A Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks

In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

New Polymers to Protect Space Vehicles

The synthesis and the characterization of new polymeric systems to be used as protective coatings for space vehicles is described. Particular emphasis is placed on ablators which have low irradiation and particle emissivity under the conditions of typical reentry of a space vehicle into the atmosphere. Crosslinking by ionizing radiation in carbon black filled Kel-F and Teflon has been establish...

Steven Emerson Hamas , the PLO , and Terrorist Attacks Against Israel

Last December, Hamas held its annual rally in a Gaza stadium. More than 70,000 people— an overflow audience—attended. As Hamas leaders took the podium one after another, making incendiary speeches against the peace accords and calling for jihad against the Jews, the fervor of the crowd mounted. Cries of “Allahu Akbar! [God is great]” and “Mawt lil-Yahud! [Death to the Jews]” greeted the speaker...

Using Modular Extension to Provably Protect ECC Against Fault Attacks

Fault injection attacks are a real-world threat to cryptosystems, in particular asymmetric cryptography. In this paper, we focus on countermeasures which guarantee the integrity of the computation result, hence covering most existing and future faults attacks. Namely, we study the modular extension protection scheme in previously existing and newly contributed variants of the countermeasure on ...
