Multi-person shared key management system based on remote server relay and implementation method thereof

The multi-user co-owner key management system, which uses a remote server for relaying key information, combines a threshold for the number of co-owners and an authentication time window to achieve strong authentication when the network is normal and rapid local unlocking when the network is abnormal. This solves the security and availability problems of traditional access control systems and improves the system's resilience.

AI Technical Summary

Technical Problem

Traditional single-key or single-factor password access control systems cannot meet high security requirements. Centralized server verification is susceptible to network outages, and purely local multi-administrator verification lacks a unified audit and permission change mechanism, making it difficult to meet compliance requirements.

Method used

A multi-user co-owner lock key management system based on remote server relay is adopted. The system configures the threshold N for the number of co-owners and the authentication time window ΔT. Combined with the local multi-administrator verification module and super administrator fault tolerance mechanism of the smart lock control terminal, it realizes remote authorization and local fast unlocking, and has network dependency and local fault tolerance.

Benefits of technology

While ensuring high security, the system improves the availability and resilience of the access control system, combining network dependency with local fault tolerance, and meets the need for rapid unlocking in emergency situations.

Abstract

The application discloses a multi-person shared lock key management system based on remote server relay and an implementation method thereof. The system activates a time window and pushes an authorization notice to the remaining associated administrators after the first administrator triggers an authentication request through a configurable shared person number threshold N and an authentication time window ΔT; only when the identity credentials (including local biometrics and remote dynamic tokens) of N independent administrators received and verified within the window, the server issues an unlocking instruction to the smart lock control terminal. The smart lock control terminal is built-in with a local multi-administrator verification module, supporting remote authorization mode, local authorization mode (directly unlocking when detecting at least M administrators nearby and completing local biometric identification or local PIN / card verification) and fault tolerance mechanism (supplementing missing credentials by a preset super administrator through high-strength authentication). The scheme takes into account high security, network fault tolerance and emergency response capability, and is suitable for enterprises, data centers, finance and other scenarios with strict requirements for access control security.
