“…Thus attacks, such as denial-of-service and storage overflow, may occur to the exposed node, whether it is malicious or not. [7,8] The existing techniques to secure anonymity include MUTE [10], Onion Routing [12,13], Crowds [11] and Mantis [9]. In order for MUTE to protect anonymity, file share is made through other clients such as jondo.…”

Basically flooding-based P2P systems provide anonymity and thus it is not possible to find the initial sender of packet and the designated receiver of that packet. However it does not provide anonymity where the IP addresses of nodes uploading and downloading contents are revealed. So in order to maintain anonymity we propose and test our techniques that the receiver node of response packets on retrieval query is agent node and the agent node provides contents service between server and client. Through the proposed techniques it was found that the identity of node is secured without using encryption techniques which have been deployed in the former anonymity protection techniques and control data communications through all the nodes located between server and client. The application of this concept of which result was evaluated may be extended to many other current P2P systems under operation.

This paper considers a type of application-level DDoS attacks aiming at search engines. The attackers issue search requests randomly drawn from a predefined word pool. Without any detection mechanism, a search engine can become quite unusable given enough attackers. We design a scheme to counter these attacks. Then, we evaluate the performance of the scheme. We also study the false positive and false negative ratios yielded by the scheme. Keywords-DDoS, application level security, request queueI.

“…In P2P systems, much work has been focusing on routing efficiency and scalability [4] and some areas of security such as secure routing [5] and DOS (denial of service) attacks [6]. In the active worm area, much work has been done in worm modeling such as the computer virus model [7], active worm spreading model [8], and Code-Red worm model [1].…”

Recent active worm propagation events show that active worms can spread in an automated fashion and flood the Internet in a very short period of time. Due to the recent surge of Peer-to-Peer (P2P) systems with large numbers of users, P2P systems can be a potential vehicle for the active worms to achieve fast worm propagation in the Internet. In this paper, we address the issue of the impacts of active worm propagation on top of P2P systems. In particular: 1) we define a P2P system based active worm attack model and study two attack strategies (an off-line and on-line strategy) under the defined model; 2) we develop an analytical approach to analyze the propagation of active worms under the defined attack models and conduct an extensive study to the impacts of P2P system parameters, such as size, topology degree, and the structured/unstructured properties on active worm propagation. Based on numerical results, we observe that a P2P-based attack can significantly worsen attack effects (improve attack performance), and we observe that the speed of worm propagation is very sensitive to P2P system parameters. We believe that our work can provide important guidelines in design and control of P2P systems as well as overall active worm defense.
