Problems solved by technology

[0004] However, because it usually takes a certain amount of time to collect identity information for applications that access encrypted data, it also brings certain difficulties to hardware implementation, which in turn leads to judging whether to perform data encryption and decryption operations based on the collected identity information. Increases the time required for data encryption and decryption as well as the implementation cost

Embodiment Construction

[0044] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0045] The access management method and system for storing data provided by the embodiments of the present invention can be used in intelligent security chips. A double matching of the access address and the identity information is requested, and after the double matching is successful, data access is performed on the storage module of the chip according to the storage access request.

Abstract

The invention relates to an access management method and system for storage data. The method comprises the steps that an access storage request is received, wherein the access storage request includes an access address and identity information; whether a storage unit which matches the access address exists is determined; if a storage unit which matches the access address exists, whether the identity information has the access right of the storage unit is determined; and if the identity information has the access right of the storage unit, data access is carried out on the storage unit according to the access storage request. According to the embodiment of the invention, a storage module does not need to take the initiative to collect the identity of a data access side, which reduces the hardware implementation cost and improves the efficiency of data access; whether the data access side can carry out data access is determined by double matching the storage unit and the access right; and the safety of the storage data can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to an access management method and system for storing data. Background technique [0002] As information security is paid more and more attention by people, the encryption and decryption transmission of various application data in terminal equipment has become an important means to ensure information security. Encryption and decryption transmission refers to the use of encryption and decryption devices to encrypt the data of different application categories at the chip sending end in the terminal equipment, and send the encrypted data to the chip receiving end, and the chip receiving end uses the encryption and decryption device to decrypt the received encrypted data. The restored application data is obtained, and the restored application data is stored in the memory module of the chip for reading and consumption by the relevant application consumption module. In order to pre...
