PAPER
LAMP: Lightweight Approaches For Latency Minimization In Mixnets With Practical Deployment Considerations

Mixnets are a type of anonymous communication system designed to provide network privacy to users. They route client messages through multiple hops, with each hop (mix) perturbing the traffic patterns, thus making message tracing difficult for a network adversary. However, privacy in mixnets comes at the cost of increased latency, limiting the applications that are usable when accessed through a mixnet. In this work we present LAMP, a set of routing approaches tailored for minimizing the propagation latency in mixnets with minimal impact on anonymity. The design of these approaches is grounded in practical deployment considerations making them lightweight, easy to integrate with existing deployed mixnets and computationally realistic. We evaluate the proposed approaches using latency data from the deployed Nym mixnet and demonstrate that LAMP can reduce latency by a factor of 7.5 (from 153.4ms to 20ms) while maintaining high anonymity. LAMP even outperforms the state-of-the-art system LARMix, providing 3× better latency-anonymity tradeoffs and significantly reducing the computational overhead by ≈ 13900× in comparison to LARMix.

ABOUT NDSS
The Network and Distributed System Security Symposium (NDSS) fosters information exchange among researchers and practitioners of network and distributed system security. The target audience includes those interested in practical aspects of network and distributed system security, with a focus on actual system design and implementation. A major goal is to encourage and enable the Internet community to apply, deploy, and advance the state of available security technologies.

Executive Summary Modern cyberattacks rarely appear as a single, obvious incident. Instead, they manifest as multiple low-level signals across web, endpoint, DNS, cloud, and network telemetry. When analyzed in isolation, these signals may seem benign. When correlated intelligently, they reveal active attack campaigns targeting applications, identities, cloud storage, and network boundaries. This article presents a

Holiday phishing is not a “carelessness” problem. It’s a timing problem. One rushed click can have outsized consequences: a stolen password, a compromised account, or malware installed in seconds. During the holidays, attackers count on high volumes of shipping notices, receipts, and travel updates to make a fake message feel ordinary.
