Farmland Environment Based On User Trust Value And Attribute Research On Data Access Control System

In the field of agricultural information,users want to understand farmland environmental data(temperature,humidity,light intensity),usually the network is connected to the access control platform of farmland management,and users can access it regardless of where and when they are.However,in the face of multi-user access,the user's identity is indeed different.Although the network has brought convenience,the user is virtual in the network,and it is not certain that it is the person.If there is a violation or malicious operation,determine the user's behavior Whether you are trusted is particularly important.In the current open network,traditional access control cannot solve the impact of excessive visits and visit information interaction.In response to the above problems,this paper designs an access control system based on user trust values and attributes to carry out research on security control of farmland environmental data,which is of great practical significance.This article is the first to study whether the user's behavior is trusted,and proposes a user trust value evaluation model based on behavior calculation.The trust value evaluation system of user behavior is constructed,the maximum number of user violation behaviors is set according to the requirements,the violation behavior of users is recorded,and the trust behavior of users accessing the system is evaluated by dynamically calculating the user trust value.On this basis,to further study the problem of excessive visits and visit information interaction,a research on farmland environment data access control system based on user trust value and attributes is proposed.The method is to construct attribute-related rule definitions to form an attribute-based farmland environment data access control model,combined with the user trust value evaluation model based on behavior calculation,design the structure of the access control model based on user trust value and attributes.In order to solve the problem of farmland environmental data security access control,a farmland environmental data system based on user trust value and attribute access control model is designed.The system analysis,development environment,database,and system functions are designed in sequence.Finally,the system is designed according to the above research results,and the farmland environment function based on the user's trust value and attributes in the system and the user's trust value evaluation based on behavior calculation are implemented and tested.The overall improvement enables the system to have dynamic login access and dynamic calculation of user trust values,and the overall system dynamics and reliability are improved.Dynamic adjustments can be made in the later operation and maintenance to make the system expandable.
