Abstract:
1. A system for establishing secure, authenticated communications in a data network, comprising: a first key server, said first key server having an associated first server public key and at least a second server public key of a second key server of said data network; and a client in communication with the first key server, said client comprising: wherein said security module compares the preprogrammed authorization data of the first server public key of the first key server with an authorization data calculated from a public key received from the untrusted local host; wherein if the first server public key of the first key server matches the public key received from the untrusted local host, then the first key server is an authorized key server; wherein secure communications between said authorized key server and said client are established using a secure handshake process; and wherein by said establishment of said secure communication between said authorized key server and said client, said client is configured to establish said secure, authenticated communications in said data network with the second key server based on at least the second server public key received via the secure communications from said authorized key server.
