Integrated processor chip, application program terminal and terminal equipment

Abstract

The invention discloses an integrated processor chip, an application program terminal and terminal equipment. The integrated processor chip comprises a Flash storage area; the Flash storage area is internally provided with a safety area which is used for storing a safety instruction and only allows an access request with a safety attribute to access; and the safety area performs security information interaction with the application software end through a hidden SE interface arranged in a lib library file of the application software end. The processor chip does not need to be additionally provided with a safety chip, and only a universal single-chip microcomputer provided with an iSE mechanism needs to be selected. The intermediate interaction process is completed between the lib and the SE, and the security is high.

Description

technical field [0001] The invention relates to the technical field of processors, in particular to an integrated processor chip, an application program terminal and terminal equipment. Background technique [0002] Information security has gradually become a basic requirement of modern electronic products, ranging from common single-chip products, such as the protection of software copyrights and application data; to complex systems, such as identifying the identity and Permissions, as well as ensuring data security during communication, are inseparable from information security. In view of the information security requirements in various scenarios, the current technology mainly proposes various solutions from the perspective of hardware protection and software encryption and decryption, which are divided into the following two categories according to whether there are standards: [0003] [1] For electronic products under industry standards (or de facto standards), each li...

Problems solved by technology

[0004] [2] Electronic products without safety standards: If the main controller has security functions, it can directly use its security functions to provide protection; if the main control has low security performance or has been cracked, it is necessary to add an independent security chip to provide Assure

[0012] [1] An independent processor is required to perform calculations, which increases the cost, especially for low-end products;

[0013] [2] The product is independent and needs to occupy a certain amount of space. It is not suitable for products with small appearance and size requirements;

[0014] [3] There are certain technical barriers to use: if you use standard SE, users need to be familiar with the specification; if you use custom, users need to design their own security mechanisms and develop related software; both types have technical requirements for developers , will increase the product development cycle;
