Abstract: A method for providing location based security for communication between a remote device and a mobile device having a global positioning system receiver for determining its current position. The method comprises receiving geographic data from the remote device, determining if the mobile device is within a predetermined geographic region based on the geographic data and the current position, and enabling subsequent communication with the remote device when the current position is within the predetermined geographic region.

Abstract: Methods and apparatus are provided for protecting private data on a vehicle. The method comprises receiving a first signal generated by a user of the vehicle and, in response to the first signal, deleting predetermined data stored on the vehicle to prevent the private data from being accessed.

Abstract: Methods and apparatus are provided for establishing a secure connection with a mobile device that is configured to store a first private key that mathematically corresponds to a first public key. The method comprises receiving a quasi-public key from a trusted entity, wherein the quasi-public key mathematically corresponds to a quasi-private key that is stored on the mobile device, receiving a first digital certificate from the mobile device, the first digital certificate comprising the first public key and a first digital signature generated with the quasi-private key, and authenticating the first digital certificate using the first digital signature and the quasi-public key.

Abstract: Methods and systems are provided for verifying that a remote device is a trusted entity. The method comprises receiving a first digital certificate from a first certificate authority, wherein the first certificate authority is a trusted entity, receiving a second digital certificate from the remote device during a first handshake procedure for establishing a secure connection, the second digital certificate corresponding to a second certificate authority, determining if the second digital certificate was issued by the first certificate authority based on at least a portion of the contents of the first digital certificate, and storing the second digital certificate to enable subsequent authentication of additional digital certificates received from the remote device, if the second digital certificate was issued by the first certificate authority.
