  • Patent number: 7958352
    Abstract: A system and method is provided to verify configuration of a client access device requesting access to a network by establishing a communications link between a network access system and the client access device to authenticate and authorize the client access device and a user associated with the client access device. The network access system further receives client device configuration data from the client access device over the communications link during an authentication and authorization exchange and processes the client device configuration data to determine if the client access device will be granted access to the network.

  • Patent number: 7921290
    Abstract: A method is provided to securely authenticate user credentials. The method includes encrypting a user credential with a public key at an access device wherein the public key is part of a public/private key pair suitable for use with an encryption algorithm. The encrypted network user credential is transmitted from the access device to a decryption server where it is decrypted with a private key, the private key being part of the public/private key pair suitable for use with the encryption algorithm. The decrypted user credential is then transmitted from the decryption server to an authentication server for verification. The decryption server typically forms part of a multi-party service access environment including a plurality of access providers, the method including decrypting the user credential of a user proximate an access provider associated with the user credential.
