Final answer:
The symmetric algorithm approved in 2000 that is designed to be secure well into the future is the Advanced Encryption Standard (AES).
Step-by-step explanation:
The symmetric algorithm approved in 2000 that is designed to be secure well into the future is known as the Advanced Encryption Standard (AES). It was established by the U.S. National Institute of Standards and Technology (NIST) as a replacement for the older Data Encryption Standard (DES). AES is widely used in various applications such as securing wireless networks, encrypting data, and ensuring secure online transactions.
AES employs a block cipher technique where data is encrypted in fixed-size blocks, and it offers key sizes of 128, 192, or 256 bits. Due to its robust security features and flexibility, AES is expected to meet encryption needs for many years to come, and it is the de facto choice for numerous security applications across industries.
The symmetric algorithm approved in 2000 that is designed to be secure well into the future is Advanced Encryption Standard (AES).
AES is a widely used encryption algorithm that is employed by governments, organizations, and individuals to protect sensitive data. It is considered to be secure and has become the standard for data encryption.
The algorithm uses a fixed block size of 128 bits and supports key sizes of 128, 192, and 256 bits. It operates on a substitution-permutation network that involves several rounds of substitution, permutation, and mixing operations, which provide the security and confidentiality of the encrypted data.
