Abstract

The disclosure provides for one or more devices and associated system that securitize and conceal data transmitted to and/or data received from the devices that utilize one or more master keys comprising at least one device that conceals and reveals such that the data and/or associated data files utilize both master keys and one or more key selectors, wherein the master keys and key selectors produce a specific set of one or more keys that conceal the data and/or associated data files such that one or more key selectors coincide with at least one value that directly corresponds with created cipher data and/or cipher data files. The key selectors can also be concealed and revealed as required. Produced concealed data and concealed data files can only be concealed and revealed with one or more master keys and one or more key selectors.

How It Works

A step-by-step walkthrough. It plays on its own, or click the dots and arrows to move through it yourself.

US 10,616,192 B2

A different key for every block of data

Two secrets needed: a master key you already hold, plus a per-block token
SENDER RECEIVER master key same master key master key never moves selector random, per block DSES a different key per block token only the token rides with the ciphertext token points to the exact block
1 / 5

Picture a vault where the combination changes for every drawer, and the lock needs two things: a master ring you already own (never mailed to anyone) and a little scratch-off ticket taped to each package. The ticket alone is useless and the ring alone is useless, but the lock fuses them on the spot to compute that drawer's exact combination. The ticket even doubles as the drawer number, so you walk straight to the right block instead of opening every one in order. Steal a package in transit and all you get is a ticket.

  • Master key held at both ends, never transmitted
  • Random key selector makes every block's key random
  • Dynamically selectable encryption system rebuilds a key per block
  • Token rides with the ciphertext and doubles as a block address
