Abstract
Methods and systems are provided that provide a portable, cryptographic hardware-software device allowing balancing of the needed heightened security while maintaining the modified communication device's original features and value. The system comprises a single chip comprising a self-contained security boundary and cryptographic processing, and is enabled to quickly and easily connect to and modify an existing, commercial, off the shelf mobile communication device. The systems may be enabled to modify the existing device by being contained in hardware, for example the battery of a smart phone. Then, the system may be connected to the existing device's interface, for example via a “micro-USB” or other suitable connection, and subsequently provide cryptographic functionality to the existing device.
