One of the key issues with the practical applicability of Proof-Carrying Code (PCC) and its related methods is the difficulty in communicating and storing the proofs which are inherently large. The approaches proposed to alleviate this, suffer from drawbacks of their own especially the enlargement of the trusted computing base, in which any bug may cause an unsafe program to be accepted. We propose...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
This paper investigates and simulates a coloured stochastic Petri nets model for depth evaluation intrusion detection. Network attack behaviors are very complexity sometimes, it is difficult to capture all of them. In this paper, we could realize what them happened with analyzing and simulating an intrusion. The experimental results demonstrated that the CSPN model approach was an efficient and helpful...
Packet sampling supports a range of Internet measurement applications including characterizing the spatial flow of traffic through a network for traffic engineering purposes, identifying the flows utilizing a link for billing purposes or for intrusion detection, and monitoring end-to-end data-path quality. However, packet-sampling mechanisms must be robust to adversarial hosts that craft packet streams...
