Abstract

The invention relates to the technical field of information security, discloses an application program processing method and device, a terminal and a storage medium, and solves the problem that the security legality of an application program cannot be ensured when the application program is installed in an intelligent terminal in the prior art. The method comprises: when an installation instruction of an application program is received, digital signature information in the application program is extracted, and the digital signature information is a digital signature carried out on an executable code file corresponding to the application program through signature parameters; verifying the digital signature information by utilizing a verification parameter, wherein the verification parameteris associated with the signature parameter; and when the digital signature information passes the verification, installing the application program. The embodiment of the invention is suitable for theinstallation process of the application program.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an application program processing method, device, terminal and storage medium based on a combined public key. Background technique [0002] At present, when an application is installed on a smart terminal, it will receive a notification from the system whether to authorize the application to access user sensitive data (for example, short message content, address book content, etc.), and the user only needs to make a choice of yes or no . However, due to the endless emergence of malicious applications, the legitimacy of the developers of the applications to be installed cannot be guaranteed. If the applications are maliciously attacked and tampered with, it will bring security problems to users. Contents of the invention [0003] The purpose of the present invention is to provide an application program processing method, device, terminal and storage medium ...
