The replication and dissemination of multimedia data become increasingly convenient and efficient, so a lot of redundant multimedia data, especially image files, have been generated and stored on the Internet. Therefore, it is necessary to perform deduplication of images. However, the existing deduplication methods of regular files are hash-based, which cannot be applied to the deduplication of images...
The rapid adoption of cloud services has propelled network data sharing and storage. Client-side deduplication is proposed to minimize bandwidth and space needed to upload and store duplicated data. The existing solutions, however, were recently found to be vulnerable to attacks that enable the attackers to get full access to the entire file stored on the server after learning just a small piece of...
In this paper, we consider the problem of “evil twin” attacks in wireless local area networks (WLANs). An evil twin is essentially a rogue (phishing) Wi-Fi access point (AP) that looks like a legitimate one (with the same SSID). It is set up by an adversary, who can eavesdrop on wireless communications of users' Internet access. Existing evil twin detection solutions are mostly for wireless network...
Denial of Service (DoS) and distributed denial of service attack (DDoS) is now a common means of attack that affects seriously network security and the quality of online services. This paper analyzes the DoS (DDoS) attack prevention principles and gives an thorough analysis of existing prevention techniques, proposed to prevent DoS (DDoS) attacks in three ways: using a router DoS attack prevention,...
