Objective of this paper
This paper describes the mechanisms to efficiently store source routes anonymously, and to forward data packets anonymously. A key management mechanism is described in order provide strong anonymity for end-to-end communications. Performance comparison between ODAR and AODV indicates ODAR has comparable control overhead to AODV.
Anonymity Goals
This paper intends to provide the following anonymities in ODAR:
Identity anonymity: A node receiving or sending data packets cannot be identified by its neighbors. It is computationally difficult for adversaries to search and determine the node's true identity.
Route/path anonymity: A node forwarding packets must not be able to infer the identities of other nodes that also participate in the data forwarding.
Topology/location anonymity: Routing information maintenance does not reveal the distance, neighbor link information of a node, nor the true routing path or tree information. Neither can they be deduced from routing information in the packets.
DESIGN GOALS
I) Ensure Privacy
Identity Privacy:It consists of the following requirements:
(a) No one knows the real identities of the source and the destination, except themselves;
(b) the source and the destination have no information about the real identities of intermediate nodes en route.
Future work of this paper
In the future, plan to study the impact of our “test suite” on the performance of other ad hoc network protocols like multicast ad hoc, geographic routing protocols.
This study would help to understand the impact of mobility more deeply and clearly. Several parameters such as traffic patterns, node density and initial placement pattern of nodes may affect the routing performance and need to investigate them further.
Anonymous Secure Routing in Mobile Ad-Hoc Networks
In this paper, first define more strict requirements on the anonymity and security properties of the routing protocol in mobile ad-hoc networks.
Following that, proposes the Anonymous Secure Routing (ASR) protocol that can not only protect the privacy of nodes and routes, but also ensure the security of discovered routes.
Afterwards, detailed analysis is given to show that ASR can ensure anonymity and security of the routing protocol against known passive and active attacks.
