1. The art or science concerning the principles, means, and methods for rendering plain information unintelligible, and for restoring encrypted information to intelligible form. 2. The branch of cryptology that treats of the principles, means, and methods of designing and using cryptosystems. 3. The discipline which embodies principles, means, and the methods for the transformation of data in order to hide its information content, prevent its undetected modification and/or prevent its unauthorized use. Note: Cryptography determines the methods used in encipherment and decipherment. An attack on a cryptographic principle, means, or methods is cryptanalysis.

1. The basis for coordinated dissemination of time signals, counted from 0000 at midnight. 2. In celestial navigation applications, the time which gives the exact rotational orientation of the Earth obtained from UTC by applying increments determined by the U. S. Naval Observatory. 3. A measure of time that conforms, within a close approximation, to the mean diurnal rotation of the Earth and serves as the basis of civil timekeeping. Note: Universal Time (UT1) is determined from observations of the stars, radio sources, and also from ranging observations of the Moon and artificial Earth satellites. The scale determined directly from such observations is designated Universal Time Observed (UTO); it is slightly dependent on the place of observation. When UTO is corrected for the shift in longitude of the observing station caused by polar motion, the time scale UT1 is obtained. When an accuracy better than one second is not required, Universal Time can be used to mean Coordinated Universal Time (UTC. ) Synonym Zulu Time. 4. The official civil time of the United Kingdom. Formerly called Greenwich Mean Time.

1. The combination of a hierarchical security classification and a set of security categories that represents the sensitivity of an object or the security clearance of a subject. 2. The combination of hierarchical classification and a set of non- hierarchical categories that represent the sensitivity of information.

1. The communications facilities between adjacent nodes of a network. Synonym telecommunications link. 2. A portion of a circuit connected in tandem with, i. E. , in series with, other portions. 3. A radio path between two points, called a radio link. 4. In communications, a general term used to indicate the existence of communications facilities between two points. 5. A conceptual circuit, i. E. , logical circuit, between two users of a network, that enables the users to communicate, even when different physical paths are used. Note 1: In all cases, the type of link, such as data link, downlink, duplex link, fiber optic link, line-of-sight link, point-to-point link, radio link and satellite link, should be identified. Note 2: A link may be simplex, half-duplex, or duplex. 6. In a computer program, a part, such as a single instruction or address, that passes control and parameters between separate portions of the program. 7. In hypertext, a logical connection between discrete units of data, or a hypertext connection between Web pages. Synonyms (in this sense) hotlink, hyperlink.

1. The complete set of signals, usually electromagnetic or acoustic, received from a source such as an infrared object, a radio or radar transmitter, an aircraft, or a ship. Note: Signatures may consist of analog or digital signals, or both, and may be analyzed to indicate the nature of their source and assist in its recognition. 2. The attributes of an electromagnetic or acoustic wave that has been reflected from or transmitted through an object and contains information indicating the attributes of the object. Note: In this context, "objects" may include man-made objects or natural ones, the latter including both those that are well defined, e. G. , terrain, and those that are not, e. G. , weather phenomena. See also digital signature.

1. The concept of processing information with different classifications and categories that simultaneously permits access by users with different security clearances and denies access to users who lack authorization. 2. A system operating in this mode is one which stores and/or processes data at various classifications etc, but for which there are users not cleared for or who need to know about all the data and whose access is restricted appropriately. See also: Dedicated Security Mode, System High Security Mode, Compartmented Security Mode.

1. The degree to which a system, subsystem, or equipment is operable and in a committable state at the start of a mission, when the mission is called for at an unknown, i. E. , a random, time. Note 1: The conditions determining operability and committability must be specified. Note 2: Expressed mathematically, availability is 1 minus the unavailability. 2. The ratio of (a) the total time a functional unit is capable of being used during a given interval to (b) the length of the interval. Note 1: An example of availability is 100/168 if the unit is capable of being used for 100 hours in a week. Note 2: Typical availability objectives are specified in decimal fractions, such as 0. 9998. 3. Timely, reliable access to data and information services for authorized users. 4. The prevention of denial of service. 5. The property of being accessible and useable upon demand by an authorized entity. 6.
