Hardware-fault attacks have become a prominent threat against secure cipher implementations. Faults are deliberately introduced during the operation of cryptographic hardware so that, based on the faulty outputs, secret keys may be recovered. This work focuses on the RSA-CRT algorithm, which, although famous and widely exploited, is known to be vulnerable to hardware-fault attacks. Most of the counter...
Among the various forms of malware, botnets are emerging as the most serious threat against cyber-security as they provide a distributed platform for several illegal activities such as launching distributed denial of service attacks against critical targets, malware dissemination, phishing, and click fraud. The defining characteristic of botnets is the use of command and control channels through which...
In P2P networks, an economic measure is efficient to incentivize nodes to provide services to others. As the payment scheme is essential in the economic measure, an efficient and secure payment scheme is our goal. In this paper, we propose a mechanism that requires the nodes first purchase enough trivial scrip and then pay a piece of scrip for each service, such as a file piece (say 256 KBytes) downloading...
