Even though existing P2P protocols were not immediately usable for N2N without modification, some concepts already present in other P2P architectures [16] have been utilised as is explained in the following chapter. In addition to the properties listed so far, N2N presents further differences from other approaches [28] [29] [30]:…”

Abstract. The Internet was originally designed as a flat data network delivering a multitude of protocols and services between equal peers. Currently, after an explosive growth fostered by enormous and heterogeneous economic interests, it has become a constrained network severely enforcing client-server communication where addressing plans, packet routing, security policies and users' reachability are almost entirely managed and limited by access providers. From the user's perspective, the Internet is not an open transport system, but rather a telephony-like communication medium for content consumption. This paper describes the design and implementation of a new type of peer-topeer virtual private network that can allow users to overcome some of these limitations. N2N users can create and manage their own secure and geographically distributed overlay network without the need for central administration, typical of most virtual private network systems.

Abstract-Most network attackers perform port scanning individually, without synchronization, to find victim hosts. Such port scanning schemes suffer from two problems: first, there are too many duplicate scannings and too much contention among different port scanners; second, a complete port scanning takes a long time to finish.In this paper, we present a fast DHT-based collaborative port scanning scheme that aims to eliminate duplicate scanning, minimize contention, and significantly increase the scanning speed. In collaborative attacks, attackers communicate and collaborate with each other to launch much more powerful attacks. In the DHT-based collaborative port scanning scheme, attackers collaborate to search the network for ports that could be exposed to attacks.We propose different collaborative scanning strategies and analyze their advantages and disadvantages. We discuss the static, dynamic, and hybrid target selection and allocation schemes. We present the algorithm details and discuss the stop and revisit policy for the collaborative port scanners. We conduct experiments to evaluate the performance and overhead of the collaborative port scanning strategies. Experimental results suggest that the proposed collaborative port scanning system significantly increases the efficiency of port scanning and provide insights into many design and implementation issues.
