Abstract
The invention provides an offline digital signature verification method and system for a domestic operating system. The method comprises: an application software digital signature certificate library is established and the digital signature certificate library is integrated into an existing domestic operating system; to-be-installed application software code is loaded, a software HASH value is calculated, and a digital signature part is extracted; whether all certificates in a digital signature certificate chain is legal is determined; if so, whether all certificates in the digital signature certificate chain are within validity is verified; if so, whether all certificates in the digital signature certificate chain are revoked or not is determined; if revoked certificates exist among all the certificates in the digital signature certificate chain, the digital signature is determined to be illegal and does not pass the verification, and exit from installation is carried out; and otherwise, verification is done successfully, a software installation environment is detected, and installation is carried out. Using the method provided by the invention, a problem that off-line signature verification can not be realized by the existing domestic operating system can be solved.
