Estimating the term…
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.
A cryptographic security token comprising:
A cryptographic security token according to claim [0018], further comprising:
A cryptographic security token according to claim [0019], wherein said conformal layer has properties that block probing using X-rays, focused electron and ion beam scanning and scanning electron microscopy.
A cryptographic security token according to claim[0018], further comprising:
A cryptographic security token according to claim [0019], wherein said compound comprises one or more of metals, heavy metals, graphone, carbon, carbon fullerene structures, synthetic diamond dust and quantum dots.
A cryptographic security token according to claim [0019], wherein said anti-tamper film comprises an active or passive anti-tamper mesh film.
A cryptographic security token according to claim [0019], wherein said compound comprises one or more shielding components selected from the group of ground metal compounds, graphene, carbon nanotubes, synthetic diamond and quantum dots.
A cryptographic security token according to claim [0019], further comprising:
A cryptographic security token according to claim [0019] further comprising a waterproof synthetic printing medium over said UV cured adhesive material, wherein polyolefin hydrophilic properties of the waterproof synthetic printing medium are custom infused with micro-taggants that fluoresce or leach die when probed.
A cryptographic security token according to claim [0021], wherein said voltage glitch detector comprises a comparator connected to a power bus in said cryptographic security token and to a reference voltage.
