Application: Homomorphic encryption using smart contracts (Patent ID: US20230421351A1)
The patent filed by NEC Corp. describes a system of cryptography for securing data on a blockchain using homomorphic encryption. The system involves obtaining encrypted data items, processing them computationally with homomorphic encryption mechanisms, and posting the encrypted outcomes on the blockchain via smart contracts. The encrypted outcomes are decrypted using private keys corresponding to the public keys used for encryption.
Additionally, the system allows for offloading computational processes to network-connected servers, generating private and public key pairs compliant with homomorphic encryption, aggregating outcomes from multiple offloading smart contracts, obtaining zero knowledge proofs, and interacting with client terminals to encrypt and decrypt data. The method and non-transitory medium storing program instructions also detail the process of obtaining, processing, and posting encrypted data on the blockchain while ensuring compliance with homomorphic encryption mechanisms. Overall, the system aims to enhance data security on the blockchain through the use of advanced cryptographic techniques.
