Security encryption method, encryption machine and terminal device

Abstract

The present invention is applicable to the technical field of information security, and provides a security encryption method, an encryption machine, and a terminal device. The security encryption method is applied to the encryption machine, and the encryption machine comprises a security processor CPU, a sensor, a battery backup area BBL Area, and a rigger circuit. The security encryption methodcomprises an encryption machine firmware security detection method. The encryption machine firmware security detection method comprises: detecting the internal and external condition of the security processor CPU by using the sensor; if the abnormality is detected, issuing an early warning signal; and directly notifying or through the trigger circuit, notifying the BBL Area of the early warning signal so as to destroy the content of the backup area. The security encryption method further comprises: a software secure startup method and a key secure storage method. According to the technical scheme of the present invention, low-cost hardware and structure design is realized, and the machine purchase cost is saved; and a hierarchical software model is provided, a secure startup control mode is provided, and full-cycle key security management is realized.

Description

Technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a security encryption method, encryption machine and terminal equipment. Background technique [0002] With the continuous development of information technology and the prevalence of the Internet, more and more data needs to be transmitted on the network, including interactive information, emails, identity information, transaction information, and business data. However, at present, illegal activities such as illegal monitoring, stealing, and tampering of data are increasing, so the security of data is getting more and more attention. [0003] The use of cryptographic algorithms to encrypt data before transmission is an effective means to ensure data security and data integrity. Therefore, many IT manufacturers have developed many encryption devices or encryption software. The encryption device or software generates encryption keys to achieve Encrypt plaintext ...
