key aspects such as the algorithm's structure, its encryption and decryption processes, key sizes, and the block size, which ultimately provides a framework that ensures the protection of sensitive government data. The other FIPS publications mentioned do not pertain to the Rijndael algorithm. FIPS 198 deals with the HMAC (Hash-based Message Authentication Code) standard, FIPS 199 covers standards for security categorization of federal information and information systems, and FIPS 200 outlines minimum security requirements for federal information and information systems. Therefore, when looking for the publication that specifically describes the Rijndael algorithm, FIPS 197 is the
