Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0017] In order to meet the requirements of the national secret policy, the public-private key pair is divided into a signature key pair d and an encryption key pair r; the signature key pair d is controlled by the user (the part generated by the user himself), and the encryption key pair r is generated by the self-generated key system The authentication platform (hereinafter collectively referred to as "Platform C", which uses a cipher machine to generate a key pair, or a random number generator) generates and hosts it for national supervision. Such as figure 1 As shown, the user generates a partial signature key pair d through the usbkey with the national secret chip 1 , put the partial sign...

Abstract

The invention discloses an implementation method for self-generation of a key pair. The signing key pair of a user comprises two parts, namely, a signing key pair part generated through ausbkey and a signing key pair part regenerated by an authentication platform for the user after the user completes registration and authentication on the authentication platform of a key self-generation system, the two signing key pair parts are fused, and the final signing key pair of the user is formed. With the adoption of the implementation method, the key pair can be self-generated on the premise that no CA certificate is implanted, the trouble that the user has to apply the CA certificate is avoided, expenses are saved, the key self-generation system can provide an encryption key pair for the user for free, data are transmitted safely through public and private key pairs, accordingly, encryption, decryption, safety information passing, information effectiveness verification and other work can be realized for common users, the operation process is simple, no complicated procedures are required, shorter time is required, and the method is convenient to use and suitable for popularization and use among common people.

Description

technical field [0001] The invention relates to the technical field of cryptography, in particular to a method for realizing a self-generated key pair of a usbkey with a national secret chip without implanting a CA certificate. Background technique [0002] Internet applications are very common in the real world, and network information security has become a major focus of attention. At present, an effective means to effectively protect online information transmission and enhance transmission security is to encrypt with digital certificates, but in the form of digital certificates, It is necessary to apply for a digital certificate to the digital certificate management authority (CA) in advance, which has many procedures and a long process, and often cannot meet the timeliness requirements of commercial contracts. Digital certificate applicants must apply to CA for digital certificates; digital certificate applicants must submit written application materials to CA and attach...
