| dc:description | The Router at the head of a transmission selects a number of Onion Routers at random and generates a message for each one, providing it with symmetric keys for decrypting messages, and instructing it which Router will be next in the path. Each of these messages, and the messages intended for subsequent routers, is encrypted with the corresponding Router's public key. This provides a layered structure, in which it is necessary to decrypt all outer layers of the onion in order to reach an inner layer. (Wikipedia) |
