The invention introduces a method for programming and recovering protected data. Protected data instructed by a data write command is received from a host side in multiple batches. After an encoding algorithm is used to generate an intermediate calculation result according to a first portion of the protected data, and an authentication key, multiple authentication calculation operations for remaining portions of the protected data, and multiple data programming operations for all portions of the protected data are arranged to enable the authentication calculation operations to be performed in parallel to the data programming operations. Each data programming operation is performed to program a corresponding portion of the protected data and a metadata associated with the corresponding portion of the protected data into a current block of a flash module. The metadata comprises information about whether the protected data has passed an authentication.
