“…(1)Source nodes' location privacy protection Several schemes dealing with the source nodes' location privacy can be found in [2,4,[14][15][16][17][18][19][20][21][22]. For example, Kamat et al [4] proposed the phantom flooding protocol transmission of a packet to defend against an external adversary.…”

Traditional encryption and authentication methods are not effective in preserving a sink's location privacy from a global adversary that is monitoring the network traffic. In this paper, we first propose a novel anti-traffic analysis (ATA) method to preserve the sink's location privacy. In order to confuse a local or global adversary, each node generates dummy messages, the number of which is dependent on the number of the node's children. Hence, ATA is able to prevent the adversary from acquiring valuable information on the sink's location through the traffic analysis attack. However, a larger number of dummy messages lead to consumption of extra energy. Then, we design our improved ATA (IATA) in such a way that we select some sensors to act as fake sinks, to ensure that sensors around fake sinks generate dummy messages and discard received dummy messages. Since the problem of the optimal fake sinks' placement is nondeterministic polynomial time (NP)-hard, we employ local search heuristics based on network traffic and security entropy. Performance analysis of the ATA scheme can protect the sink's location privacy, and IATA scheme can reduce energy consumption.

“…In this scheme, a path is pre-computed at the source and the data packet is encrypted in multiple layers with the public key of the forwarding node along the path to destination in a sequential order and each node removes their layer of encryption after receiving the packet and forward the remaining packet called the onion to the next hop and finally the decrypted data with all the layers of encryption removed, received by the des-tination. The work in [11] resorts to a quan-titative approach towards privacy. Authors in [12] specifically approach provisions for pri-vacy preservation but lack efficiency of gains achieved from the network coding.…”

This paper presents a novel scheme that provides high level of security and privacy in a Wireless Mesh Network (WMN). We combine an approach of Network Coding with multiple layered encryption of onion routing for a WMN. An added superior feature provides higher level of security and privacy. Sensitive network information is confined to 1-hop neighborhood which is available anyways in a wireless medium with nodes using a bivariate polynomial. The only routing information divulged to a relay node is about next hop. No plain text is ever transmitted and all data can only be decrypted by its source and destination.Prior work finds it difficult to enforce encryption with network coding without divulging in complete routing information,hence losing privacy and anonymity. We compare our scheme with other existing approach for several networks. The preliminary results show this work to provide superior security and anonymity at low overhead cost.

“…They further propose a scheme to provide source location privacy through routing to a randomly selected intermediate node and a network-mixing ring [15]. Although these two schemes can provide comparable source privacy, the first scheme brings another problem of handling the selection of the AS (ambiguity set), while the second scheme again involves taking a random walk.…”

Providing source privacy is a critical security service for sensor networks. However, privacy preserving in sensor networks is a challenging task, particularly due to the limited resources of sensor nodes and the threat of node capture attack. On the other hand, existing works use either random walk path or fake packets injection, both incurring tremendous overhead. In this work, we propose a new approach, which separates the sensor nodes into groups. The source packet is randomly forwarded within and between the groups with elaborate design to ensure communication anonymity; furthermore, members of each group exchange encrypted traffic of constant packet length to make it difficult for the adversary to trace back. One salient feature of the proposed scheme is its flexibility of trading transmission for higher anonymity requirement. We analyze the ability of our proposed scheme to withstand different attacks and demonstrate its efficiency in terms of overhead and functionality when compared to existing works.
