ABSTRACT:
A system for passively analyzing an aggregation of communication signals simultaneously passing through a network link performs spectral analysis on a trace of communication traffic through the network link. The spectral analysis identifies period components of the trace corresponding to different communication signals. A system for deterring the passive analysis of signals aggregates communication traffic through a network link, such that a plurality of signals simultaneously pass through the network link. The plurality of signals is regulated such that the data packets corresponding to the plurality of signals leave the network link at a common rate. A memory temporarily stores the data packets as they enter the network link, and a timer maintains a fixed time interval for releasing the data packets from the memory.
