Universal TA (trusted application) payment platform and payment method

Abstract

The invention discloses a universal TA (trusted application) payment platform and payment method, relates to the technical field of mobile payment, and solves the technical problems of high development difficulty and development cost of a TA in the prior art. The universal TA payment platform comprises a communication module, a storage module and a secure user interaction module, the communication module is used for communicating with the TA, a data and instruction transmitting channel is built between the TA and the universal TA payment platform, a standard interface provided by a TEE OS (trusted execution environment operation system) based on standard GP (general purpose) TEE specifications is packaged in the storage module, the storage module is used for providing a plurality of secure storage spaces, different secure storage spaces are used for packaging different TEE OS files and object operations, a standard interface provided by the TEE OS based on the standard GP TEE specifications is packaged in the secure user interaction module, and the secure user interaction module is used for interacting between the TA and a user. The universal TA payment platform is used for mobile payment.

Description

technical field [0001] The invention relates to the technical field of mobile payment, in particular to a general TA payment platform and payment method. Background technique [0002] At present, Trusted Execution Environment (TEE) and Trusted Application (TA) have begun to be applied in the field of mobile payment technology to provide more security reinforcement measures for mobile payment to ensure the safety of users' property. Among them, TEE manufacturers have developed their own unique TEE operating systems (TEE OS) in accordance with the GP TEE specification. The above-mentioned TEE OS is usually implemented based on Qualcomm, MTK or self-developed chips. [0003] However, in the prior art, the following problems exist in the application process of TEE OS and TA: [0004] On the one hand, the development and deployment of TA are closely related to TEE OS, so that TA developed and deployed based on a certain TEE OS cannot be directly used under other TEE OS, so TA de...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the development and deployment of TA are closely related to TEE OS, so that TA developed and deployed based on a certain TEE OS cannot be directly used under other TEE OS, so TA developers must develop separately for different TEE OS. TA increases the difficulty of TA development and is not conducive to the transplantation of TA

[0005] On the other hand, even if multiple TAs are developed under the same TEE OS, each TA needs to be developed independently because of the different business processes of each TA, resulting in low code reusability and high development costs
