Information Flow Analysis in Role-based Security Systems 1

چکیده
This paper examines the application of information ow analysis to role-based protection systems. Starting with basic information ow axioms and a security policy, we propose a means of ensuring that a given role-based scheme is consistent with the speciied security policy. The proposed method uses graph theory and, in particular, treats this problem as an instance of subgraph isomorphism to determine the consistency of a role-based scheme with a given security policy.

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 کاملOn the design and security of a lattice-based threshold secret sharing scheme
In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...
