Presentation of an efficient and secure architecture for e-health services

Abstract

Nowadays a great number of activities are performed via internet. With increment in such activities, two groups of services are required for providing a secure platform: 1- Access control services, 2- communication security services. In this article we propose a secure and efficient system for establishment of secure communication in e-health. This architecture focuses on five security indicators of authorization, authentication, integrity, non-repudiation and confidentiality. This architecture uses an efficient encryption scheme, which is a combination of the public key and the symmetric key encryption systems, all of which are combined with a log strategy In this article we have used a new role-based control model to provide the security requirement of authorization for user's access to data. Data sensitivity is measured based on the labels given to the roles; and then these data are encrypted with proper cryptography algorithms. In a comparison of these architectures, you will see that this architecture enjoys an efficient mechanism, which is very suitable and practical for communication and interchange of data. © 2011 Springer-Verlag Berlin Heidelberg.
