Abstract
A data processing system and method are disclosed for protecting data stored on a device included within the system. A device key pair is established which identifies a particular device included within the system. The device key pair includes a device public key and a device private key. The device includes data stored on the device which may not be fully accessed initially. A planar key pair is established which identifies a planar board included within the system. The planar key pair includes a planar public key and a planar private key. The particular device is associated with the planar by storing the device public key only within the planar, and by storing the planar public key only within the device. Access to the data stored within the device is limited to only a planar which has the stored device public key.
