Secure method of neighbor discovery over a multiaccess medium
First Claim
1. An apparatus for communicating to a station in a communication network addresses of other stations within said communication network which said station is capable of communicating with directly, said other stations being referred to as neighbors of said station, said apparatus comprising:
- means for implementing a message protocol for exchanging identifying messages between said station and said neighbors of said station to identify said neighbors to said station;

Abstract
A secure arrangement in which stations in a communications network are informed of the addresses of their neighbors by means of identifying messages transmitted by the stations. To prevent the insertion of illegitimate stations into the network, the system makes use of passwords included in the station-identifying messages. In networks where eavesdropping is possible, the passwords are encrypted versions of the identities of the stations transmitting the messages and in systems where stations can also be impersonated, the encrypted passwords also include time stamps.
