Power terminal identity authentication method and system based on trusted behavior sequence

Abstract

The invention relates to the field of computers, in particular to a power terminal identity authentication method based on a trusted behavior sequence, which comprises the following steps: acquiring terminal behavior data in real time, and inputting the terminal behavior data acquired in real time into a terminal identity authentication module for authentication; when the authentication fails, ending identity authentication; when the authentication succeeds, outputting that the terminal identity authentication succeeds, and updating the terminal behavior mode in the terminal identity authentication module. The terminal behavior mode similarity is matched through a behavior sequence similarity measurement method, the identity of the terminal is confirmed, and the security authentication ofthe terminal is guaranteed in the mode of calculating the terminal behavior similarity. Multiple pairs of sequences are updated and mined, so that the long-term effectiveness of the method is achieved.

Description

technical field [0001] The invention relates to the computer neighborhood, in particular to a power terminal identity authentication method and system based on trusted behavior sequences. Background technique [0002] With the widespread application of smart devices in smart grids, power customers are increasingly connected with the information world. The smart grid can support the two-way interaction of information flow between power customers and equipment. This two-way interaction ensures the real-time transmission of power consumption data based on customer needs, but the security problems at the user end are becoming more and more obvious. Among the security issues, the leakage of private information of power customers is particularly prominent, which is closely related to everyone, and this is a limiting factor for the further development of smart grids. Therefore, it is of great significance to carry out research on privacy protection of power customers in smart grid...

AI Technical Summary

Problems solved by technology

[0004] The traditional terminal identity authentication technology adopts the user name and password authentication method, which will leak the sensitive information of the user and infringe on the privacy information such as the user's identity status, behavior habits, and electricity consumption characteristics.

Moreover, the network data information is becoming more and more abundant, while the terminal resources in the power network environment are limited, the computing power is insufficient, and the time for terminal identity authentication is too long, which increases the possibility of user information leakage
