Scope
This Technical Report provides the user with technical support and details for the safe and efficient
implementation of the Triple Data Encryption Algorithm (TDEA) modes of operation for the enhanced
cryptographic protection of digital data. The modes of operation described herein are specified for both
enciphering and deciphering operations. The modes described in this Technical Report are implementations
of the block cipher modes of operation specified in ISO/IEC 10116 using the Triple DEA algorithm (TDEA)
specified in ISO/IEC 18033-3.
The TDEA modes of operation may be used in both wholesale and retail financial applications. The use of this
Technical Report provides the basis for the interoperability of products and facilitates the development of
application standards that use the TDEA modes of operation. This Technical Report is intended for use with
other ISO standards using DEA.
