1. In cryptology and cryptosystems, that characteristic allowing one entity to assume that a second entity will behave exactly as the first entity expects.
Note: Trust may apply only for some specific function. The critical role of trust in the authentication framework is to describe the relationship between an authenticating entity and a certification authority; an authenticating entity must be… (Read More →)

1. [An] information system (IS) employing sufficient hardware and software assurance measures to allow simultaneous processing of a range of classified or sensitive information. [INFOSEC-99]
2. A data processing system that provides sufficient computer security to allow for concurrent access to data by users with different access rights and to data with different security classification and security categories. [2382-pt.8]

1. [The] totality of protection mechanisms within a computer system , including hardware , firmware , and software , the combination of which is responsible for enforcing a security policy. [INFOSEC-99]
Note: The ability of a trusted computing base to enforce correctly a unified security policy depends on the correctness of the mechanisms within the trusted computing base, the protection… (Read More →)

[A] method for distributing trusted computing base (TCB) hardware, software, and firmware components that protects the TCB from modification during distribution. [INFOSEC-99]

A function whose correct operation is relied upon for the security policy to be upheld [CESG].
Note: The term is normally used after the establishment of the evaluation baseline, to relate to representations produced subsequent to the system requirements (e. g. functional specification and design specification). See also: Security Function.

That which is perceived to be correct with respect to some criteria, e.g., as established by a security policy [7498-2].

[The] identification method used in information system (IS) networks whereby the sending host can verify an authorized user on its system is attempting a connection to another host. The sending host transmits the required user authentication information to the receiving host. [INFOSEC-99]

The subnetwork formed by an association of interconnected Trusted Network Interface Units and one or more Access control Systems [CESG]. See also Trusted Network Interface Unit below.

TNET (see Trusted Network above) will be realized by the development of a number of components including the TNIU and ACS. The TNIU is located between the end system and the network that provides separation, integrity, access control and authentication services by means of encryption across the network and supports the operation of the TNIUs by providing them with the… (Read More →)
