Quantum-lattice BlockChain Structure

  • Index
  • Timestamp
  • Data
  • Quantum Key
  • hash (lattice-based)

Quantum Key Distribution ( based on BB92 protocol)

  • Simulate BBM92 quantum key distribution protocol
  • Creation of two quantum circuits named Alice and Bob
  • Apply Hadamard gate on Alice's qubit, measure it, and share the circuit state with Bob
  • Simulate circuits, compare results, and establish a secure key

Latice Based Hash

  • Take index, previous_hash, timestamp, data, quantum_key as input
  • Calculate hash using lattice-based hash function
  • lattice-based hash function employs SHAKE-256 algorithm and large prime modulus for message digest and producing lattice-based hash using previous_hash
