Embodiment Construction

[0040] 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 with reference to the accompanying drawings and examples.

[0041] In order to improve the security of reading the data stored in the memory, the memory in the system provided by the present invention stores data in plain text, and when the data in plain text is to be provided to a legitimate user, the decoded random number seed received from the main chip is processed. Decode and calculate the pseudo-random number, and then encrypt the stored data plaintext to obtain the ciphertext and transmit it to the main chip; after the main chip in the system provided by the present invention receives the ciphertext, use the random number seed to calculate the pseudo-random number, Decrypt the received ciphertext to obtain the data plaintext.

[0042] Since the system and method provided by the present invention use the m...

Abstract

The invention discloses a system and a method for ensuring the safe read of data stored in a storage. The system comprises a storage and a main chip, wherein the main chip is used for generating random number seeds and sending to the storage after the random number seeds are coded; generated random numbers are stirred to obtain pseudo random numbers by adopting the generated random number seeds, and an encrypted data clear text received from the storage is decrypted to obtain the data clear text; the storage is used for decoding the coded random number seeds received from the main chip to obtain the random number seeds, the generated random number seeds are stirred to obtain the pseudo random numbers, and the stored data clear text is encrypted by adopting the pseudo random numbers and then sent to the main chip. The system and the method enhance the read safety of the data stored in the storage.

Description

technical field [0001] The invention relates to data security technology, in particular to a system and method for ensuring safe reading of data stored in a memory. Background technique [0002] Some data that needs to be kept secret, such as the disclosure of restricted information or confidential information, is a security threat in modern society. Whether it is an enterprise or an individual user, higher data security is required. [0003] Data confidentiality is an important aspect of Internet technology (IT, Internet Technology) information security. How to ensure data security and prevent it from being stolen is generally realized by encryption. That is to say, according to the set encryption method, for example, the key reorganizes the plaintext of the data to obtain the ciphertext, so that the illegal obtainer cannot obtain the corresponding plaintext of the data according to the obtained ciphertext. It can be seen that the encryption method can make some important...
