Anonymity Trilemma - Strong Anonymity, Low Bandwidth Overhead, Low Latency - Choose Two
Explore the fundamental constraints of anonymous communication protocols in this IEEE conference talk. Delve into the trilemma of achieving strong anonymity, low bandwidth overhead, and low latency simultaneously. Examine the relationship between these three properties against a global passive adversary. Discover why only two out of the three can be realistically achieved in any given protocol. Investigate further constraints when facing a stronger adversary capable of compromising protocol nodes. Learn about necessary trade-offs between bandwidth and latency overhead to maintain strong anonymity. Gain insights into how prominent anonymous communication protocols measure up against these constraints. Use this analysis as a guideline for improving existing systems and designing innovative protocols with unconventional bandwidth and latency choices.
