Description: The Advanced Encryption Standards (AES) is a Federal Information Processing Standards Publications (FIPS)-approved cryptographic algorithm that protects electronic data. The AES algorithm is a symmetric block cipher that can encrypt and decrypt information. This means that the same key is used for both encrypting and decrypting the data. Encryption converts the data into an unintelligible form called ciphertext, whereas decrypting the data converts the ciphertext back into its original form called plaintext. The algorithm can use cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
