Abstract
The invention relates to a method, a non-transitory computer program product, and an apparatus for encrypting and decrypting physical-address information. The method includes: receiving a first read command requesting of the flash controller for first physical block addresses (PBAs) corresponding to a logical block address (LBA) range from a host side, wherein each first PBA indicates which physical address that user data of a first LBA of the LBA range is physically stored in a flash device; reading the first PBAs corresponding to the LBA range from the flash device; arranging the first PBAs into entries; encrypting content of each entry by using an encryption algorithm with an encryption parameter to obtain an encrypted entry; and delivering the encrypted entries to the host side.
