Noise Generating Mixnet

Noise-Generating Mixnets (NGM) protect not just content, but also patterns of behaviour online. It obfuscates both data and metadata of communication.

The NymVPN is the first commercial application to include an NGM offering protection against AI-surveillance. The network can also be integrated to any blockchain, wallet, or app to provide network layer privacy protection.

    Key Features

    5-hop mixnet

    Data sent via the mixnet to any web application travels 5-hops, before arriving at its destination. Between an Entry Node and an Exit node, three layers of mixnodes guarantee metadata obfuscation.

    Nested encryption

    At each subsequent hop, the data packets are encrypted so each node only has information about the packet's origin and destination but not the payload (data) itself.

    Zero knowledge access credentials

    When a Nym Client connects to the mixnet, the Entry Gateway performs the check for a zero-knowledge network access credential, making users un-linkable to their internet usage.

    Cover traffic

    Empty data packets are introduced into the network to increase the anonymity of all users. These dummy packets look just like real ones.

    Traffic mixing

    Anonymized data packets from different users are shuffled together by mix nodes to obscure patterns of communication across the network.

    Timing obfuscation

    Data mixing prevents surveillance from tracking your packets based on the timing of when they arrive on and leave a server.

    Using the Mixnet

    Individuals:

    You can simply get the NymVPN app to start benefiting from the secure routing offered by the Nym network. The app allows people to choose between two network modes:

    • Fast Mode (decentralized 2-hop), optimized for browsing and streaming
    • Anonymous Mode (a 5-hop NGM) optimized for anonymity and best for messaging, crypto transactions, email, and other activities that can tolerate high latency.

    Enterprise:

    For companies seeking to offer superior security and integrity to their customers, the Nym network can be used as a general purpose secure routing network. Nym can be integrated directly with applications and services to secure the integrity of users and systems by providing secure routing for any app, blockchain, or service. Integrations currently in progress include z-cash light clients to protect crypto transactions and Ethereum validators to secure the integrity of consensus and protect against MEV attacks. Contact us at: contact@nym.com.

    Decentralization of the mixnet improves its fundamental privacy properties like ensuring that users are not directly connected to their online interactions.

    Decentralization ensures that the full route of a user’s traffic can never be known by any single entity handling user data, and makes external surveillance very difficult to achieve.

    Decentralization requires a minimum of 2 intermediary servers (or hops) between a user and the web. The large majority of VPNs are centralized. With NymVPN, there is no single entity on the network, not even Nym, where your full traffic is logable. Nym is a zero-knowledge network by design.

    A Noise Generating Mixnet (NGM) is a new technology for secure internet traffic routing, developed specifically for the growing challenges posed by AI and malicious government surveillance programs. A NGM protects not just the content of messages but also the metadata and patterns of communication across the internet. 

    A NGM performs best in class (over VPNs and Tor) against: 

    • Traffic analysis
    • End-to-end correlation attacks
    • Website fingerprinting
    • Protecting your traffic from a global passive adversary able to watch the entire network.

    It does this by introducing “noise” into the network to protect users’ metadata and obscure their patterns of communication. On Nym’s NGM, noise includes uniform packet sizes, cover traffic, packet mixing, and timing obfuscation. Network noise makes it so everyone’s traffic cannot be analyzed and used by fraudsters, hackers, and malicious actors to perform a variety of attacks.

    The speed of the Nym network depends on your choice of routing. Through NymVPN, the normal 2-hop (WireGuard) mode has speeds up to 100 Mbps and latency around 50 ms depending on your chosen gateways. This is ideal for things like browsing and streaming.

    For maximal anonymity protections , the Anonymous Mode will involve more latency but with advanced protections against surveillance. It is thus recommended for highly sensitive traffic which can tolerate high latency like messaging, crypto transactions, and email.

    For end users you can use the Nym NGM via the NymVPN. NymVPN has three plans available: a monthly plan of $11.99, or discounted plans of 1- or 2-years. See Nym’s pricing pages for all the details.

    For enterprise Any app, wallet or blockchain can integrate with the Nym NGM to secure traffic of users, light clients and validators. For more information on how to integrate and partner with Nym, reach out to: sales@nymte.ch
