Preventing encrypted traffic analysis
… security. Existing mechanisms for preventing traffic analysis focus on re-routing and padding. These prevention techniques have considerable resource and overhead requirements. Furthermore, padding is easily detectable and, in some cases, can introduce its own vulnerabilities. To address these …

Timing channels in traffic analysis
… problems abstracted from practices of network traffic analysis. The first timing channel exists in a router receiving packets from two users; due to the sharing of router buffer, queuing delays of one user's packets incidentally convey information about the other user's packet arrival pattern. …

Neyman-Pearson Decision in Traffic Analysis
The increase of encrypted traffic on the Internet may become a problem for network-security applications such as intrusion-detection systems or interfere with forensic investigations. This fact has increased the awareness for traffic analysis, i.e., inferring information from communication patterns …

Understanding information seeking behavior through network traffic analysis
Many of today's information workers use the Internet as a valuable first-choice source for new knowledge. As such, Internet based information seeking is a key part of how information workers find information. This study develops techniques to quantify the information seeking patterns of information …

Detecting Hidden Wireless Cameras through Network Traffic Analysis
… that will recognize the camera's network traffic characteristics. We monitor the network traffic within the immediate area using a separately developed packet sniffer, a program that observes and collects information about network packets. We analyze and classify these packets based on how …

Integrated traffic analysis and visualization for future road events
The existing traffic simulation methods are limited to specific synthetic scenarios. In addition, the natural structure of traffic and accident data requires modeling the dependent observations on multiple levels. Therefore, a system that utilizes hierarchical LMMs and GBM models are proposed which …

Game traffic analysis and simulation in first person shooter environment
… was disadvantaged due to larger delay. Network traffic for such games was analysed using packet size and inter-packet time metrics fitting a statistical model. However, no research explored the relation between “clean” and “interfered” traffic, only Joyce (2000), Bangun (2000), Jehaes (2003) and …

Conformance testing of peer-to-peer systems using message traffic analysis
… and observed behaviors. The focus on message traffic allows MCTAMA to be used at multiple stages of development and deployment while not being affected by the variations in the operating environment, availability of source code or the capabilities of a monitoring mechanism. As a part of …

Design, analysis, and implementation of effective network flow watermarking schemes
… an extra/different layer of encryption to the traffic payload. As a result, in such applications it is infeasible to link network flows by correlating their packet headers and payloads. Traffic analysis is a powerful tool in this scenario, as it correlates network flows based on their …

Vuvuzela : scalable private messaging that hides metadata
… about who is communicating in the face of traffic analysis. Systems that offer strong privacy guarantees, such as Dissent [39], scale to only several thousand clients, because they use techniques with superlinear cost in the number of clients (e.g., each client broadcasts their message to …

Fully automatic vision-based system for vehicle crash prediction and recognition
… Therefore, it is no surprise that automated traffic analysis systems generate a supreme amount of interest. Despite the rapid advances in technology today, many traffic monitoring systems require substantial amounts of careful annotation. As such, a fully automated traffic analysis system …

Location Privacy In Emerging Network-Based Applications
… be subject to unintentional disclosure through traffic analysis by the attacker. In vehicular networks, authentication leaves a trail to tie a driver to a sequence of time and space coordinates. In a cloud-based navigation system, the location information of a sensitive itinerary is disclosed. …

Riffle : an efficient communication system with strong anonymity
… anonymous communication, but is susceptible to traffic analysis attacks. Designs based on DC-Nets, on the other hand, protect the users against traffic analysis attacks, but sacrifice bandwidth. Verifiable mixnets maintain strong anonymity with low bandwidth overhead, but suffer from high …

Multi-party and distributed private messaging
… methods leak metadata or are susceptible to traffic analysis in spite of end-to-end encryption. Vuvuzela is a foundational private messaging system helps reconcile these two concerns. This project builds on Vuvuzela by introducing three group messaging models. These models tradeoff support …

Enhancing DNS data exfiltration protection through SDN data plane programming
… that could be handled with proper traffic monitoring. In this thesis, the advantages of software-defined networking (SDN) and data plane programming are identified and leveraged to detect DNS-based data exfiltration attacks, including DNS-over-HTTPS. A DNS traffic analysis tool has …

A distributed metadata-private messaging system
… Scalable systems such as Tor are susceptible to traffic analysis. In contrast, the largest-scale systems with metadata privacy require passing all messages through a single server, which places a hard cap on their scalability. This paper presents Stadium, the first system to protect both messages …
