Abstract

The invention puts forward a cross digital signing method and a cross digital signing system for application software under a domestic operating system. The method comprises the following steps: a software developer copies to-be-released software to a special signing device; the special signing device signs the to-be-released software; the special signing device releases signing software and a signing certificate generated to a special management device; and the special management device signs the signing software for the second time in a cross manner, generates cross signing software and a cross signing certificate, and releases the cross signing software and the cross signing certificate to an application store. The invention further puts forward a corresponding cross digital signing system. Through cross signing using a special signing device, the reliability of to-be-released software is strengthened, and adverse consequences caused by illegal certificate misappropriation are prevented. Moreover, software developer identity management is realized.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to a cross digital signature method and system for application software under a domestic operating system. Background technique [0002] With the development of computer technology, the strengthening of the concept of information security, and the emphasis on security and controllability of nationalization, the research and development and popularization of domestic operating systems have reached unprecedented popularity in recent years, laying a solid foundation for the realization of independent research and development of security and controllability. The promotion and application of domestic operating systems is becoming more and more important. One of the main factors that currently restricts the comprehensive popularization of domestic operating systems is the limited number of application software. In the future, it is urgent to strengthen the development and promotion...
