SC-40(04) Signal Parameter Identification

NIST SP 800-53 (controls) 5.2.0 against 5.2.0
All changes in this version
unchanged SC part of SC-40

Title

Signal Parameter Identification

Control

Implement cryptographic mechanisms to prevent the identification of [Assignment: wireless transmitters] by using the transmitter signal parameters.

Discussion

The implementation of cryptographic mechanisms to prevent the identification of wireless transmitters protects against the unique identification of wireless transmitters for the purposes of intelligence exploitation by ensuring that anti-fingerprinting alterations to signal parameters are not predictable by unauthorized individuals. It also provides anonymity when required. Radio fingerprinting techniques identify the unique signal parameters of transmitters to fingerprint such transmitters for purposes of tracking and mission or user identification.

Parameters

sc-40.04_odp: wireless transmitters
