A sequence of Files losses in the Organization network, we are interested in determining whether the losses are caused by link errors only, or by the collective effect of link errors and malicious drop. Link error and malicious packet reducing are two sources for packet losses in multi-hop wireless ad hoc network. We are chiefly nervous in the insider-attack case, whereby hateful nodes that are fraction of the way exploit their knowledge of the communication context to selectively drop a miniature quantity of packets dangerous to the network presentation. Because the File dropping velocity in this case is equivalent to the channel error rate, “conventional algorithms” that are based on detecting the File loss rate cannot realize reasonable detection accuracy. To recover the detection accuracy, we suggest extending the correlations between lost Files. Furthermore, to assurance directly computation of these correlations, we expand a “homomorphic linear authenticator (HLA)” based public auditing structural design that allows the detector to substantiate the truthfulness of the files loss in sequence reported by nodes. This construction is privacy preserving, collusion evidence, and incurs low communication and storage expenses. To reduce the calculation glide of the baseline system, a “packet-block-based mechanism” is also proposed, which allows one to trade detection accuracy for inferior computation complexity
