Title: Method and apparatus for providing dynamic traffic control within a communications network
Inventor: NGUYEN HAN Q
IPC: H04L69/14
Filed: 2006-03-08
Abstract: A method and apparatus for providing traffic management through dynamic and granular definitions of route groups. Within a communications network, a traffic routing control unit (e.g., an intelligent route service control point (IRSCP)) creates route group assignments for each route within a customers network in accordance with a customer's routing plan, determines protocol control values to be set within each edge router of the network to fulfill the group assignments, and uses border gateway protocol (BGP) to set the protocol control values in the edge routers to facilitate fulfilling the route group assignments. Using the traffic routing control unit and programming the protocol control values of the edge routers, enables the network to be flexibly defined and the traffic routing within the network to have very granular control.

Title: System and method for protecting a password against brute force attacks
Inventor: KIRKUP MICHAEL G
IPC: H04L9/14
Filed: 2006-10-31
Abstract: In a system and method for authenticating a client device by an authentication device, the client device user is assigned a PIN generated by the authentication device. The user provides the PIN and a password to the client device, from which the client device generates a symmetric key and further generates a public/private key pair. The private key is encrypted using the symmetric key and stored in encrypted form only. The public key and a message authentication code generated from the PIN  are provided to the authentication device, which stores the public key.  Subsequently, when the user seeks to be authenticated, the user enters a password at the client device, which is used to generate a symmetric key to decrypt the encrypted private key. A message to the authentication device is signed using the resultant value. The authentication device uses the public key to verify the signature of the message.
