WebNov 14, 2024 · The federal government originally developed DES encryption over 35 years ago to provide cryptographic security for all government communications. The idea was to ensure government systems all used the same, secure standard to facilitate interconnectivity. Why DES is no longer effective WebNov 26, 2001 · National Institute of Standards and Technology Abstract The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information.

Currently, AES is one of only two block cipher standards that are approved by NIST. The other block cipher standard is the Triple Data Encryption Algorithm (TDEA) [4] software firewall vs hardware firewall
