Bidirectional authentication method between authentication terminal and host and device

Abstract

The invention provides a bidirectional authentication method between an authentication terminal and a host, which comprises the steps that the host verifies the identity of the authentication terminal by identifying secret key information in the authentication terminal, and the authentication terminal verifies the identity of the host by identifying partial hardware identification or all the hardware identification in the host. A device for implementing the method comprises the host and the authentication terminal, the host is internally provided with a reading module for reading the secret key information of the authentication terminal, a host database for storing secret key information, and a judging module for comparing the secret key information with the secret key information stored in the database, and the authentication terminal comprises a reading module for reading hardware identification of the host, an authentication terminal database for storing hardware identification in the host and secret key information, and a judging module for comparing the read hardware identification with the hardware identification stored in the authentication terminal database. The bidirectional authentication process can become simpler and more convenient without applying plenty of encryption algorithms and logical algorithms.

Description

[0001] technical field [0002] The invention relates to an authentication method, in particular to a two-way authentication method, especially a two-way authentication method and device between an authentication terminal and a host. [0003] Background technique [0004] At present, generally, an external encryption device is used as the key for starting the software. The host with the software installed only needs to verify the identity of the authentication terminal to determine that the user authority is legal, and then the software can be started or subsequent operations can be performed. In the case of one-way authentication, if the software is installed on other hosts and has an authentication terminal at the same time, the software can run on other hosts. However, when the authentication terminal is lost, if the person who picks up the authentication terminal cracks the authentication terminal, the interests of the original authentication terminal holder will be th...

Problems solved by technology

However, when the authentication terminal is lost, if the person who picks up the authentication terminal cracks the authentication terminal, the interests of the original authentication terminal holder will be threatened.

[0005] In order to solve the above problems, some two-way authentication methods have appeared. However, the existing two-way authentication methods generally need to cooperate with a large number of encryption algorithms or logic algorithms before they can be implemented. Therefore, the authentication process is very complicated. If one of them If there is a problem with the algorithm, it will affect the subsequent authentication process, thus affecting the final authentication result.
