Title

Passwords

Control

Passwords are used for identity authentication or authorization, and, in some cases, to derive keying material (see [SP800-132] ). Passwords may be distributed, but their protection during distribution shall be consistent with the protection required for their use. For example, if the password will be used to access cryptographic keys that are used to provide 128 bits of security strength when protecting data, then the password needs to be provided with at least 128 bits of protection as well. Note that poorly selected passwords may not themselves provide the required amount of protection for key access and are potentially the weak point of the process; i.e., it may be far easier to guess the password than to attempt to “break” the cryptographic protection used on the password. It is the responsibility of users and organizations to select passwords that provide the requisite amount of protection for the keys they protect.
