Diffie-Hellman key exchange algorithm, which is used in regular scenes base on the discrete logarithm problem, demands that typically two communication parties should struck up a lively conversation leading to a long-term dependable fellowship. A high efficiency the polymorphic key exchange algorithm is proposed that is based on the polymorphic key exchange protocol. The identity information of two parties can be appended to the agreement. Both communication parties use their PRNGs to finish the polymorphic virtual S-box together. The security of the PRNG was analyzed by the Strict Avalanche Criterion and some experimental results. It was proposed that the polymorphic key exchange algorithm can become a broad agreement in irregular scenes. ©2010 IEEE.

Data center facilitates the e-governance system. Data center is a huge repository of data that is required by every stakeholders of e-governance system. It consists of many sensitive governments' data. Access of these data by every authorized stakeholder is one of the mandatory features of data center. At the same time, it has many challenges like the cost, management and updating it and also encounters with many threats from intruders. Providing reliable data to its users in terms of services in low cost is the main objectives of data center. This paper tries to address the challenges with the concept of cloud computing. We discuss the features of cloud computing and its use in data center in this paper.

RFID-based electronic voting: What could possibly go wrong?

RFID-based electronic voting: What could possibly go wrong?

引用

IEEE International Conference on RFID

作者： Yossef Oren Avishai Wool Computer and Network Security Laboratory School of Electrical Engineering Tel-Aviv University Ramat-Aviv Israel

When Israel's Ministry of Internal Affairs decided to move to electronic voting, it chose to replace the traditional paper ballot with secure contactless smartcards. The system was designed around HF RFID technology to make voting stations easier to use and less prone to mechanical faults. However, in doing so the system was exposed to a powerful class of hardware-based attacks called relay attacks, which can extend the interrogation range of HF RFID tags far beyond the nominal range of 5 centimetres. We show how a low-budget adversary armed with a relay device can read out all votes already cast into the ballot box, suppress the votes of one or several voters, rewrite votes at will and even completely disqualify all votes in a single voting station. Our attacks are easy to mount, very difficult to detect, and compromise both the confidentiality and the integrity of the election system.

McAfee securityCenter Firewall is one of the most popular security software installed on millions of Internet connected computers worldwide. ¿McAfee claims that if you have installed McAfee securityCentre with anti-virus and anti-spyware and Firewall version 9.3 then you always have the most current security to combat the ever-evolving threats on the Internet for the duration of the subscription¿. In this paper, we present our findings regarding the effectiveness of McAfee securityCentre software against one of the most popular distributed denial of service (DDoS) attack, namely ping-flood attack on the computer which has McAfee securityCentre installed. The McAfee securityCentre software has an in built firewall which can be activated to control and filter the inbound/outbound traffic. It can also block the ping requests in order to stop or subside the ping based DDoS Attacks. To test the McAfee security Centre software, we created the ping traffic in the controlled lab environment of networking Research Lab here at The University of Texas-Pan American. It was found that the McAfee Firewall software itself was incurring DoS (denial of service) by completely exhausting the available memory resources during its operation of stopping the external ping attack.

Distributed Denials of Service (DDoS) attacks are increasing over the Internet, where the attacker consumes all the resources of the network or the victim computer, thus preventing legitimate users from accessing the services. This paper compares the impact of a DDoS attack, called Land Attack, on popular operating systems such as ¿Windows XP¿, ¿windows Vista¿ and ¿Apple's Leopard¿. We investigate and compare the built-in ability of these operating systems in withstanding land attacks at different loads of Land Attack traffic. In this experiment, we measure the exhaustion of the computing resources, for the above mentioned operating systems under varying loads of the Land Attack traffic. Our results show that Windows XP operating system was most robust, and capable of surviving the ICMP-Land Attack when compared with Windows Vista and Apple's Leopard operating systems.

Apple's iMac computers are promoted by the Apple Inc. to be secure, safe, virus free and fast computers. In this experimental paper, we evaluate the security offered by the iMac computers with its usual Leopard Operating System, against ARP-based flooding attacks in a Gigabit LAN environment. We compared the effect of ARP attacks on Leopard OS against those on the Windows XP-SP2 when installed on the same iMac platform under the same network attack environment. ARP-based flooding attacks can originate in a LAN environment, which can impact a victim computer with a barrage of ARP requests, and there by exhausting resource of the victim computers in processing these requests. To study the impact on iMac computers, we created the ARP traffic in a controlled lab environment to test against iMac computer that first deployed Leopard OS and then later the same iMac platform was made to rather use Windows XP OS. It was found that the Apple's iMac computer using its usual Leopard operating system crashed even under low bandwidth of ARP-based attack traffic, requiring forced reboot of the iMac computer. Interestingly, when compared with Microsoft's Windows XP-SP2 operating system, deployed on the same iMac platform, the computer was able to sustain the attack and didn't crash. Our discovery of this vulnerability shows that Apple's popular operating systems namely Leopards commonly deployed on iMacs are prone to crash under ARP-based security attacks.

Wireless ad hoc networks, especially in the hostile environment, are vulnerable to traffic analysis which allows the adversary to trace the routing messages and the sensitive data packets. Anonymity mechanism in ad hoc networks is a critical securing measure method employed to mitigate these problems. In this paper, we propose a novel secure and anonymous source routing protocol, called SADSR, based on Dynamic Source Routing (DSR) for wireless ad hoc networks. In the proposed scheme, we use the pseudonym, pseudonym based cryptography and the bloom filter to establish secure and anonymous routing in wireless ad hoc networks. Compared to other anonymous routing protocol, SADSR is not only anonymous but also the secure in the routing discover process and data transmission pŕocess.

With the spread use of the computers, a new crime space and method are presented for criminals. Thus computer evidence plays a key part in criminal cases. Traditional computer evidence searches require that the computer specialists know what is stored in the given computer. Binary-based information flow tracking which concerns the changes of control flow is an effective way to analyze the behavior of a program. The existing systems ignore the modifications of the data flow, which may be also a malicious behavior. Thus the function recognition is introduced to improve the information flow tracking. Function recognition is a helpful technique recognizing the function body from the software binary to analyze the binary code. And that no false positive and no false negative in our experiments strongly proves that our approach is effective.

Today, almost all the C2C e-commerce community member reputation evaluating algorithms are time sensitive. The reputation of a community member is accumulated after transactions and the increment of reputation after a successful transaction is computed based on the score given by his or her transaction partner. Since people always tend to do business with those with high reputation value, the reputation of members joined in C2C community at different time will vary greatly although they may provide the same commodity quality and service. It is unfair to new comers. In this paper, we propose a novel algorithm to overcome the shortcoming. Based on the transaction social network, our algorithm employs the random walk strategy to compute member reputation and enhance system fairness. © 2010 IADIS.
