DISTRIBUTED ASSURED NETWORK SYSTEM (DANS)

摘要

A computerized method for a distributed assured network system includes a plurality distributed monitoring nodes for sequential feeding the content of respective information sources to a detection agent. The detection agent uses an SPRT-based distributed sequential misbehavior detection scheme to process each MN observation with the probability of a false alarm PFA and probability of a miss detection PMD until a reliable decision can be made that either there is no malicious or faulty behavior detected, or that malicious or faulty behavior is detected. A cognitive reputation agent is provided within a DBG framework processes the output or detection metric from the detection agent relative to past behavior of the information sources to provide a reputation metric to a trust indication that provides an output representing the trustworthiness of information sources.
