Advanced Encryption Standard (AES) is a gold-standard data encryption algorithm. This question-and-answer guide answers frequently asked questions about AES and covers all the important aspects of this standard. AES was developed to replace the Data Encryption Standard (DES), which was susceptible to brute-force attacks. It is a major step toward a more secure digital economy that will create new opportunities for all Americans.
The AES algorithm was created by Morris Dworkin, Elaine Barker, James Nechvatal, Lawrence Bassam, Edward Roback, and James Dray Jr. It was adopted by the U.S. government in 2002 and is considered to be the most secure encryption algorithm. AES is also derived from the Rijndael family of encryption algorithms. It is asymmetric encryption algorithm, which means that it is not vulnerable to brute-force attacks.
