Problems solved by technology

[0002] Trusty TEE is a set of software components that support Trusted Execution Environment (TEE) on mobile devices. TrustyTEE Attestation key (trusted TEE authentication key) is an important module for Google CTS / GTS detection. Currently, PCs provided by chip solution providers The board programming tool cannot retroactively detect whether the Android product has been correctly written to the Attestationkey (and Google has not provided any related detection methods or interfaces). It will lead to the failure of Google related certification, and it will also lead to product rework and increase production costs

Abstract

The invention relates to a TEE authentication key detection method and a system. The method comprises the following steps: receiving a TEE authentication key detection request; detecting an EC key anddetecting an RSA key; if the detection of the EC key succeeds and the detection of the RSA key succeeds, prompting that the key detection key is successful; otherwise, prompting that the key detection fails. The TEE authentication key detection method and system of the present invention are applied to the mass production of Android product. When the TEE authentication key detection method and system are applied to the mass production of Android products, factory production line is provided with Trusty TEE Attestation Key (TTEE Authentication Key) detection to improve production line efficiency and product yield, to ensure that Google certification test is passed smoothly.

Description

technical field [0001] The present invention relates to the field of Trusty TEE, and more specifically, relates to a TEE authentication key detection method and system. Background technique [0002] Trusty TEE is a set of software components that support Trusted Execution Environment (TEE) on mobile devices. TrustyTEE Attestation key (trusted TEE authentication key) is an important module for Google CTS / GTS detection. Currently, PCs provided by chip solution providers The board programming tool cannot retroactively detect whether the Android product has been correctly written to the Attestationkey (and Google has not provided any related detection methods or interfaces). It will lead to the failure of Google related certification, and it will also lead to product rework and increase production costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a TEE authentication key detection method...
