1. In cryptosystems, a functional unit that can simultaneously process data of two or more security levels without risk of compromising computer security. [2382-pt.8] 2. A device that is used in a manner that permits it to simultaneously process data of two or more security levels without risk of compromise. To accomplish this sensitivity labels are normally stored on the same physical medium and in the same form (i.e., machine-readable or human-readable) as the data being processed [TCSEC].
