Quantum resistant blockchain with multi-dimensional quantum key distribution

摘要

A system for generating a blockchain comprises first circuitry for receiving a first group of data. Blockchain processing circuitry generates a blockchain for a plurality of groups of data. The blockchain processing circuitry generates the blockchain by generating a first nonce for a first block of the blockchain. The blockchain processing circuitry performs a first hash using the first group of data and the first nonce as an input to a hash function to generate a first digital signature for the first block as an output. The hash function uses encryption based on quantum key distribution using N-state qudits where N is greater than 2. The block chain processing circuitry receives a second group of data and generates a second nonce for a second block of the blockchain. A second hash is performed using the second group of data, the second nonce and the first digital signature to generate a second digital signature for the second block as an output. The hash function uses encryption based on the quantum key distribution using N-state qudits where N is greater than 2.
