Embodiment Construction

[0013] The object of the present invention is a trust management method in the distributed internet of things based on block chain, this method is made up of trust management model and trust evaluation two parts, content is as follows:

[0014] Design of Trust Management Model

[0015] ①Evaluation value

[0016] D(x i ,y m ) evaluation value is denoted as δ(x i ,y m ,x j ,y n ,l), refers to the IoT device D(x i ,y m ) received by other IoT devices D(x j ,y n ) given by the evaluation, defined as:

[0017]

[0018] where l represents D(x i ,y m ) The serial number currently receiving the evaluation, if the device number y is not given here m and y n , then the evaluation value represents H(x i ), which refers to the domain manager H(x j ) to domain manager H(x i )evaluation of.

[0019] ② trust value

[0020] D(x i ,y m ) is recorded as TC(x i ,y m ,k), according to the evaluation value δ(x i ,y m ,x j ,y n ,l) to iterate, defined as:

Abstract

The invention relates to the field of information security, and discloses a trust management method suitable for distributed internet of things. In order to solve the problems of malicious evaluationbetween Internet of Things devices and dependence on a trusted third party, the invention provides the trust management method suitable for distributed Internet of Things. The trust management methodis mainly composed of a trust management model and an evaluation method. Trust is quantified into expected credit and risk, the credibility degree of the Internet of Things is comprehensively considered, the credibility degree of one Internet of Things device is judged, suspicious malicious evaluation is recognized in the trust data storage process. A device can be operated with the reliable Internet of Things devices for cooperation, and the reliability of the Internet of Things devices is improved. Therefore, the success rate of cooperation between Internet of Things devices is improved. Moreover, storage and release of trust data are realized by means of the block chain, and effective sharing and security of the trust data are further realized.

Description

technical field [0001] The invention belongs to the field of information security and relates to the use of block chain technology. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain has the characteristics of distributed trust, openness and transparency, and information cannot be tampered with, and can realize data sharing and integrity protection. [0003] The research on trust management in the Internet of Things started earlier at home and abroad. In 2014, Lize et al. divided the trust of the Internet of Things into sensor layer, network layer and application layer, and used fuzzy theory to fuse the information of multiple layers to calculate a The object's global reputation. In 2013, Saied et al. tried to use multiple functions to evaluate the trust of different devices, and proposed a trust management syste...
