Title

RBG Seeds

Control

A Random Bit Generator (RBG) is a device or algorithm that outputs a sequence of bits that is unpredictable; RBGs are often called Random Number Generators. Approved RBGs are specified in [SP800-90] . RBGs depend on the introduction of truly random bits called seeds, which are used to initialize an RBG and that must be kept secret. An initialized RBG is often used to generate keys and other values requiring unpredictability. The seeds themselves shall not be used for any purpose other than RBG input. Seeds shall only be transmitted using secure channels that protect the confidentiality and integrity of the seeds, as well as providing replay protection 41 and mutual authentication 42 .
