SurePath: An Approach to Resilient Anonymous Routing
نویسندگان
چکیده
Current anonymous systems either use a small, fixed core set of mixes or randomly choose a sequence of peer nodes to form anonymous paths/tunnels. The resulting paths are fragile and shortlived — that is, a path fails if one of the mixes/nodes fails or leaves the system. In this paper, we propose SurePath, a failure-resilient tunneling approach for anonymity built on distributed hash tables (DHTs). SurePath aims to make anonymous tunnels fault-tolerant to node failures. The basic idea behind SurePath is to decouple anonymous tunnels from “fixed” nodes and form anonymous tunnels from dynamic mix nodes by relying on DHT routing infrastructure and data replication mechanism. We have implemented SurePath in Java on FreePastry 1.3. We also provide analysis of anonymity and performance evaluation for SurePath.

A Resilient P2P Anonymous Routing Approach Employing Collaboration Scheme
Node churn is a hindrance to construction of P2P-based anonymous networks, which makes anonymous paths fragile and results in message losses and communication failures. A collaboration scheme combining Friendly Neighbor-based Incentive (FNI) and Re-encryption mechanism is proposed to deal with the high node churn characteristic of P2P networks. The FNI mechanism encourages peers to forward othe...
متن کاملLow Latency High Bandwidth Anonymous Overlay Network with Anonymous Routing
Most existing anonymous networks focus on providing strong anonymity for the price of having lower bandwidth, higher latency and degraded usability when compared with the conventional use of the Internet. They also often anonymize only a few specific applications. In this paper, we propose a new approach of constructing an anonymous network. The network consists of an overlay network, which pro...

To provide effective communication in the wireless mesh network (WMN), several algorithms have been proposed. Since the possibilities of numerous failures always exist during communication, resiliency has been proven to be an important aspect for WMN to recover from these failures. In general, resiliency is the diligence of the reliability and availability in network. Several types of resilienc...

متن کاملResilient Multi-path Routing Based on a Biological Attractor Selection Scheme
In this paper we propose a resilient scheme for multi-path routing using a biologically-inspired attractor selection method. The main advantage of this approach is that it is highly noise-tolerant and capable of operating in a very robust manner under changing environment conditions. We will apply an enhanced attractor selection model to multi-path routing in overlay networks and discuss some g...
