Transmission Security

What Does Transmission Security Mean?

Transmission security (TRANSEC) is the process of securing data transmissions from being infiltrated, exploited or intercepted by an individual, application or device. TRANSEC secures data as it travels over a communication medium. It is generally implemented in military and government organization networks and devices, such as radar and radio communication equipment.


Techopedia Explains Transmission Security

TRANSEC is part of communication security (COMSEC) and is implemented and managed through several techniques, such as burst encoding, spread spectrum and frequency hopping. Each transmission stream is secured through a transmission security key (TSK) and cryptographic algorithm. Both the TSK and algorithm enable the creation of a pseudorandom sequence on top of the transmitted data. The key goals and objectives of TRANSEC are:

  • To create a low probability of interception (LPI) for transmissions
  • To create a low probability of detection (LPD) for the measures TRANSEC takes
  • To ensure antijam, or resistence to jamming
