Authorization and Attribute Certificates for Widely Distributed Access Control
We describe a system whose purpose is to explore the use of certificates for the distributed management of access rights for resources that have multiple, independent, and geographically dispersed stakeholders. The stakeholders assert their use-conditions in authorization certificates and designate those trusted to attest to the corresponding attributes. These use-conditions implicitly define a...
متن کاملPKI based Access Control with Attribute Certificates for Data held on Smartcards
Common smartcard systems are not capable of providing effective Data Access Control in distributed IT-infrastructures with high configuration dynamics. The crucial points of that approach are resource consumption and inflexibility. The storage capacity of actual smartcards is clearly insufficient to store large certificate databases required by distributed services and applications. The exchang...
متن کاملAttribute-based Access Control for Cloud-based Electronic Health Record (EHR) Systems
Electronic health record (EHR) system facilitates integrating patients' medical information and improves service productivity. However, user access to patient data in a privacy-preserving manner is still challenging problem. Many studies concerned with security and privacy in EHR systems. Rezaeibagha and Mu [1] have proposed a hybrid architecture for privacy-preserving accessing patient records...
متن کاملA combination of semantic and attribute-based access control model for virtual organizations
A Virtual Organization (VO) consists of some real organizations with common interests, which aims to provide inter organizational associations to reach some common goals by sharing their resources with each other. Providing security mechanisms, and especially a suitable access control mechanism, which enforces the defined security policy is a necessary requirement in VOs. Since VO is a complex ...
متن کاملAnonymous attribute certificates based on traceable signatures
Purpose – To provide a cryptographic protocol for anonymously accessing services offered on the web. Such anonymous accesses can be disclosed or traced under certain conditions. Design/methodology/approach – The “traceable signature” scheme was used in conjunction with the “privilege management infrastructure”. Findings – The cryptographic primitive provides a suitable tool for anonymous and un...
