Secret key devices for supporting anonymous authentication, generation method and unlocking method thereof

Abstract

The invention provides identification authentication-based technology, and relates to secret key devices for supporting anonymous authentication. Identification secret keys generated by anonymous identifiers are stored in the secret key devices. The generation method of the secret key devices for supporting the anonymous authentication comprises the following steps of: defining and generating at least one anonymous identifier; defining a seed secret key pair, wherein the seed secret key pair consists of a seed public key and a seed private key; allowing the anonymous identifiers to generate identification private keys corresponding to the anonymous identifiers respectively through the seed private key; and writing the generated identification private keys into each secret key device. The invention also provides a back-up unlocking method of the dual secret key devices. The devices and the method can support requirements of social and publics on anonymous safety service, and reduce theapplication threshold of the authentication technology greatly.

Description

technical field [0001] The invention relates to identification-based authentication technology, in particular to a key device based on a combined public key system and supporting anonymous authentication, a generation method and an unlocking method thereof, and belongs to the technical field of information security. Background technique [0002] At present, network and information technology have penetrated into all aspects of people's production and life. How to protect the authenticity, security, and responsibility (non-repudiation) of information has become a common concern of the government and society. In order to meet the requirements of social development, technology manufacturers have developed authentication systems, such as public key infrastructure (PKI) based on public key digital certificates and authentication systems based on combined public key (CPK) technology identification, as well as authentication systems based on the above systems A series of applicatio...

Problems solved by technology

However, self-construction and management of certification centers is a heavy burden for small and medium-sized enterprises, and it is even more unattainable for individual users. However, using services provided by third parties requires a series of complicated rules and corresponding costs. It is difficult for many small and medium-sized enterprises and individual users to afford

[0005] 3. Although many countries have established commercial certification centers and provide services to enterprises and the public, it is difficult for these centers to provide mutual certification, which causes a lot of inconvenience to enterprises and individual users who purchase services

In addition, since the authentication center holds all the user's private keys (for the purpose of key recovery) and the user's personal registration information, once there is a problem with the center, it will directly affect the service to the user, and even endanger the user's privacy and security
