The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Thus, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.

In the modern society, security has become a hot issue of people's attention. Intelligent devices such as access control devices and mobile phone terminals increasingly pay more attention to the safety of the intelligent devices. Traditional district or hotel security mode adopts access control system, and the user opens the door or takes advantage of the ladder through the mode of punching the card, but there is the drawback in the access control card, for example easily loses, easily forgets to carry or easily steals, has the potential safety hazard. In addition, the traditional unit door or the family can be opened by adopting a password mode, the password is required to be preset in security measures based on the password, when the traditional unit door or the family is used, a user needs to input the password for authentication, and if the password is consistent, the authentication is passed; if the passwords are not consistent, authentication fails. However, such a cryptographic scheme has two major drawbacks: firstly, passwords are easy to forget; secondly, the password is easy to leak, so that security measures based on the password also have certain potential safety hazards.
