In order to reduce the computational overhead of proof of retrievability（POR） scheme, a new POR scheme based on low-density parity-check（LDPC） codes is proposed, noted as LDPC-POR. In the model of PORs scheme, the client preprocesses the data and sends it to an untrusted server for storage, only keeping some metadata.
