Compromising emanations (codename)
- this page is a stub
TEMPEST is an NSA specification and a
NATO certification, referring to spying on information systems through
leaking emanations. This includes the emission of unintentional
intelligence-bearing signals, such as Radio Frequency (RF) signals, light
and acoustic vibrations [1]. If such signals are intercepted and analysed by
an adversary (side-channel attack),
they might disclose sensitive information. In cryptography,
this might lead to reconstruction of (part of) the plaintext.
In practice, TEMPEST covers methods to spy upon others, as well as methods to
shield equipment against such spying by others. The latter is also known as
Emission Security (EMSEC), which is a subset of Communications Security
(COMSEC). Protecting equipment against TEMPEST-based spying is done by means of
distance, shielding, filtering and masking.
Equipment to check a device for unwanted emanations, is part of
Technical Surveillance and Counter-Measures (TSCM).
