Method for generating cross-domain access control strategy by rising from credit assessment to trust management

Abstract

The invention relates to a method for generating a cross-domain access control strategy by rising from credit assessment to trust management. According to the method, a credit assessment model is established to realize a corresponding credit assessment subsystem; uncertainty assessment is carried out on a credit degree of an evaluated entity according to evaluation information given by an interaction entity; association relations between an attribute of an assessment entity, an attribute of an assessed entity, a resource attribute, a behavior attribute, an environment attribute and an entity credit degree are extracted; and then an access control strategy based on attributes is generated and description is carried out by an extensible access control mark language; at last, the generated access control strategy is converted into a strategy of a concrete trust management system. According to the invention, authorization strategy is generated dynamically according to behavior and environment attributes of an entity; and the method has good self adaptability and can be applied to cross-domain environments like cloud calculating having a lot of unfamilar entities.

AI Technical Summary

Benefits of technology

This new method uses an Access Control Strategy Language (X ACML) that simplifies how it can be transformed from different ways for integration purposes within older systems without compromising its effectiveness or functionality.

Problems solved by technology

Technological Problem addressed in this patents relating to improving flexibility in accessing remote devices over internet protocol networks has been challenging due to lack of confidence in validated identity verification measures like creditworthiness ratings and trust governance. Companionship refers to combining reliability and ease of access into multiple levels of trust. However, existing methods either require separate validation sources or rely heavily on weaknesses derived from past experiences.
