Final answer:
NIST recommends the Advanced Encryption Standard (AES) for encryption, which supersedes the older Data Encryption Standard (DES) due to its enhanced security and efficiency.
Step-by-step explanation:
The United States National Institute of Standards and Technology (NIST) recommends the Advanced Encryption Standard (AES) for encryption. AES is widely used across the globe to secure sensitive data and is known for its strong security and fast encryption capabilities. It has replaced the older Data Encryption Standard (DES), which was found to be less secure. RSA and ECC (Elliptic Curve Cryptography) are other forms of encryption, with RSA being an asymmetric algorithm predominantly used for secure data transmission and ECC known for smaller key sizes and efficiency, but for the purpose of encryption AES is the recommended standard by NIST.
