A secure element access interface protocol adaptation method and device

Abstract

The present application provides a secure element access interface protocol adaptation method and device, wherein the method includes: responding to a received secure element access request, obtaining version information of the target operating system, and determining the first default supported version of the target operating system according to the version information. An interface protocol; based on the target operating system, the preset interface protocol corresponding to the first interface protocol is tested through a reflection mechanism, and the second interface protocol actually supported by the target operating system is determined according to the test feedback results; through the second interface protocol and the target The operating system establishes the connection. Through the adaptation method provided by this application, developers can focus on the development of application services without caring about the version difference and interface difference of the target device, which solves the cumbersome technology of secure element access interface protocol adaptation caused by the existing technology problems and effectively improve the efficiency of application development.

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...
