Full Cycle Data Protection Scheme of Power Parameters in Smart Grid Based on Integer Fully Homomorphic Encryption

Power parameter data protection is an important guarantee for the smooth operation of smart grid. In order to realize the full life cycle data protection of power parameters based on lattice cipher and DALCM model, this paper proposes a full life cycle data protection scheme for power parameters generated by smart terminals in power grids. The scheme in electricity parameter data phase, the electricity parameter for data encryption, the encrypted cryptograph no longer decrypt data in data processing stage, ciphertext survival to data disposal, scheme proposed can provide data security support for the operation of the smart grid, from the perspective of data security to ensure the smooth operation of the smart grid.
