Abstract

The invention provides a data encryption method and device, a data decryption method and device and a storage device, and the method comprises the steps: generating an encryption password according to an initial random number and an encryption algorithm stored in a hidden region before target data is stored in a protection region, wherein the protection region and the hidden region are two regions arranged in the storage device, the protection region is used for storing encrypted target data and an installation package corresponding to a decryption application program, the protection region is a read-only storage region, the hidden region is used for storing an initial random number and address information of the target data, a decryption algorithm corresponding to the installation package is the same as an encryption algorithm, and then the encryption password is used for encrypting the target data. Therefore, the target data stored in the protection region hidden of the storage device can be protected from being read by the unauthorized reading device, the encryption password is not easy to crack, and the encryption performance is good.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a data encryption method, a decryption method and device, and a storage device. Background technique [0002] In recent years, blockchain, Internet of Things, smart cities and new financial technology services have become the main force in the development of emerging applications, and there are increasingly stringent requirements for data confidentiality and information security. In various secure digital card (Secure Digital Card, SD) applications, in order to ensure the confidentiality, integrity and availability of the data stored in the SD card, the SD card is generally encrypted and decrypted through information security encryption technology , in order to achieve the security of information application and transmission. For example, in order to prevent data such as music or movies stored in the SD card from being copied without authorization, the data st...
