Embodiments of the invention can provide systems and methods for encrypting mobile device communications. According to one example embodiment of the invention, a method for encrypting mobile device communications is provided. The method can include generating, by a first application stored on a first memory of a mobile device, a message to be communicated to an intended recipient; providing, by the first application to an authentication application stored on a second memory of the mobile device, the message; encrypting, by the authentication application, the message; providing, by the authentication application to the first application, the encrypted message; and directing, by the first application, communication of the message to the intended recipient.

Systems and methods for encrypting mobile device communications

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.

Systems and methods for authenticating mobile devices

Embodiments of the invention provide systems and methods for authenticating mobile devices. A registration request and identifying information for a mobile device or a secure element associated with the mobile device may be received. Based upon the received identifying information and a base level key, a rotated key for the mobile device may be determined. The determined rotated key may then be provided to the mobile device, and the rotated key may be utilized for subsequent authentication of the mobile device.
