Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0065] Such as figure 1 As shown, the digital certificate application method according to the first embodiment of the present invention includes the following steps:

[0066] (1) The first device generates the first key pair (pk 1 ,sk 1 ), from the first key pair (pk 1 ,sk 1 ) to derive the first public key pk 1 , the first public key pk 1 Packing with the identification name of the digit...

Abstract

The invention discloses a digital certificate application method. The method comprises: a first device generates a first key pair, derives a first public key from the first key pair, packages the first public key with an identification name of a digital certificate user to generate first certificate request information, and sends the first certificate request information to a second device; a second device generates a second key pair, parses out a first public key from the received first certificate request information, and carries out operation by using a second private key in the second key pair and the first public key so as to generate a complete certificate public key; and the second device uses the complete certificate public key to replace the first public key in the first certificate request information so as to generate second certificate request information. Therefore, technical problems that usage complexity of the user is high because the existing digital certificate user needs to carry hardware safety equipment to complete digital certificate operation and two sides can not apply for digital certificates cooperatively in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of information security, and more specifically relates to a digital certificate application method. Background technique [0002] At present, business systems mostly use Public Key Infrastructure (PKI) systems based on digital certificates to ensure business data security. Digital certificates are issued by Certificate Authority (CA) or third-party CAs. The public key cryptography mechanism with digital certificate as the core can encrypt and decrypt information transmitted on the network, digitally sign and verify, so as to ensure the confidentiality and integrity of messages transmitted on the network, the authenticity of transaction entities, and the non-repudiation of signatures To ensure the security of network applications. [0003] In the traditional digital certificate application process, the certificate applicant generates a key pair and a certificate request file (Certificate Signing Request, referred to a...
