Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0032] In order to solve the problems existing in the existing digital certificate issuance process, the present invention provides a secure certificate issuance method based on an intelligent cryptographic key. This method guarantees the security of the certificate issuing process through the issued and legal smart cryptographic key, and in the smart cryptographic key, CA (Certificate Authority) has already written the certificate, and its identity is legal. When LRA holds this smart password key, LRA has corresponding authority, such as application, audit, certificate issuance, etc.

[0033] see figure 1 , the secure certification process based on smart cryptographic keys includes five parts: user, LRA, VRA, RA and CA. First, the user applie...

Abstract

The invention discloses a safe certificate issuing method based on a USB (Universal Serial Bus) key. According to the method, an LRA (Local RA) with the USB key is used for issuing an electronic certificate, wherein a digital certificate issued to the LRA by a CA (Certificate Authority) and digital certificates of the CA and VRA (Virtual RA) are stored in the USB key. According to the method, the issued and legal USB key is used for ensuring the safety of a certificate-issuing process, thereby ensuring the capability of safely passing through Internet, meanwhile avoiding establishing a special route between the RA and the LRA and greatly lowering the cost.

Description

technical field [0001] The invention relates to a computer security technology, in particular to a security issuing method based on an intelligent password key. Background technique [0002] Digital Certificate, also known as digital certificate or digital certificate, is an identification mechanism for computers. With the development of e-commerce applications, electronic certificates will be more widely used. [0003] PKI is a key management platform that follows established standards, and it is a management system that provides encryption and digital signature services and required keys and certificates for network applications. It uses the certificate to manage the public key, and binds the user's public key and other user information (such as name, email, ID number, etc.) The generation, management, storage, issuance, and revocation of certificates are managed, and security services are provided for various applications through the interface extending to the user's lo...
