Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The embodiment of the present invention provides a method for protecting data, see figure 1 , including:

[0023] 11: Extract the environment information of the equipment in the security environment (referred to as the security environment information for short), and acquire the environment factor according to the security environment information.

[0024] The above devices are the devices where the data to be protected resides.

[0025] 12: Encrypt the sensitive data in the device by using the security environment factor, and destroy the environment factor after confirming that the encryption is successful.

[0026] The above-mentioned security environment can be the working environment when the equipment is installed for the...

Abstract

The invention discloses a method and a system for protecting data. The method for protecting the data, which is provided by the embodiment of the invention, comprises the steps that in primary initialization process of equipment where data are located, environmental factors are obtained according to the environmental information of the equipment in a security environment; sensitive data in the equipment are encrypted by utilizing the environmental factors in the security environment, and after the encryption determinately succeeds, the environmental factors are destroyed; each time the equipment is started, environmental factors are obtained according to the environmental information of the equipment in the current environment, then the encrypted sensitive data in the equipment are decrypted by utilizing the environmental factors in the current environment; and if the decryption succeeds, the access of the data in the equipment is allowed, and if the decryption fails, the access of the data in the equipment is denied. The hardware cost needed by the scheme is low, and the risk of data leakage can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method and system for protecting data. Background technique [0002] With the popularization of information carrier equipment, more and more automatic control and information processing systems adopt embedded architecture, and social organizations such as individuals and enterprises rely more and more on information carrier equipment. Embedded devices are a commonly used information carrier device. The popularity of embedded devices improves social production efficiency and facilitates production control on the one hand. On the other hand, it also raises security protection requirements for various information records in the system. specific requirements. [0003] In recent years, the research and development of many information security vendors on data protection technology is mainly limited to how to protect the data security of embedded devices in the network, such as...
