  • Patent number: 10552645
    Abstract: 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.
    Type: Grant
