Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] figure 1 , figure 2 Shown is the implementation method of the memory data encryption protection realized by the present invention, as shown in the figure. The memory first needs to open up a user configuration area and configure random seeds.

[0025] S101. Realize the random sequence module, using the shift register sequence (m sequence), for example, select the m sequence primitive polynomial x^24+x^7+x^2+x+1.

[0026] S102. Design a random seed for the user configuration area. Set the random seed to 32 bits, and the encryption effect is higher. At the same time, the random seed need...

Abstract

The invention discloses a method for realizing encryption and protection of memory data. In the method, the memory first needs to open up a user configuration area, configure a random seed, and set a random sequence module, and then process the original data through the random sequence module, so that the original data is saved in the The address of the memory becomes a random address; the original data will be processed by the random sequence module, so that the original data becomes random data. The invention realizes the purpose of highly encrypted protection of memory data, improves the security of user data, and improves the reliability of chips, and at the same time, the scheme is simple and convenient to implement, and the area power consumption is small.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a chip data storage method. Background technique [0002] In chip applications, chip memory data generally integrates customer applications or stores user data. These data may involve issues such as privacy and security, especially in industries such as finance, communications, and social security. Therefore, the security of memory data Sex must be guaranteed. Data security must be ensured not only in normal application environments, but also in the event of malicious attacks, so that crackers cannot obtain user privacy data and customer applications, resulting in the risk of information leakage. [0003] Patent application 200910081928.6 discloses a system and method for ensuring safe reading of data stored in a memory, including a memory and a main chip, wherein the main chip is used to generate a random number seed, which is decoded and sent to the memory; T...
