Observación del tráfico de datos (presencia,
ausencia, dirección, volumen y frecuencia) en un canal de transmisión para
inferir información (ISO-7498-2). Cuando la dificultad de descifrar los datos
transmitidos por un canal es grande, este tipo de ataque puede proporcionar
interesantes conjeturas sobre los mismos. [Ribagorda:1997]

de flujos de tráfico (presencia, ausencia, cantidad, sentido y frecuencia). [ISO-7498-2:1989]
(en) traffic analysis
Gaining knowledge of
information by inference from observable characteristics of a data flow, even
if the information is not directly available (e.g., when the data is
encrypted). These characteristics include the identities and locations of the
source(s) and destination(s) of the flow, and the flow's presence, amount,
frequency, and duration of occurrence. [CNSSI_4009:2010]
1. (I) Gaining knowledge of
information by inference from observable characteristics of a data flow, even
if the information is not directly available (e.g., when the data is
encrypted).
These characteristics
include the identities and locations of the source(s) and destination(s) of the
flow, and the flow's presence, amount, frequency, and duration of occurrence.
The object of the analysis might be information in SDUs, information in the
PCI, or both. (See: inference, traffic-flow confidentiality, wiretapping.
Compare: signal analysis.)
