Technical Field
The invention belongs to the technical field of digital certificates, and particularly relates to a method, a system, a storage medium and a mobile terminal for issuing a digital certificate.
Background
The digital certificate is a string of data which marks the identity information of each communication party in Internet communication and provides a way for verifying the identity of the communication entity on the Internet.
A digital certificate is a file containing public key owner information and a public key that is digitally signed by a certificate authority. The simplest certificate contains a public key, a name, and a digital signature of the certificate authority. A further important feature of digital certificates is that they are valid only for a certain period of time.
The digital certificate is an authoritative electronic document, and can be issued by a third party organization with a fair authority, namely a CA (for example, CA companies in all parts of China) center, and can also be issued by an enterprise-level CA system. The encryption technology (security technologies such as encryption transmission, digital signature, digital envelope and the like) taking the digital certificate as a core can encrypt and decrypt information transmitted on the network, and verify the digital signature and the signature, so that the confidentiality and the integrity of the information transmitted on the network and the non-repudiation of transactions are ensured.
The digital certificate may be used to: the method comprises the following steps of sending secure e-mails, accessing secure sites, online securities trading, online bidding and purchasing, online working, online insurance, online tax, online signing, online banking and other secure electronic transaction processing and secure electronic trading activities.
A typical digital certificate issuance process includes: the CA center completes verification (name, identification number, etc.) of the true identity information of an individual user, the user generates a secret Key using a dedicated cryptographic device (such as a USB Key), the CA center signs the true identity information of the user and a public Key generated by the user together into a digital certificate, a long validity period (e.g., 1 year) is generally set, and the user stores the digital certificate in the cryptographic device.
There are some problems in the above issuing process: the user identity authentication process is complex, and generally the user needs to go to a handling network point of a CA center to perform face-to-face identity verification, so that the time is long, and the user experience is poor; special password equipment is required, and the cost of the user is increased. In the era of "internet +", this way of issuance is hardly acceptable to users.
