Relationship of Various Occlusal Landmarks to the Occlusal Plane. Relation of Various Extra-Oral and Intra-Oral Soft Tissue Landmarks to the Occlusal Plane - A Study in Dentulous Subjects

If Amoeba actually worked as described above, it would be possible for an intruder to impersonate a server just by doing a get_request on the server's port. These ports are public after all, since clients must know them to contact the servers. Amoeba solves this problem cryptographically. Each port is actually a pair of ports: the get-port, which is private, known only to the server, and the put-port, which is known to the whole world. The two are related through a one-way function, F, according to the relation The one-way function is in fact the same one as used for protecting capabilities, but need not be since the two concepts are unrelated. When a server does a get_request, the corresponding put-port is computed by the kernel and stored in a table of ports being listened to. All trans requests use put-ports, so when a packet arrives at a machine, the kernel compares the put-port in the header to the put-ports in its table to see if any match. Since get-ports never appear on the network and cannot be derived from the publicly known put-ports, the scheme is secure ...»
