This standard is based on ISO /T R19038.2005 redrafted with ISO /T R19038.2005 technical differences are as follows. a) The standard "TDEA" According to China habits changed to "Triple Data Encryption Algorithm" (referred to as the "3-DEA" herein) (superscript Quasi-body part of the need to distinguish between reservations "triple DEA" argument); b) To facilitate the user's understanding of the standard text, add a term. "error propagation" (see 3.20); c) 5.5 for unnumbered, untitled Table number. Table 1DEA function block execution schedule, the following table No. postponed. d) in 6.6.1.1, the 7.4 TCFB with only difference is fed back to the data block shift function is not Oi Ci " Amended to read "and 6.4 TCFB only difference is fed back to the data block shift function is not Oi Ci" (errata); e) For ease of understanding, B.3.2 title in the "streamcipher" translated as "pseudo-random sequence of vectors {Oi}". For ease of use, this standard also made the following editorial changes. a) the original text of the "technical report" to the "standard"; b) Delete ISO /T R19038.2005 Foreword by modifying the ISO /T R19038. Introduction 2005. This standard Annex A, Annex B, Annex C is informative appendix. The standard proposed by the People's Bank of China.

Participated in the drafting of this standard. People's Bank of China, Industrial and Commercial Bank of China, Bank of China, Bank of Communications, China UnionPay Co., North China Institute of Computing Technology, Beijing Technology and Business University, Taiyuan Central Branch of People's Bank of China.

Since the 3-DEA operation mode can be backward compatible with existing DEA mode of operation, financial institutions can use 3-DEA extended Long DEA safety lifecycle investment protection standard DEA technology. Each operating mode has its advantages and characteristics. Selection of a particular mode of operation, implementation and use depends on the security to financial institutions Seeking, risk acceptance and operational requirements, which are not within the scope of this standard. If participants use the same mode of operation and shared secret secret Key, then the need to use this standard as defined herein 3-DEA operation mode according to the parties to provide the basis for interoperability. This standard does not replace the standard 3-DEA DEA algorithm algorithm and ISO /IEC 18033 as specified. DEA is a 3-DEA operation mode Type foundation. 3-DEA uses advanced computing technology and cryptanalysis techniques, provides greater security. 3-DEA available hardware, Software, or a hybrid implementation. This standard provides implementation guidance ISO /IEC 10116 in the specified operating mode. Financial institutions have a responsibility to establish a comprehensive security process that includes the necessary control measures to ensure that the above process in a secure way real Shi, and respond to audit the implementation process to confirm that the process of compliance with safety procedures. Banking and related financial services Triple Data Encryption Algorithm Operation mode Implementation Guide1 ScopeThis standard provides the user with the enhanced data encryption and secure effective implementation of the technical support 3-DEA operation mode and details data. The mode of operation of the 3-DEA operation described for the encryption and decryption operations. The standard mode is described using ISO /IEC 18033-3 specified in the block cipher mode of operation to achieve (in ISO /IEC 10116 as specified) of 3-DEA operation. 3-DEA operation mode can be used to finance wholesale and retail financial services applications. This standard enables interoperability and products With 3-DEA operation mode of application of standards development provides the foundation. The standard will use DEA and other ISO standards used together.2 Normative referencesThe following documents for the application of this document is essential.

Block operator3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 Birthday phenomenon birthdayphenomenon There are a relatively small group of n members of at least two people may have a common phenomenon birthday. Example. When n = 23, the probability of more than 1/2. If a person from the m digital alternative to each other may randomly pick one of the subjects in the n p = 1-En ^ 2/2m In the above experiments, the expected number of trials before the same value was found to be approximately (πm/2) 1/2. Which indicates that the use of hybrid key 64-bit block encryption operation, if a person owns 232 plaintext/ciphertext pairs and 232 generated by the random input ciphertext block of text dictionary, It should be considered an unknown cipher text block will be searched from the dictionary (see Ref. [11]). 3.2 Block; grouping block Binary string binarystring Example. divided into a given length of plaintext or ciphertext, each fragment is called a block (packet). Plaintext (ciphertext) from left to right by-block encryption (decryption). In the present Standard, for TCBC, TCBC-I, TOFB and TOFB-I \u200b\u200bmode, plaintext and ciphertext is divided into 64-bit block, but for TCFB and TCFB-P mode, It supports an 8-bit and 64-bit plaintext message and to encrypt and decrypt ciphertext block. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 27927-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 27927-2011_English as soon as possible, and keep you informed of the progress.
