Definition:
Onion routing is a method of anonymizing internet communication by encrypting messages in layers and routing them through a network of volunteer-operated nodes (onion routers), making it difficult to trace the original source.
Use Cases:
- Used by individuals seeking privacy or anonymity online, such as journalists or activists.
- Employed in networks like Tor (The Onion Router) to anonymize web browsing and protect against surveillance.

Questions and Answers:
- How does onion routing enhance privacy?
Onion routing encrypts messages in multiple layers and routes them through several nodes, making it difficult for anyone to trace the source or destination of the communication.
- What is the difference between onion routing and a VPN?
A VPN routes traffic through a single server, while onion routing encrypts and routes traffic through multiple nodes for increased anonymity.
- What are the risks of using onion routing?
Onion routing can be slower due to multiple hops, and while it offers privacy, malicious nodes in the network could potentially spy on traffic if not fully encrypted.
