Abstract:
1. A method of distributing at least one network cryptographic key to a client attempting to access a network via an edge device of said network, the method comprising the steps of: receiving first information from a client, encrypting said first information with a network secret cryptographic key to generate a first cipher, said network secret cryptographic key being known to an edge device of a network and an authentication server but not to said client, sending said first cipher and a network identifier associated with said edge device of said network to said authentication server, receiving a second cipher from said authentication server, decrypting said second cipher with said network secret cryptographic key to obtain a client cryptographic key, encrypting at least one network cryptographic key with said client cryptographic key to generate a third cipher, and forwarding said third cipher to said client.
