AI Technical Summary

Technical Problem

Existing solid-state drives have insufficient security in data encryption, and usually use the same simple password to protect large amounts of data, resulting in poor data security.

Method used

Multiple keys are used to encrypt multiple data, and the data encryption key is protected through the complex key generated by the key management platform, and multiple key transformation information are used between the client and the key management platform to generate multiple The second key encrypts and decrypts the data encryption key respectively.

Benefits of technology

Improve data security, reduce the amount of data interaction between the key management platform and the client, and enhance the protection of keys and data.

Abstract

The invention discloses a data encryption read-write method and device for a solid state disk and electronic equipment, and the method comprises the steps: the solid state disk stores encrypted data, K pieces of encrypted data are encrypted by adopting K data encryption keys, the K data encryption keys are encrypted by adopting K second keys, and the K second keys are generated according to a first key and key transformation information, the method comprises the following steps: a client obtains a data use request for K encrypted data of the solid state disk and uploads the data use request; the key management platform sends key related information to the client according to the data use request, and the key related information comprises a first key of the solid state disk. According to the invention, the first secret key stored in the secret key management platform and the secret key transformation information stored in the client are utilized to generate a plurality of second secret keys to carry out encryption protection on different data encryption secret keys, so that the data security is improved, and the data volume of interaction between the secret key management platform and the client is reduced.
