This is a Plain English Papers summary of a research paper called or follow me on is a system that provides a way for people to access the internet without their internet service provider (ISP) or government being able to block or censor the websites they visit. It does this by using a special type of DNS server called a "DoH" server, which encrypts the requests to hide what websites are being accessed.
To make it harder for the ISP or government to block the DoH server, NinjaDoH constantly changes where the server is located and what its identity is. It does this by using the power of big cloud computing providers (called "hyperscalers") and a technology called IPNS, which allows the server's location and identity to be dynamically updated.
By constantly moving the DoH server around and changing its identity, NinjaDoH aims to stay one step ahead of any attempts to censor or block it, providing a more censorship-resistant way for people to access the internet.
Key Findings
- NinjaDoH can dynamically deploy DoH servers across multiple hyperscaler cloud providers to create a "moving target" defense against censorship
- The use of IPNS allows the DoH server's location and identity to be updated frequently, making it harder to block
- Experiments show NinjaDoH has low overhead and can effectively circumvent censorship attempts compared to a static DoH server
Technical Explanation
NinjaDoH is designed to provide a censorship-resistant DoH server by leveraging the scalability and flexibility of hyperscaler cloud providers and the InterPlanetary Name System (IPNS). The key technical elements include:
: NinjaDoH dynamically deploys DoH servers across multiple hyperscaler cloud providers. The server's location and identity are updated frequently using IPNS to create a "moving target" defense.
presents a novel approach to building a censorship-resistant DNS infrastructure by leveraging cloud computing and decentralized technologies. By dynamically deploying and relocating DoH servers, NinjaDoH aims to stay one step ahead of censorship attempts, providing a more resilient way for people to access the open internet. While further research is needed to address potential limitations, this work represents an important step towards enhancing internet freedom and circumventing online censorship.
