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.
