aDTN - Undetectable Communication in Wireless Delay-tolerant Networks (Working Draft)
This addresses privacy concerns for users in wireless ad-hoc networks, but it appears incremental as it adapts existing mix network concepts to a wireless broadcast context.
The paper tackles the problem of protecting user privacy in wireless ad-hoc networks by proposing a delay-tolerant communication system that makes communication undetectable, achieving undetectability for all users and messages against external adversaries and for non-compromised groups against internal adversaries, assuming encryption is not broken.
This document describes a best-effort delay-tolerant communication system that protects the privacy of users in wireless ad-hoc networks by making their communication undetectable. The proposed system is a wireless broadcast-based adaptation of mix networks where each user belongs to at least one group it trusts, and each group acts as a mix node. Assuming encryption is not broken, it provides undetectability of all users and messages against external adversaries, as well as undetectability of users and messages in non-compromised groups against internal adversaries.
