Abstract:
A cryptographic ASIC and method for autonomously storing data into a one-time programmable memory in isolation. Internal circuitry provides programming pulses of a given voltage magnitude and duration for changing the state of selected memory elements. Use of internal circuitry reduces pin count and increases reliability and security over devices relying on external circuitry to provide programming pulses. In one embodiment, the stored data comprises cryptographic data for enforcing a derivative key hierarchy for managing an information stream, such as a blockchain.

Claim (Index 32):
A system for managing operations on a blockchain information stream, the system comprising:\n means for deriving a transform key from a temporary copy of a user passphrase; means for storing the transform key in a one-time programmable memory in isolation using programming pulses from internal circuitry; means for processing an input message from the blockchain information stream by:\n hashing the input message to obtain an input message hash; \n performing a customized transforming of the input message hash using the transform key, to obtain a transformed hash; and \n hashing the transformed hash into an output result; and \n means for creating the blockchain information stream with the output result based on the user passphrase.
