Scope

GB/T 15852.3-2019 is the English-translated version of 信息技术安全技术消息鉴别码第3部分：采用泛杂凑函数的机制.

GB/T 15852.3-2019 is the Chinese standard "Information technology -- Security techniques -- Message authentication codes (MACs) -- Part 3: Mechanisms using a universal hash-function".

Its scope clause reads: 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]. Its clauses include terms and definitions.

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.
