![]() ![]() ![]() Triple DES is specified in SP 800-67 Revision 2, Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher, which was approved in November 2017. The AES Development details have been archived. Government organizations (and others) to protect sensitive information. This standard specifies the Rijndael algorithm as a FIPS-approved symmetric-key algorithm that may be used by U.S. NIST announced the approval of FIPS 197, Advanced Encryption Standard in 2001. AES must be used with the modes of operation designed specifically for use with block cipher algorithms. Advanced Encryption Standard (AES)ĪES is specified in FIPS 197, Advanced Encryption Standard (AES), which was approved in November 2001. 1, Transitions: Recommendation for Transitioning the Use of Cryptographic Algorithms and Key Lengths, for additional information about the use of these block cipher algorithms.įederal agencies should see OMB guidance about the use of strong encryption algorithms and OMB Memorandum 07-16, item C about the use of NIST certified cryptographic modules. See the discussions below for further information also see SP 800-131A Rev. Two (2) other block cipher algorithms were previously approved: DES and Skipjack however, their approval has been withdrawn. Currently, there are two (2) Approved * block cipher algorithms that can be used for both applying cryptographic protection (e.g., encryption) and removing or verifying the protection that was previously applied (e.g., decryption): AES and Triple DES. ![]()
