<h:p>For the selection in this requirement, the ST author selects "TSF noise source" if a single noise source is used as input to the DRBG. The ST author selects "multiple TSF noise sources" if a seed is formed from a combination of two or more noise sources within the TOE boundary. If the TSF implements two or more separate DRBGs that are seeded in separate manners, this SFR should be iterated for each DRBG. If multiple distinct noise sources exist such that each DRBG only uses one of them, then each iteration would select "TSF noise source"; "multiple TSF noise sources" is only selected if a single DRBG uses multiple noise sources for its seed. The ST author selects "TSF interface for seeding" if noise source data is generated outside the TOE boundary.<h:p/>If "TSF noise source" is selected, FCS_RBG.3 must be claimed.<h:p/>If "multiple TSF noise sources" is selected, FCS_RBG.4 and FCS_RBG.5 must be claimed.<h:p/>If "TSF interface for seeding" is selected, FCS_RBG.2 must be claimed.</h:p>
