Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher
Date Published: July 2017
Email Questions to:
This draft is intended to supersede SP 800-67 Revision 1, which limits the TDEA block cipher to apply the cryptographic protection (e.g., encrypt) to 232 64-bit blocks under one key bundle. The draft SP 800-67 Revision 2 further lowers this limit to 220 64-bit data blocks per key bundle, following the announcement by NIST to update its guidance on the current use of TDEA.
