Abstract

The invention provides a method of generation and backup of a digital certificate and a private key. The method of generation and backup of the digital certificate and the private key comprises that a data center is in network connection with a personal computer (PC) end card issuing tool, the PC end card issuing tool is respectively connected with a certificate generation terminal and a card issuing terminal, a signature card is inserted in the card issuing terminal, a backup card is inserted in the certificate generation terminal, root certificate data, working certificate data and related personnel information are stored in the data center, the PC end card issuing tool and the data center carry out interactive through an ethernet network, the PC end card issuing tool writes the digital certificate generated by the certificate generation terminal in the signature card, can safely and rapidly formulate the format of the digital certificate, and meanwhile can recover private key data corresponding to backup root certificates, and facilitates unified management.

Description

technical field [0001] The invention relates to a signature technology of an intelligent terminal application software installation program, in particular to a method for generating and backing up a digital certificate and a private key. Background technique [0002] With the advent of the intelligent era, the development of smart terminals (mobile phones, POS, TVs and other terminals that can install smart applications) is also accelerating. The development of smart terminals has also brought continuous innovation of application software. On the smart terminal, users can realize more functions by installing their favorite application software. However, due to the diversity of application software on the network, the security of smart terminals is also facing great challenges. Usually different application software is designed by different software providers or software designers, and the functions of various application software are also different. In recent years, due to...
