Method, device and communication system for evaluating network trust degree

Abstract

The invention discloses a method for evaluating the network trust level, which comprises the steps as follows: a trust request for a network entity to be tested, which is sent by a network accession user, is received; the trust information related to the network entity to be tested is extracted, and the trust information includes a historic direct trust level, a recommendation trust level, a current direct trust level, a recommendation main credibility and a trust timestamp; and the trust level of the network entity to be tested can be worked out according to the related trust information. The embodiment of the invention also discloses a device which can evaluate the network trust level and a communication system thereof. The technical proposal of the invention can comprehensively and effectively evaluate the trust level of the network to be tested, and can perfectly deal with strategic attacks executed by malicious networks and assailment or cooperative cheat executed by the malicious recommending users.

Description

technical field [0001] The present invention relates to the field of network security management, more specifically, to a method, device and communication system for evaluating network trustworthiness. Background technique [0002] The heterogeneous network is composed of a variety of networks using different access technologies. It is committed to providing users with a convenient network connection on a common open network platform to meet the business needs of users to the greatest extent. The open network architecture brings new security risks while integrating the advantages of respective networks, and adds many uncertainties to the security of heterogeneous networks. Honest network entities may also not implement the promised service quality, thereby affecting user productivity. Therefore, how to clarify the trust relationship between heterogeneous networks and users, and effectively control mobile users' access to network entities has become an important problem to b...
