dc:description | That part of eavesdropping concerned with the analysis of which parties are communicating and the volumes and timings of those communications, rather than the contents of the messages themselves. Some encryption systems do not protect users against traffic analysis, even though all the content my be encrypted. (ISD)
Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in communication. It can be performed even when the messages are encrypted and cannot be decrypted. In general, the greater the number of messages observed, or even intercepted and stored, the more that can be inferred from the traffic. (Wikipedia) |
