Abstract

We propose a method that provides information-theoretic security for client-server communications. An appropriate encoding scheme based on wiretap codes is used to show how a client -server architecture under active attacks can be modeled as a binary-erasure wiretap channel. The secrecy capacity of the equivalent wiretap channel is used as a metric to optimize the architecture and limit the impact of the attacks. We also provide a method to design attack-resistant client-server architectures that are resilient and secure using wiretap codes. Specifically, the objective is not only to ensure reliable communication between client and servers in the presence of disrupted nodes, but also to guarantee that a malicious attacker hacking the packet information at compromised nodes is unable to retrieve the content of the message being exchanged. In principle, standard encryption techniques could be implemented to ensure secure communication between client and servers; however, instead of using traditional cryptographic tools to encrypt information contained in the packet, the proposed approach exploits the fact that the attacker only gets parts of the packets sent by the client. we define wiretap model as a java web application security framework in order to solve web application vulnerabilities. Wiretap model extends web application’s behavior by adding security functionalities maintaining the API and the framework specification. The security functionalities include Integrity, Editable data validation, Confidentiality, Anti-CSRF token.

Abstract

Dynamic Parallel Chunk Switching (DPCS) scheme effectively minimizes the average download time in P2P network, P2P is popularized by file sharing applications, but the average download time in P2P network is more due to different source peers have different service capacity and fluctuations of service capacity in single source peer. Our method DPCS can removes effect of these negative factors, thus the download time is decreases. And we show that our method performs better than other algorithms which are in use through the simulation. The minimizing the average download time is increases the efficiency of the network.
