See binary-coded decimal notation.

Synonym binary-coded decimal notation.

1. In computer, communications, and automatic data processing systems, assigning a value or referent to an identifier.
Note: Examples of binding include assigning a value to a parameter, assigning an absolute address to a virtual or relative address, and assigning a device identifier to a symbolic address or label.
2. [In security, the] process of associating a specific communications terminal… (Read More →)

An aspect of the assessment of the effectiveness of a Target of Evaluation, namely the ability of its security enforcing functions and mechanisms to work together in a way which is mutually supportive and provides an integrated and effective whole [ITSEC].

Any specific and uniquely identifiable physical human characteristic, e.g., of the retina, iris, acoustic spectrum of the voice (i.e., voiceprint), fingerprint(s), handwriting, pattern of finger lengths, etc. , that may be used to validate the identity of an individual.
Note: Biometrics provide a highly secure means of identification, for purposes of security involving, e.g., Internet communications and cryptosystems.

[In INFOSEC] automated methods of authenticating or verifying an individual based upon a physical or behavioral characteristic. [INFOSEC-99]

Synonym phase-shift keying.

1. A signal that may assume either of two polarities, neither of which is zero.
Note 1: A bipolar signal may have a two-state non-return-to-zero (NRZ) or a three-state return-to-zero (RZ) binary coding scheme.
Note 2: A bipolar signal is usually symmetrical with respect to zero amplitude, i.e., the absolute values of the positive and negative signal states are nominally… (Read More →)

In a bipolar alternate mark inversion (AMI) signal, a "one" condition (mark, pulse) having the same polarity as its predecessor. [After T1.408-1990]

In a transparent material, anisotropism of the refractive index, which varies as a function of polarization as well as orientation with respect to the incident ray.
Note 1: The term "birefringence" means, literally, "double refraction. "
Note 2: All crystals except those of cubic lattice structure exhibit some degree of anisotropy with regard to their physical properties, including refractive index.… (Read More →)
