Embodiment Construction

[0059] At first the definitions and descriptions of terms involved in the present invention:

[0060] Key generation base: mainly includes public key generation base and private key generation base.

[0061] Public key generation base: mainly includes root public key generation base and scope public key generation base.

[0062] Private key generation base: mainly includes root private key generation base and scope private key generation base.

[0063] Root key generation base: mainly includes root public key generation base and root private key generation base.

[0064] Scope key generation base: mainly includes scope public key generation base and scope private key generation base.

[0065] In the present invention, a unified key generation parameter can be constructed based on the elliptic curve algorithm, and then a large-scale user key can be obtained from the key generation parameter through a combination algorithm by using the user identification as an input parameter...

Abstract

The invention discloses authentication system, including a user's terminal body for applying user's label certification by user's label information; a subsystem key generation basis to generate a user key generation basis for user key accounting including a public key generation basis and a private key generation basis; a certification management subsystem for responding the application of the user's terminal body to generate the public key and private key of the user with the user's label, the user key generation basis and the user's label combination accounting, and to sign the user's label certification including the public key and private key of the user and send them the certification to the applied user's terminal body. In addition, the invention discloses a corresponding method of releasing user's label certification. The invention takes advantages of low cost without a third party certifying, achieving key producing with scale and low requirement to the system resource and scale.

Description

technical field [0001] The invention relates to the technical field of security authentication, and more specifically, the invention relates to an authentication system and a method for issuing user identification certificates. Background technique [0002] With the continuous development of network and informatization applications, security issues have become the focus of network and informatization work. Authentication technology to ensure transaction security is one of the main fields of information technology. The industry urgently needs to realize security authentication and establish a trusted network system so that Provide services such as authenticity certification, responsibility certification, and digital signatures for network transactions. On the other hand, after more than ten years of development, there are currently two popular authentication systems in the world: one is based on public key infrastructure (PKI) technology The second is the authentication syste...
