Distributed Software-Based Attestation for Node Compromise Detection in Sensor Networks

Overview Sensors that operate in an unattended, harsh or hostile environment are vulnerable to compromises because their low costs preclude the use of expensive tamper-resistant hardware. Thus, an adversary may reprogram them with malicious code to launch various insider attacks. Based on verifying the genuineness of the running program, the paper proposes two distributed software-based attestation schemes that are well tailored for sensor networks. These schemes are based on a pseudorandom noise generation mechanism and a lightweight block-based pseudorandom memory traversal algorithm.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
