【国外标准】 Information technology - Security techniques - Key management - Part 4: Mechanisms based on weak secrets

Defines key establishment mechanisms based on weak secrets, i.e., secrets that can be readily memorized by a human, and hence, secrets that will be chosen from a relatively small set of possibilities. It specifies cryptographic techniques specifically designed to establish one or more secret keys based on a weak secret derived from a memorized password, while preventing offline brute-force attacks associated with the weak secret.
