In this task you have to do two main things. They are bound together, but presented separately for the sake of clear presentation: a) Implement a network protocol which provides both secrecy and lefts behind a “prove?? in the form of signature b) Register your own personal official key certificate on the key server, get another certificate, receive a document and sign for it. Receive and signing for received document are done with network protocol from a). The received document will be generated uniquely for each student and is counted as a part of submission. Here you have to do an official key distribution in a very specialized way. That means that the keys must be signed by those who “own?? them, i.e. the owners who have the access to the private keys, and that there is public common place to leave and pick up those keys (i.e. this requires a key server, that we will provide for testing).
