Onion routing and regular routing are two different types of routing techniques. Regular routing is the traditional way of routing data packets through a network. It involves sending a packet of data from one node to the next, until it reaches its destination. The main advantage of regular routing is that it is relatively simple and efficient.

Onion routing, on the other hand, is a more secure form of routing data packets. It uses a technique known as “layered encryption” which means that each layer of the packet is encrypted with a different key. This ensures that each node in the network will only be able to decrypt the layer of the packet that it is responsible for. As a result, the identity of the sender and receiver is kept secret, making it much harder for someone to intercept and read the data.

The main difference between onion routing and regular routing is that onion routing is much more secure and anonymous. Regular routing does not provide any protection against attackers and anyone can easily trace the data packets back to the source. Onion routing, on the other hand, provides a high level of security and privacy to the users. By using layered encryption, it makes it much harder for attackers to access the data and trace the packets back to their source.
