Abstract. We study large-scale distributed cooperative systems that use optimistic replication. We represent a system as a graph of actions (operations) connected by edges that rei...
Current trends in high-performance parallel computers show that fat-tree interconnection networks are one of the most popular topologies. The particular characteristics of this to...

Focused around the field of the exploitation and the administration of high performance large-scale parallel systems , this article describes the work carried out on the deployme...
We present a novel technique to secure the execution of a processor against the execution of malicious code (trojans, viruses). The main idea is to permute parts of the opcode val...
Security in wireless ad hoc networks is hard to achieve due to the vulnerability of its links, limited physical protection, and the absence of a centralized management point. Cons...
