Two security domains that want to exchange information securely may need to agree on translations of mandatory access control (MAC) labels of their information, if their MAC labels have a different syntax or semantics. It is desirable that these translations do not introduce any confidentiality violations. We present a property, the security level translation property (SLTP), which must hold if the security level translation functions satisfy MAC confidentiality. This property is in some sense the best possible non-disclosure test of the level translations in the absence of a “common domain” that gives the real relationships among the levels of the two domains
