NIST announces the completion of revisions of Special Publication (SP) 800-67, Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher, and SP 800-90A, Recommendation for Random Number Generation Using Deterministic Random Bit Generators. Both publications are available at
http://csrc.nist.gov/publications/PubsSPs.html . SP 800-67 specifies the Triple Data Encryption Algorithm (TDEA) block cipher, which includes a Data Encryption Algorithm (DEA) cryptographic engine that is implemented as a component of TDEA. SP 800-90A specifies mechanisms for the generation of random bits using deterministic methods. The methods provided are based on either hash functions, block cipher algorithms or number theoretic problems.
