Frequent communication to specific stations from a central station – can highlight the chain of command.A lack of communication – can indicate a lack of activity, or completion of a finalized plan.Rapid, short communications – can denote negotiations.Frequent communications – can denote planning.

In a military context, traffic analysis is a basic part of signals intelligence, and can be a source of information about the intentions and actions of the target. It is shown, although timing noise is added to the packets, there are active traffic analysis methods robust against such a noise. In active traffic-analysis method, the attacker alters the timings of the packets of a flow according to a specific pattern and looks for that pattern on the other side of the network therefore, the attacker can link the flows in one side to the other side of the network and break the anonymity of it.In passive traffic-analysis method, the attacker extracts features from the traffic of a specific flow on one side of the network and looks for those features on the other side of the network.There are two methods of traffic-analysis attack, passive and active. Traffic analysis method can be used to break the anonymity of anonymous networks, e.g., TORs. Traffic analysis has historically been a vital technique in cryptanalysis, especially when the attempted crack depends on successfully seeding a known-plaintext attack, which often requires an inspired guess based on how specific the operational context might likely influence what an adversary communicates, which may be sufficient to establish a short crib.īreaking the anonymity of networks Advanced traffic analysis techniques which may include various forms of social network analysis.

Traffic analysis tasks may be supported by dedicated computer software programs. Traffic analysis can be performed in the context of military intelligence, counter-intelligence, or pattern-of-life analysis, and is also a concern in computer security. In general, the greater the number of messages observed, the greater information be inferred.

It can be performed even when the messages are encrypted. Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in communication. This article is about analysis of traffic in a radio or computer network.
