AI Technical Summary

Technical Problem

Most existing dynamic cryptographic lock systems use one-way verification mechanism, which leads to a reduction in overall system security and lacks dynamic and personalization, and cannot dynamically adjust according to user behavioral habits, usage scenarios and environmental changes.

Method used

A dynamic password lock unlock method based on both parties is adopted. After logging in and verifying the identity through the user equipment, a dynamic password combining time, events, physical characteristics and user behavior data is generated, and encryption and verification is carried out through a cloud server, and two-way identity verification and dynamic password verification are finally realized.

Benefits of technology

The security of the system is significantly enhanced, and by introducing non-traditional factors to enrich the password generation dimensions, making passwords more difficult to predict and crack. At the same time, highly personalized random sequences are generated through machine learning algorithms, and encrypted with the user's unique behavioral patterns, improving the complexity and uniqueness of passwords.

Abstract

The invention discloses a dynamic password lock unlocking method based on verification of both parties, which comprises the following steps: a user logs in an account through equipment, and generates a dynamic password after verifying the identity; after login succeeds, the user equipment generates a dynamic password according to a preset dynamic password generation algorithm in combination with time, events, physical characteristics and user behavior data; the user inputs the generated dynamic password into an application program and selects a lock needing to be unlocked to initiate an unlocking request; the application program sends the unlocking request and the encrypted dynamic password to a cloud server; bidirectional verification is carried out between the user equipment and the lock; the lock decrypts and verifies the dynamic password to confirm the correctness of the dynamic password; after verification is passed, unlocking is executed, and a result is fed back to the user; the cloud end analyzes the data regularly, the system is optimized to improve the safety and the user experience, and the system has the advantages of being high in practicability and safety.
