US Patent 9059980 Systems and methods for authenticating mobile devices

Embodiments of the invention provide systems and methods for authenticating mobile devices. Device identifying information may be received for a mobile device. A base level key may also be communicated to the mobile device. The base level key may be utilized by the mobile device to derive unique transaction specific keys to encrypt subsequent communications output by the mobile device. A communication encrypted with a unique transaction specific key may be received from the mobile device. Based at least in part upon the device identifying information and the base level key, a derived key may be generated, and the derived key may be utilized to decrypt the received communication and authenticate the mobile device. In certain embodiments, the above operations may be performed by one or more computers associated with a service provider.
