Embodiment Construction

[0038] The embodiment of the present application provides a hardware access interface protocol adaptation method and device, which are used to solve the technical problem of complicated adaptation of the existing security element access interface protocol.

[0039] see figure 1 , the current computer technology is developing rapidly, the update cycle of the operating system version is getting shorter and shorter, and with the update of the operating system, the interactive interface protocol between the application program and the secure element is also constantly updated. For developers, the usual practice is to develop in conjunction with the current mainstream interface protocols. However, the operating systems of various terminals equipped with secure elements on the market are not necessarily the latest versions, and due to differences in terminal uses, , the interface protocols it supports may also be different, especially for open source systems like Linux or Android, w...

Abstract

The invention provides a secure element access interface protocol adaptation method and device, and the method comprises the steps: obtaining the version information of a target operating system in response to a received secure element access request, and determining a first interface protocol defaulted and supported by the target operating system according to the version information; based on thetarget operating system, testing a preset interface protocol corresponding to the first interface protocol through a reflection mechanism, and determining a second interface protocol actually supported by the target operating system according to a test feedback result; and establishing connection with the target operating system through the second interface protocol. Through the adaptation methodprovided by the invention, developers do not need to care about the problems of version difference, interface difference and the like of the target equipment and focus on the development of the application service, so that the technical problem of tedious adaptation of the security element access interface protocol in the prior art is solved, and the application development efficiency is effectively improved.

Description

technical field [0001] The present application relates to the field of communication interface protocols, in particular to a secure element access interface protocol adaptation method and device. Background technique [0002] Secure Element (Secure Element), referred to as SE, is a hardware device used to prevent external malicious analysis attacks and protect data security. It is usually provided in the form of a chip with encryption / decryption logic circuits, such as SIM cards and SD cards commonly used in daily life. All cards are secure elements. When an application program accesses a secure element, it needs to rely on the operating system to establish an access connection with the secure element through a specific interface protocol. [0003] However, with the update of the operating system version and interface protocol, and the difficulty of completely unifying the operating system version and interface protocol of existing terminals on the market, the interface prot...
