Abstract: Apparatus, method, computer program product and computer readable medium are disclosed for trusted computing. A method includes, at an isolated processor including a trusted execution environment and an isolated storage, receiving data encrypted with a first public key; decrypting the encrypted data with a first private key; performing calculation on the decrypted data by using an approved program; and providing the calculation result, wherein the approved program is authorized by a smart contract, a unique identifier of the smart contract is stored in the isolated processor, both the approved program and the isolated processor are verified by at least one participant of the smart contract, and the first public key and the first private key are generated by the isolated processor.
