Network security is in a daily evolving domain. Every day, new attacks, virus or intrusion techniques are released. Hence, network devices, enterprise servers or personal computers are potential targets of these attacks. Current security solutions like firewalls, intrusion detection systems (IDS) and virtual private networks (VPN) are centralized solutions which rely mostly on the analyze of inbound network connections. This approach notably forgets the effects of a rogue station, whose communications cannot be easily controlled unless the administrators establish a global authentication policy using methods like 802.1x to control all network communications among each device. To the best of our knowledge, a distributed and easily manageable solution for the global security of an enterprise network does not exist. In this paper, we present a new approach to deploy a distributed security solution where communication between each device can be control in a collaborative manner. Indeed, each device has its own security rules, who can be shared and improved through exchanges with others devices. With this new approach, called grid of security, a community of devices ensures that a device is trustworthy and that communications between devices progress in respect of the control of the system policies. To support this approach, we present a new communication model that helps structuring the distribution of security services among the devices. Like this, we can secure both ad-hoc, local-area or enterprise networks in a decentralized manner, preventing the risk of a security breach in the case of a failure.

“…To accomplish the dispatching task, RD handles the so called neighbours view, establishing network routes to other nodes. Depending of the number of POs, this view may be limited to a reduced set of network addresses to be contacted individually (as in the case of Figure 3), or deployed via complex data structures and algorithms like those used in Super-Peer networks such as DHT [ 30] or random walk [ 31].…”

Abstract. Due to their complexity, the exploitation of Grid environments is not a trivial activity for many users, and a key factor is to enable a simplified and transparent orchestration of resources and jobs. Particularly critical is the deployment of matching procedures capable to effectively meet user's requirements with resources offer. We introduce GREEN a management tool primarily devoted to the matchmaking process, based on a performance characterization of both resources and job requirements. Leveraging on a two-level benchmarking methodology, GREEN allows users to express performance preference through an appropriate extension to Grid submission and description languages such as JSDL and Glue. Operating at intermediate level between applications and Grid middleware, GREEN reduces the gap between users' needs and available resources thus enabling a seamless exploitation of the Grid.

The task management is a critical component for the computational grids. The aim is to assign tasks on nodes according to a global scheduling policy and a view of local resources of nodes. A peer-topeer approach for the task management involves a better scalability for the grid and a higher fault tolerance. But some mechanisms have to be proposed to avoid the computation of replicated tasks that can reduce the efficiency and increase the load of nodes. In the same way, these mechanisms have to limit the number of exchanged messages to avoid the overload of the network.In [4], we have proposed two methods for the task management called active and passive. These methods are based on a random walk: they are fully distributed and fault tolerant. Each node owns a local tasks states set updated thanks to a random walk and each node is in charge of the local assignment. Here, we propose three methods to improve the efficiency of the active method. These new methods are based on a circulating word. The nodes local tasks states sets are updated thanks to periodical diffusions along trees built from the circulating word. Particularly, we show that these methods increase the efficiency of the active method: they produce less replicated tasks. These three methods are also fully distributed and fault tolerant. On the other way, the circulating word can be exploited for other applications like the resources management or the nodes synchronization.
