Abstract

The invention discloses a data encryption system, method and apparatus and belongs to the field of encryption technology. The data encryption system comprises a burner, a single-chip microcontroller (SCM) and a server. The burner generates a first public key and a first private key by using a predetermined generating algorithm. The server generates a second public key and a second private key by using the predetermined generating algorithm. The burner acquires the second public key, performs key negotiation according to the first private key and the second public key, and programs an obtained shared key and the first public key to the SCM. The SCM encrypts the plaintext data with the shared key, and sends an obtained cryptograph and the first public key to the server. The server performs key negotiation according to the first public key and the second private key, and decrypts the cryptograph by using the obtained shared key. The data encryption system, method and apparatus solve a problem that the storage capacity of the server is highly required when the number of the SCMs is very large, and achieve an effect of greatly reducing the requirement for the storage capacity of the server while ensuring the security of the data.

Description

technical field [0001] The present invention relates to the technical field of encryption, in particular to a data encryption system, method and device. Background technique [0002] In order to ensure the security of the data in the single-chip microcomputer, it is usually necessary to encrypt the data to be sent by the single-chip microcomputer. [0003] Because the computing power of the single-chip microcomputer itself is very poor, it generally does not have the ability to generate keys. When encrypting the data in the single-chip microcomputer, it needs to be combined with the burner to realize data encryption. [0004] The commonly used encryption method in single-chip microcomputer is: the burner generates a key, burns the generated key into the single-chip microcomputer, the single-chip microcomputer sends the obtained key to the server, and the server stores the key corresponding to the single-chip microcomputer; the single-chip microcomputer needs to send the key ...
