Method for evaluating trust of user action in trusted network

Abstract

The invention relates to a method for evaluating the trust of a user action in a trusted network. In the method, distributed computing technology, trusted computing technology, trust management technology are applied to the construction of a trust evaluation vector comprising a priority array serving as a storage structure and resource evaluates the trust according to the trust evaluation vectors provided by other users having transaction histories with a user so as to provide basis for trust decision. The trust evaluation vector consists of four parts which are transaction duration, transaction results, transaction value and trust value respectively, wherein the transaction duration ensures timeliness of the trust evaluation; the transaction results are accumulated to ensure that the trust can be successfully and quickly reduced; and the transaction value is defined to reflect different positions and functions of transactions with different values in the trust evaluation. By adopting the whole evaluation executing scheme, the timeliness of the trust is improved, the resource can conveniently realize reliable and independent trust decision, and a novel idea is provided for realizing the method for evaluating the user action in the trusted network and constructing trust models of the trusted network.

Description

technical field [0001] The invention relates to an implementation method for realizing user behavior trust evaluation in a trusted network, which mainly uses distributed computing technology, trusted computing technology and trust management technology to solve the problem of trust evaluation of user behavior in a trusted network, and belongs to distributed Computing, information security, and trusted computing cross-technical application fields. Background technique [0002] With the rapid development of network technology and applications, the Internet is increasingly complex and heterogeneous. Ensuring the reliability of the network has become an urgent need for the further development of the network. The initial concept of absolute liberalism in network applications and the anarchy of management are no longer suitable for the current actual network development, and a new order of trusted network behavior needs to be established. The computer network system has changed f...

Problems solved by technology

These trust models all provide the implementation scheme of user behavior trust evaluation, but since the focus of these research work is to propose a trust model, there is no special research on the trust requirements of trusted networks, so they are directly applied to users in trusted networks. There must be some problems in the measurement of behavioral trust
