PKI security in large-scale healthcare networks
During the past few years a lot of PKI (Public Key Infrastructures) infrastructures have been proposed for healthcare networks in order to ensure secure communication services and exchange of data among healthcare professionals. However, there is a plethora of challenges in these healthcare PKI infrastructures. Especially, there are a lot of challenges for PKI infrastructures deployed over large-scale healthcare networks. In this paper, we propose a PKI infrastructure to ensure security in a large-scale Internet-based healthcare network connecting a wide spectrum of healthcare units geographically distributed within a wide region. Furthermore, the proposed PKI infrastructure facilitates the trust issues that arise in a large-scale healthcare network including multi-domain PKI infrastructures
Calculating and Evaluating Trustworthiness of Certification Authority
In a public key infrastructure trust model, a trust is transferred along a set of certificates, issued by certificate authorities (CAs) considered as trustfully third parties, providing a trust chain among its entities. In order to deserve this trustworthiness, a CA should to apply the rigorous procedures for generating keys, checking the identities, and following reliable security practices. Any deficiency in these procedures may in?uence its trustworthiness. In this context, some authorities could be weaker than others. Then, relying parties (RPs) and certificate holders (CHs) need a mechanism to evaluate CA trustworthiness. In this paper, we provide them this mechanism to have information about its trustworthiness. In fact, we propose a trust level calculation algorithm that is based on three parameters which are the CA reputation, the quality of procedures described in the certi?cate policy and its security maturity level
Securely sharing dynamic medical information in e-health
This thesis has introduced an infrastructure to share dynamic medical data between mixed health care providers in a secure way, which could benefit the health care system as a whole. The study results of the universally data sharing into a varied patient information system prototypes
