Transmission security (TRANSEC) is the component of communications security that results from the application of measures designed to protect transmissions from interception and exploitation by means other than cryptanalysis. Goals of transmission security include:
The field includes cryptographic security, transmission security, emissions security and physical security of COMSEC equipment and associated keying material. COMSEC is used to protect both classified and unclassified traffic on military communications networks, including voice, video, and data. It is used for both analog and digital ...

A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent a simple form of replay attack, where an eavesdropper records the transmission and replays it at a later time to cause the receiver to 'unlock'. Such systems are typical in garage door openers and keyless car entry systems.
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
OTAR technology created by NSA inventor, innovator, and author, Mahlon Doyle [7] was operationally introduced to the US Department of Defense in 1988. Lieutenant Commander David Winters, an American naval officer in London and code master during the final years of the Cold War, [8] was first to recognize the necessity and security potential of OTAR.
The OST operates a nationwide communications system located in Albuquerque, New Mexico.
