Abstract:
A system and method for creating a trusted workspace on a commercial mobile device using a cryptographic security token having a secure microprocessor, a secure bus connected to said secure microprocessor, a bus isolation microcontroller connected to said secure bus wherein said bus isolation microcontroller comprises firmware for controlling communications through said secure bus to said secure microprocessor, a first NFC antenna connected to said bus isolation microcontroller, and a second NFC antenna connected to said secure microprocessor. The secure microprocessor and said bus isolation microprocessor are powered by energy received through said first NFC antenna and said second NFC antenna. The cryptographic security token receives data from outside said cryptographic security token only through said first NFC antenna. The token or module may further have a bi-state or bi-stable display and a secure memory, each connected to the secure microprocessor by a secure bus.

Claim (Index 1):
A method for creating a trusted workspace on a mobile device using a cryptographic security token comprising a secure microprocessor, a secure bus connected to said secure microprocessor, a bus isolation microcontroller connected to said secure bus, said bus isolation microcontroller comprising firmware for controlling communications through said secure bus to said secure microprocessor, a first NFC antenna connected to said bus isolation microcontroller, and a second NFC antenna connected to said secure microprocessor, wherein said secure microprocessor and said bus isolation microprocessor are powered by energy received through said first NFC antenna and said second NFC antenna, and wherein said cryptographic security token receives data from outside said cryptographic security token only through said first NFC antenna, the method comprising the steps of:\n provisioning the cryptographic module and the mobile device, wherein the provisioning comprises:\n registering a user in the cryptographic module to establish the user's identity; \n creating authentication certificates associated with said user; \n loading private keys on to the cryptographic module and the mobile device; \n creating a first user password to enable access to a basic system on said mobile device and storing the first user password in the cryptographic module; \n creating a random password and loading said random password into a register on the cryptographic module, the random password only being accessible to the user through a secure display on the cryptographic module; and \n storing a low-level bootloader in the cryptographic module; \n initializing and booting up the cryptographic module and the mobile device; and transitioning the cryptographic module and the mobile device into the trusted work space.
