Problems solved by technology

[0005] Among the current signature schemes mentioned above, the Android native scheme does not perform CA certification on the application certificate. The existing CA certification scheme is to preset the CA certificate into the device before the device leaves the factory, and use the CA certificate to verify the application signature. Customized production by customers, the signature verification scheme cannot be changed after leaving the factory

Abstract

The invention relates to a method for realizing APK unified signature by using three-level certificate authentication, which adopts a three-level certificate chain including a CA certificate, a user equipment certificate, a user root certificate and a user working certificate to carry out CA authentication, the CA certificate is integrated into firmware, and the user equipment certificate is preset into equipment when the equipment leaves a factory. The POS terminal integrated with the scheme can download different user terminal certificates to support diversified application signature verification requirements of users, such as SM3WithSM2, SHA3-256WITHRSA and the like, manufacturers do not need to customize versions for clients due to the signature verification scheme, version managementis facilitated, and development cost is reduced.

Description

technical field [0001] The invention relates to methods for signature and signature verification, in particular to a method for adding a custom signature verification in an APK integrity verification mechanism in Android and performing certification center (CA) authentication on application certificates. Background technique [0002] Every application running on the Android platform must be signed by the developer. Applications without a signature or with a damaged signature cannot be installed on an Android device. Android applications can currently be signed by third parties (original equipment manufacturers (OEM), operators, other application markets), and can also be self-signed. Android provides the function of using self-signed certificates for code signing. Applications do not have to be signed by the core authority , does not perform Certificate Authority (CA) authentication on the application certificate. [0003] At present, Android supports three signature scheme...
