Encrypted storage method based on quantum key and encrypted storage card

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.

Description

technical field [0001] The embodiments of the present invention relate to storage technologies, and in particular to a quantum key-based encrypted storage method and encrypted storage card. Background technique [0002] With the advent of the era of big data and the popularization of smart mobile terminals, the data security of mobile terminals is becoming more and more important, but there is a lack of effective methods and measures for the secure storage of mobile terminal data. [0003] Most of the current mobile terminals have a card slot for an external memory card, and the storage space of the mobile terminal can be expanded through the external memory card. The external memory card can encrypt and protect stored data through encryption measures, and commonly used encrypted memory cards include encrypted SD cards, for example. Because the encrypted SD card is small in size, easy to carry, and does not need to change the hardware structure of the mobile terminal, it ha...

Problems solved by technology

However, the random number generator of the current encryption memory card is a hardware random number generator based on electronic noise or a built-in software random number generator

Hardware random number generators based on electronic noise generate random numbers at a low rate, and the source of true randomness is unclear, while software random number generators are essentially pseudo-random numbers, and the random number generation rate is also low

Therefore, the encryption key of the current encryption memory card has a high risk of being cracked
