The study of history aging model in network trust evaluation

Liu Xiaojun

Abstract

The history aging model, followed trust natural quality of attenuation and dynamic, utilized time quantity to quantify the important degree of historical reference value. Combined with trust assessment and its history occurred moments, it gave the objective description on history trust evaluation by the methods of threshold space and induce ordered weighted averaging (IOWA) operators. History aging model transparentized trust evaluation content, and calculated the value of dynamic degree to network objects. It also improved the trust assessment accuracy of network security applications. Through historical aging model’s design rules, method, and experimental analysis, it pointed its limitation, flaws and future research direction.
