Distributed Data Access Control for Lean Product Information Sharing in Collaborative Design

Abstract

Efficient, effective, and trustworthy collaboration in design is vital to maintain organizational competence. Conventional access control methods are too coarse in inter-organizational lean and secure data exchange. In this paper, a Scheduled Role-Based Distributed Data Access Control Model is described to support data security management in a distributed environment. The model allows for fine-grained data access control at both the server and client sides, thus securing different levels of design information dissemination for intellectual property protection purposes. Common interface for heterogeneous data is built based on XML.

The structural design and technical investigations of data resources sharing system in the field of aero engine

“…Kao et al (2004) discussed various emerging technologies that enable a true B2B virtual collaboration of an aircraft engine combustor design between GE aircraft engines, a jet engine manufacturer and Parker Hannifin, a gas turbine fuel nozzle supplier. Wang et al (2004) described a scheduled role-based distributed data access control model to support data security management in a distributed environment. This model combines RBAC and cryptography models for fine-grained data access control such that lean and secure data exchange and sharing are supported.…”
