Onion-Routing Project

The project is to implement 2 peers (Alice and Bob) and a set of intermediary relays (R1, R2, R3, etc...) and implement a more easy approach of ToR-like protocol between them. The messages flowing from Alice to Bob will make use of these relays in a random way and will cipher the communication in order to provide content protection and anonymity. The programming language should be python (version3). The project is divided in 4 steps : 1. implement the relays 2. randomize the routing 3. secure the communications on each link by building a shallot 4. relaying the messages The tor-like network uses several relays to route a message from Alice to Bob. The path is randomized in order to minimize the risks of interception and to increase the anonymity. The confidentiality of the shallot network is implemented as folllows: the relay nodes are unable to decrypt the original message. They can only know about the next hop in the route and the (ciphered) message they have to relay. Alice picks up the route so that it can never be predicted by the relays.
