Abstract:
1. A method of providing secure access to a wireless network, the method comprising: generating a plurality of pre-shared keys and a schedule to rotate an active one of the plurality of pre-shared keys at a manager application that resides on a network entity external to a wireless access point that provides access to the wireless network; distributing the plurality of pre-shared keys from the manager application to the wireless access point and a wireless device, wherein the wireless access point and the wireless device encrypt data with the active one of the plurality of pre-shared keys to communicate over the wireless network; provisioning the schedule to rotate the active one of the plurality of pre-shared keys from the manager application to the wireless device, wherein the wireless device uses the schedule provisioned from the manager application to automatically rotate the active one of the plurality of pre-shared keys without further communicating with the manager application or the wireless access point with respect to rotation of the active one of the plurality of pre-shared keys; and communicating, from the manager application to the wireless access point, a plurality of rotation signals that cause rotation of the active one of the plurality of pre-shared keys on the wireless access point, wherein the manager application communicates each of the plurality of the rotation signals synchronously with a passing of a time interval defined in the schedule provisioned to the wireless device.
