Abstract

The invention discloses an encrypted storage method and an encrypted storage card based on a quantum key, and the encrypted storage method based on the quantum key comprises the steps: carrying out the identity authentication of an encrypted storage visitor; receiving to-be-stored data sent by the visitor passing the identity authentication; adopting a preset encryption algorithm and a session keyto perform encryption, wherein the session key is generated by a quantum random number, encrypted by using an equipment key or a key encryption key and then stored in a hidden storage area, the equipment key or the key encryption key is encrypted by a main key, and the main key is generated by the quantum key generated by the quantum random number and is periodically replaced; and storing the encrypted to-be-stored data in the encrypted storage area. According to the encrypted storage method based on the quantum key and the encrypted storage card disclosed by the invention, the safety of datastorage of the storage equipment is improved.
