标准摘要
[中文适用范围]: ISO/IEC 10118 的这一部分指定了使用 n 位分组密码算法的散列函数。 因此,它们适用于已经实现这种算法的环境。 指定了四个散列函数。 第一个提供长度小于或等于 n 的哈希码,其中 n 是所使用的基础分组密码算法的分组长度。 第二个提供长度小于或等于 2n 的哈希码;第三个提供长度等于 2n 的哈希码;第四个提供长度为 3n 的哈希码。 ISO/IEC 10118 本部分中指定的所有四个散列函数均符合 ISO/IEC 10118-1 中指定的通用模型。 [外文原描述]: ISO/IEC 10118-2:2010 specifies hash-functions which make use of an n-bit block cipher algorithm. They are therefore suitable for an environment in which such an algorithm is already implemented. Block ciphers are specified in ISO/IEC 18033-3. Four hash-functions are specified. The first provides hash-codes of length less than or equal to n, where n is the block-length of the algorithm used. The second provides hash-codes of length less than or equal to 2n; the third provides hash-codes of length equal to 2n; and the fourth provides hash-codes of length 3n. All four of the hash-functions specified in ISO/IEC 10118-2:2010 conform to the general model specified in ISO/IEC 10118-1.
