ACP 122(F)
805. Appropriate and approved CRYPTOSEC measures shall be used to safeguard
confidentiality, integrity, availability, and/or accountability of all classified and extremely
sensitive information stored or transmitted by electronic means. As well, where justified by a
TRA, electronic information of a low-sensitive or particularly sensitive nature shall be protected
by approved cryptographic methods.
806. CRYPTOSEC relies on two basic building blocks:
a. Crypto Devices. Used to provide data confidentiality and integrity while being
transmitted through hostile environments, and managed in accordance with current
National and Allied publications, and
b. Keying Material. Keying material for Crypto Devices, provided from National or
Allied sources and handled in accordance with current National and Allied
publications.
807. CRYPTOSEC activities in an Allied and Coalition context will be handled in line with
existing national procedures.
TRANSMISSION SECURITY (TRANSEC)
808. TRANSEC is that component of information security that results from the application of
measures designed to protect transmissions from interception and exploitation by means other
than crypto analysis.
809. Traffic flow analysis is a form of threat against communications from which
intelligence can be gained, despite the use of encryption on the content of the traffic. It should
be considered when designing and fielding a CIS that uses an uncontrolled transmission medium
(e.g., free space or public carrier).
TRANSEC SCOPE
810. Telecommunication in this sense is defined as:
a. Communication by wire, radio, optical, or other electromagnetic means; and
b. Any transmission, emission or reception of signs, signals, writing, images and
sounds or intelligence of any nature by wire, radio, optical, or other
electromagnetic system.
TRANSEC MEASURES
811. TRANSEC activities in an Allied and Coalition context will be handled in line with
existing national procedures.
