(also transmission security)
The process of making sure data transmissions can’t be infiltrated or intercepted by a person, application, or device. All traffic engineering data and management and control data in a TRANSEC-compliant network must be encrypted and hidden from an attacker. TRANSEC protects data as it moves through a communication channel. It is usually used in devices and networks utilized by the military and government. Spread spectrum, burst encoding, and frequency hopping are some of the methods used to create and maintain TRANSEC, which is a subset of COMSEC. A cryptographic algorithm and a unique transmission security key (TSK) are used to protect each individual data stream during transmission. The TSK and algorithm together make it possible to superimpose a random sequence on the data being sent.
Objectives of TRANSEC
Creating a low probability of interception for transmissions.
Creating a low probability of detection for the measures TRANSEC takes.
For jam resistance.
