Digital certificate binding method and system and digital certificate authentication center for common user

Abstract

The invention provides a digital certificate binding method and system and a digital certificate authentication center for a common user. The digital certificate binding method comprises the following steps of: receiving a digital certificate rebinding request which is sent by the common user and carries information of the common user; generating a digital certificate bound with the information of the common user by a first system user, and changing digital certificate information of the common user; examining and verifying the digital certificate information bound with the information of the common user by a second system user; setting operation authority of the common user by a third system user; examining and verifying the operation authority of the common user by the second system user; and if the operation authority is successfully examined and verified, returning the digital certificate to the common user which sends the digital certificate rebinding request. The digital certificate binding method and system provided by the invention have the advantage that a new certificate is generated for binding only after operation of the second system user to the first system user and the third system user is successfully examined and verified when the digital certificate authentication center receives the digital certificate rebinding request sent by the common user.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a digital certificate binding method for ordinary users and a digital certificate authentication center. Background technique [0002] With the rapid development of information network technology, the problem of network security has become the biggest hidden danger of network security, so digital certificate technology came into being. For each user of the system, the digital certificate is equivalent to an electronic ID card, which is stored in a specific storage medium, such as "USB Key". Digital certificates have the functions of authenticity, anti-repudiation and anti-tampering, which can effectively protect and securely transmit the information transmitted by users on the Internet, thus ensuring the security of the transaction process. [0003] When the user cannot use the digital certificate due to loss or damage of the storage medium and needs to replace it, ...
