Method for demonstrating knowledge of a secret, in which both entities share a common authentication information [10181-2].

Cryptography in which the same key is used for encryption and decryption. [2382-pt.8]

A channel in which the send and receive circuits have the same data signaling rate.

A balanced transmission line, in a multipair cable, having equal conductor resistances per unit length, equal impedances from each conductor to earth, and equal impedances to other lines.

The attribute describing the relationship of information flow between two (or more) access points or reference points involved in a communication. Symmetry characterizes the structure associated with a telecommunication service or a connection. Values associated with this attribute are unidirectional, bidirectional symmetric, and bidirectional asymmetric. [After T1.603-1990] [After T1.604-1990]

Acronym for synchronous idle character.

Synonym synchronization pulse.

1. The state of being synchronous.
2. For repetitive events with the same, multiple, or submultiple repetition rates, a relationship among the events such that a significant instant of one event bears a fixed time relationship to a corresponding instant in another event.
Note: Synchronism is maintained when there is a fixed, i.e., constant, phase relationship among the group of… (Read More →)
