PKI Security in Large-Scale Healthcare Networks

Experience with Pki in a Large-scale Distributed Environment

PKI shows some weaknesses when used in real deployment, such as problems with securing the private key, combination of PKI with other authentication systems, availability of revocation information, user-friendliness of PKI system and relationship with federation systems. In this paper we present solutions that were used during PKI deployment in a grid distributed environment.

Distributing security-mediated PKI

The security-mediated approach to PKI offers several advantages, such as instant revocation and compatibility with standard RSA tools. In this paper, we present a design and prototype that addresses its trust and scalability problems. We use trusted computing platforms linked with peer-to-peer networks to create a network of trustworthy mediators and improve availability. We use threshold crypt...

Security Challenges in Fog Computing in Healthcare

Background and Aim: The Fog Computing is a highly virtualized platform that provides storage, computing and networking services between the Cloud data centers and end devices. Fog computing fits the characteristics of real-time health monitoring systems. In such systems, a large amount of data is acquired from a multitude of bio and environmental sensors. On the other hand, its distribution and...

Decentralized Interaction Estimators in Large Scale Power Systems with Neural Networks.

Large Scale Network Security Visualization

Intrusion Detection Systems and other network security tools often provide only text-based output. Multiple systems are employed by network security analysts, which means that the analyst is required to focus on and pay attention to multiple screens, lists and textual output that these systems provide. Even correlation and fusion engines that combine the output of many intrusion detection senso...
