Abstract

[Superseded by SP 800-67 Rev. 1 (January 2012): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=910079] The selective application of technological and related procedural safeguards is an important responsibility of every Federal organization in providing adequate security to its electronic data systems. This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, the Data Encryption Algorithm (DEA). When implemented in an SP 800-38 series-compliant mode of operation and in a FIPS 140-2 compliant cryptographic module, TDEA may be used by Federal organizations to protect sensitive unclassified data. Protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data. This recommendation precisely defines the mathematical steps required to cryptographically protect data using TDEA and to subsequently process such protected data. The Triple Data Encryption Algorithm (TDEA) is made available for use by Federal agencies within the context of a total security program consisting of physical security procedures, good information management practices, and computer system/network access controls.
