Security of Mobile Agent Platforms using RBAC based on Dynamic Role Assignment
Hind IDRISSI,Arnaud REVEL,El Mamoun SOUIDI 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.4
Mobile agent technology is a new trend in the network computing. It succeeds to capture researchers' and industry's interests long time ago, due to its innovative capabilities and attractive applications. Mobile agents are self-contained data and software modules, able to autonomously move from one host to another across the network, in order to perform their tasks and eventually return to their initiators. Despite their several qualities that make them suitable for various disciplines, where autonomy, dynamism and flexibility are strongly recommended, mobile agents still suffer from some limitations mainly related to the security issues raised by mobility. In this paper, we propose a novel approach to address the security problems evoked by platforms hosting mobile agents, particularly those caused by unauthorized access attacks. Our approach introduces a robust security policy for a Hospital, where a flexible role-based access control model (RBAC) is used and simulated as a set of cooperative agents. We implant a privilege management infrastructure (PMI) charged with issuing attribute certificates based on elliptic curve cryptography, in order to provide this model with a dynamic role assignment. Finally, practical experiments are conducted to evaluate our approach and prove its effectiveness, reliability and security.

Mobile Agent Security Using ID-Based Agreement Protocol and Binary Serialization
Hind Idrissi,El Mamoun Souidi,Arnaud Revel 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.5
Recent days, the systems based on mobile agents have attracted the attention of many researchers in different areas, because of the autonomic and pro-active aspects of the agent, as well as its adaptive and dynamic behaviors in solving complex problems. However, the mobility of these entities needs to be secured against multiple vulnerabilities that present a real obstacle to its wide expansion. When the mobile agent is migrating from one node to another over the network, it is difficult to guarantee that it will be executed safely and correctly on the hosting platform, neither that it will not encounter in its way malicious entities that try to harm it. In this paper, we try to address these security issues by introducing an approach based on cryptographic mechanisms. This approach involves an Identity-Based Key Agreement Protocol to get a session key and ensure authentication, an Advanced Standard Encryption (AES) for the confidentiality of data exchanged, as well as a Binary Serialization to get an easy and persistent portability of the agent across the network.
