Method for accessing intelligent equipment by using timeliness password in semi-offline environment

Abstract

The invention discloses a method for accessing intelligent equipment by using a timeliness password in a semi-offline environment. According to the method, a small amount of synchronization information needs to be maintained at an intelligent device and a server side, and a clock chip needs to be added at the intelligent device side to maintain current time information. When a user applies to obtain the aging password, the method encodes the effective time into a bit string with the length of 13, embeds the bit string into a signature bit string, and converts the signature bit string into a decimal password. After the intelligent equipment receives the password, whether the user identity authentication is successful or not is determined by verifying whether the signature and the time are valid or not. According to the method, the requirement that a user uses a timeliness password to access the intelligent equipment under the long-time offline condition can be met only by adding a little hardware and synchronizing the information of the intelligent equipment and the server side under the necessary condition, and the method has a wide application prospect in the field of the Internetof Things.

Description

technical field [0001] The invention belongs to the technical field of mobile Internet and smart devices, and provides a method for accessing smart devices by using a time-sensitive password in a semi-offline environment. It specifically involves the permission access control of smart devices in the mobile Internet environment. Background technique [0002] With the rapid popularization of the mobile Internet and the Internet of Things, smart devices are widely used in various industries. During the working process, these smart devices often need to communicate with the server to complete data exchange. However, due to physical constraints, it is difficult for many smart devices to ensure that they can communicate with the server at any time, which makes it difficult for users to identify themselves. When a user inputs identity verification information to a smart device, the smart device can only complete the verification through locally cached data, which cannot guarantee ...

Problems solved by technology

In such scenarios, smart devices are often required not only to have time-sensitive judgments on passwords, but also to: 1) Passwords should not be too long, making it difficult for users to memorize and use them; 2) Passwords must be secure and not easily cracked by violence

3) Do not substantially increase the cost or power consumption of smart devices
