Foreword

GB/T 15852 "Information Technology Security Technology Message Authentication Code" is divided into the following three parts. --- Part 1. The mechanism of using block ciphers; --- Part 2. Mechanisms using dedicated hash functions; --- Part 3. The mechanism of using a ubiquitous function. This part is the third part of GB/T 15852. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This section uses the redrafting method to modify the use of ISO /IEC 9797-3.2011 "Information Technology Security Technology Message Authentication Code No. 3 Part. The mechanism of using a general hash function. This section has a structural change compared to ISO /IEC 9797-3.2011, adjusting 6.3.3.1 to 6.3.3 and 6.5.3.1 to 6.5.3. The main technical differences between this part and ISO /IEC 9797-3.2011 and their reasons are as follows. ---About the normative reference documents, this part has made technical adjustments to adapt to China's technical conditions, adjustments The situation is reflected in Chapter 2, “Regulatory Citations”, and the specific adjustments are as follows. ● Replace ISO /IEC 9797-1 with GB/T 15852.1-2008 equivalent to the international standard; ● Removed ISO /IEC 18031, ISO /IEC 18033-3, ISO /IEC 18033-4; ● Added GB/T 32907-2016, GB/T 33133.1-2016, GB/T 36624-2018. --- In Chapter 3, two general terms and definitions of keys and prime numbers have been removed. --- Add abbreviations in Chapter 4. --- In 6.3.1, according to the ZUC algorithm's requirement for the initial vector, the Badger's 64-bit all-one initial vector is modified to 128 bits. All 1 initial vector. --- Remove the canonical Appendix A object identifier (because the lack of a domestic related object identifier definition). This section has made the following editorial changes. ---Adjustment of informative Appendix B is informative Appendix A, listing the MAC algorithm based on the ZUC or SM4 algorithm at the bottom. Test vector ---Adjustment of informative Appendix C is informative Appendix B, introducing the security information of the general hash function; --- Increase the informative Appendix C, introducing the anti-attack capabilities of the ZUC and SM4 algorithms.

1 Scope

This part of GB/T 15852 specifies four message authentication code algorithms using the ubiquitous function. UMAC, Badger, Poly1305 And GMAC. These algorithms are based on the sequence cipher algorithm specified in GB/T 33133.1-2016 and the provisions of GB/T 32907-2016. a block cipher algorithm, or other sequence cipher algorithm and block cipher algorithm that conforms to national regulations, using a key and a general hash function The number is processed into a bit string of length m bits, and a bit string of length n bits is output as a MAC. This section applies to security services for security architectures, processes, and applications. These algorithms can be used as data integrity mechanisms for inspection Check if the data has been changed in an unauthorized manner. It can also be used as a message authentication mechanism to ensure that the message comes from the entity that owns the key. The strength of the data integrity mechanism and the message authentication mechanism is determined by the following criteria. the length of the key (in bits) and the confidentiality, the hash function The length of the raw hash code (in bits), the strength of the hash function, the length of the MAC (in bits), and the specific mechanism. Note. The general framework for providing integrity services is specified in ISO /IEC 10181-6 [7].
