Research On Risk Assessment Model And Application Of Heterogeneous Identity Alliance Architecture

With the rapid development of networks and application technologies,there are diversified,non-interoperable,credible assessments of cross-domain identities,lack of risk assessments,identity information forgery,abuse,and polymorphic identity in identity management in the network environment.Information is difficult to manage in a unified manner,and building a multi-domain and multi-modal identity that manages network entities has become a technical problem.Especially to supervise the identity in heterogeneous environment.The identity supervision in heterogeneous environment has diversified identity platforms and is not interoperable;cross-domain identity credibility assessment is missing;identity information is forged;identity information is misused;network identity is difficult to manage in a polymorphic network;network behavior is difficult to monitor,etc.problem.There are still risks of identity fraud,abuse,system data being tampered with,and embezzlement in the heterogeneous identity alliance,but the research on the risk assessment of the heterogeneous identity alliance is currently less,so this paper mainly focuses on the architecture and algorithm of the heterogeneous identity alliance were studied.This paper takes the heterogeneous identity alliance's identity supervision as the background and takes the heterogeneous identity alliance's risk assessment model as the research goal.Starting from the risk assessment model's architecture and algorithm,it introduces the blockchain technology and AHP fuzzy AHP theory.Aiming at the lack of research on the architecture of heterogeneous identity alliance risk assessment and the existing risk assessment architecture,the data is easy to be tampered with and difficult to audit.Using blockchain technology,a risk assessment architecture based on blockchain is proposed.Aiming at the problem of the lack of heterogeneous identity alliance risk assessment algorithm,the theory of AHP fuzzy analytic hierarchy process is used to study and propose a risk assessment algorithm based on AHP fuzzy analytic hierarchy process.Finally,through simulation application,a risk evaluation system based on Ethereum blockchain technology and AHP hierarchical fuzzy evaluation method is realized,which achieves the effect of guaranteeing the authenticity and effectiveness of the evaluation data.The main research results of this article are as follows:(1)Researched and proposed a risk assessment system based on the blockchain architecture.The system takes advantage of the de-neutralization of the blockchain to ensure the authenticity,confidentiality,and non-tampering of the data,and can audit the risk assessment(2)Research and put forward a risk assessment method based on AHP fuzzy analytic hierarchy process.This method uses AHP analytic hierarchy process to analyze the risk assessment problem of heterogeneous identity alliance,combined with fuzzy comprehensive evaluation reduces the subjectivity of AHP analytic hierarchy process and the redundancy of risk matrix I can finally get the quantitative results of the risk assessment under the heterogeneous identity alliance.(3)In order to test the rationality,feasibility,and effectiveness of the heterogeneous identity alliance risk assessment system and the AHP fuzzy analytic assessment method based on the previous research,a risk assessment system based on the Ethereum blockchain was designed.To ensure the authenticity and effectiveness of the evaluation data.
