Router Message Interruption Detection for Security Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security systems face issues with false alarms and vulnerabilities due to network failures, impersonation of alarm receivers, and undetected communication losses, which can lead to unauthorized acts going unnoticed.
Innovation Solution
Incorporating a message interruption detection system within routers that monitor the status of alarm receivers and central monitoring stations, using SMS or email alerts to notify users and administrators of communication losses or mismatches, and verifying the MAC identifier of alarm receivers to ensure legitimate message transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alarm systems are used without message interruption detection, then the system is simpler and cheaper to operate, but the system reliability is reduced due to undetected communication losses and network failures
Solution Approach 1:
The system performs preliminary actions by sending test messages through the communication network before actual alarm messages are transmitted. This proactive approach detects potential communication failures, network disconnections, or impersonation attempts before they affect real alarm transmissions, thereby improving reliability without requiring complex real-time monitoring infrastructure
Solution Approach 2:
The system implements feedback mechanisms where the alarm receiver sends acknowledgment messages back to the monitoring system. By analyzing these feedback messages for integrity and authenticity, the system can detect communication losses, network failures, or impersonation attempts. This feedback loop enables reliable detection of message interruptions while maintaining relatively simple system architecture
2Object-affected harmful factors
If MAC identifier verification is implemented to detect impersonation, then security against unauthorized acts is improved, but the processing time and system complexity increase
Solution Approach 1:
The system performs MAC identifier verification as a preliminary check on incoming messages from alarm receivers. By verifying the cryptographic signature or MAC (Message Authentication Code) of each message before processing its content, the system quickly identifies impersonation attempts without requiring complex real-time analysis. This preliminary verification approach enhances security while minimizing processing time overhead
Solution Approach 2:
The system replaces manual or mechanical verification methods with cryptographic verification of MAC identifiers. Instead of relying on time-consuming manual checks or complex behavioral analysis, the system uses efficient cryptographic algorithms to verify message authenticity. This substitution provides rapid, automated detection of impersonation attempts with minimal processing time and system complexity
3Reliability
If communication status monitoring is added to detect network failures, then the reliability of alarm transmission is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The system implements periodic communication status monitoring by sending test messages at regular intervals rather than continuously monitoring the communication channel. This periodic approach detects network failures, disconnections, or message interruptions while consuming significantly less energy than continuous monitoring. The system can adjust the monitoring interval based on risk levels and operational requirements, balancing reliability improvement with energy conservation

AI summary
A method and apparatus include a processor of an Internet router monitoring a parameter of messages between a security panel that protects a secured area and a central monitoring station of the secured area, detecting an interruption in the messages by comparing the parameter with a threshold value, and notifying at least the central monitoring station of the interruption via an e-mail or SMS message, wherein the interruption includes one of disconnection of the security panel, disconnection of the central monitoring station, and impersonation of the central monitoring station.
