We describe security for a virtual heterogeneous machine (VHM). Our security architecture is based upon separation of services into four distinct domains. It is designed to take advantage of operating system support for domains, where available. We have chosen to use emerging public key technology as an interim solution to provide domain separation. A prototype demonstration of our architecture...

High quality of security is increasingly critical for applications running on heterogeneous distributed systems. However, existing scheduling algorithms for heterogeneous distributed systems disregard security requirements of applications. To address this issue, in this paper, we introduce security heterogeneity concept for our scheduling model in the context of distributed systems. Based on th...

Machine to machine (M2M) communication, which is also known as machine type communication (MTC), is one of the most fascinating parts of mobile communication technology and also an important practical application of the Internet of Things. The main objective of this type of communication, is handling massive heterogeneous devices with low network overheads and high security guarantees. Hence, v...

With the emergence of the Internet, collaborative computing has become more feasible than ever. Organizations can share valuable information among each other. However, certain users should only access certain portions of source data. The CHAOS (Configurable Heterogeneous Active Object System) project addresses security issues that arise when information is shared among collaborating enterprises...

Companies are aware of Big Data importance as data are essential to conduct their daily activities, but new problems arise with new technologies, as it is the case of Big Data; these problems are related not only to the 3Vs of Big Data, but also to privacy and security. Security is crucial in Big Data systems, but unfortunately, security problems occur due to the fact that Big Data was not init...

In this paper, we describe: (i) how agents can protect information from other agents and (ii) how servers that support agent cooperation can help in this process. We show that agents' data security policies can be encoded through three structures called metaknowledge, history and agent security tables. We develop a framework that allows arbitrary metalanguages and history maintenance policies t...
