One of several technologies used to separate multiple conversation transmissions over a finite frequency allocation of throughtheair bandwidth. TDMA is used to allocate a discrete amount of frequency bandwidth to each user in order to permit many simultaneous conversations. However, each caller is assigned a specific time slot for transmission.

A technique for transmitting a number of separate data, voice, and video signals simultaneously over one communications medium by interleaving a piece of each signal one after another.

Method of representing a signal where the vertical deflection is the signals amplitude, and the horizontal deflection is the time variable.

A timing vulnerability that occurs when a program checks access permissions too far in advance of a resource request.

A password that is valid only at a certain time of day or during a specified timeframe.

The practice of tagging each record with some moment in time, usually when the record was created or when the record was passed from one environment to another.

Transport Layer Security protocol.

A password-generating device that subjects must carry with them. Token devices are a form of a “something you have” (Type 2) authentication factor.

A network access method that uses a distinctive character sequence as a symbol (token), which is passed from node to node, indicating when to begin transmission. Any node can remove the token, begin transmission, and replace the token when it is finished.

The highest level of government/military classification. Unauthorized disclosure of top-secret data will cause exceptionally grave damage to national security.
