Which encryption standard is based on the Rijndael block cipher algorithm?

• A. Advanced Encryption Standard (AES)
• B. Adware
• C. Address Resolution Protocol (ARP)
• D. Anti-Virus Software

Answer: (A)

Rijndael was chosen as the algorithm for the Advanced Encryption Standard. The AES standard is essentially Rijndael standardized by NIST after a competitive process, making it the official, widely adopted encryption standard. AES uses a fixed block size of 128 bits and supports key lengths of 128, 192, or 256 bits, which gives strong security and versatility for protecting data. The other options aren’t encryption standards: adware is unwanted software that displays ads, ARP is the protocol that maps IP addresses to MAC addresses on a local network, and anti-virus software is for detecting and removing malware. So the standard based on Rijndael is AES.
