Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] Such as figure 1 As shown, an embedded encryption system includes an embedded terminal and a server or a mobile terminal, and the two communicate through WIFI or Bluetooth.

[0051] Embedded terminal includes MCU, FLASH storage unit, encryption chip. The MCU is the main control unit, which is connected with the FLASH storage unit and the encryption chip to transmit data and command information; the FLASH storage unit is used to store valid information that needs to be saved, and is controlled by the MCU. The encryption chip is responsible for the encryption operation, and the encryption method is selected through the control of the MCU.

[0052] The server or mobile terminal communicates with the embedded terminal to realize the verification of encrypted information between the two to ensure the security of the system.

[0053] Such as figur...

Abstract

The invention discloses a software and hardware combination embedded terminal encryption system and an encryption method. The software and hardware combination embedded terminal encryption system comprises an embedded terminal communicating with a server or a mobile terminal, wherein the embedded terminal comprises an MCU; the MCU is connected with a FLASH storage unit and an encryption chip respectively and is used for transmitting data and command information; the FLASH storage unit is controlled by the MCU; the encryption chip is used for encryption operation and can select an encryption mode according to a control instruction of the MCU; when working, the embedded terminal firstly passes through hardware startup encryption verification, then passes through wireless communication encryption verification and finally operates normally; by the combination of hardware startup encryption and wireless communication encryption, encryption of the embedded terminal is realized; due to dual encryption and dual insurance, security and reliability of operation of the embedded terminal are guaranteed; meanwhile, competitors maliciously crack hardware equipment and embedded programs thereof are also effectively prevented; and non-disclosure of a technology is effectively guaranteed.

Description

technical field [0001] The invention relates to an encryption method, in particular to an embedded terminal encryption system and encryption method combining software and hardware. Background technique [0002] At present, the research and development cost of hardware products is very high, and the research on its stability and reliability is even more time-consuming and laborious. Some competitors, in order to save effort, will crack hardware products in the same industry, which often causes great damage to manufacturers. Loss, in response to this imagination, many manufacturers have adopted encrypted counting to prevent the product from being cracked. [0003] At present, manufacturers of large logarithms use software encryption methods. The main methods are to use software methods to hide or cover up part of the program codes used in the product, and use obfuscation methods to confuse part of the program codes and data. Use the method of jumping randomly to make the prog...
