Abstract: A method includes sending a faked authentication request from a client device wherein the faked authentication request includes identification credentials. A faked authentication request indicates that a reply message in response to the faked authentication request is to include data for updating a directory on the client device. A reply message is received at the client device in response to the faked authentication request. The reply message includes data for updating the directory. The directory is updated based, at least in part, on the data for updating the directory.

Abstract: A method of, and system for, changing encryption information in a computer network is provided. The method includes providing at least first cryptographic information and second cryptographic information. A first validity period is provided for the first cryptographic information and a second validity period is provided for the second cryptographic information wherein the first and second validity periods overlap.

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.

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.

Abstract: A method of, and system for, associating a plurality of transaction data records generated in a service access system including a plurality of service providers is provided. The transaction data records are generated in response to a user accessing the system during a single user session. The method includes generating a unique session identification that is uniquely associated with the single user session and which is receivable by the service providers. The unique session identification is included in the transaction data record. The plurality of transaction data records is received at a transaction processing facility from the service providers and processes using the unique session identification of each transaction data record. In certain embodiments, the unique session identification is provided in a user identification string of each transaction data record when the user session is authentication.

Abstract: A method is provided of authenticating a user device requesting access to a computer system. The method includes encrypting current session data at a connection application of the user device via which a user requests access to the computer system, the current session data changing with each user request. The encrypted current session data is then included in user authentication data in an access request which is communicated in plain text which is then decrypted. Reference session data is then compared with the decrypted current session data and the user request is selectively categorized dependent upon the outcome of the comparison.
