Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Address resolution protocol (ARP) entries are vulnerable to tampering during network communications, leading to ARP cache poisoning and man-in-the-middle attacks, necessitating a secure and efficient protection mechanism.
Innovation Solution
A system that identifies ARP cache tables, determines firewall properties, executes smart contracts with authorization protocols and homomorphic encryption, and applies network segmentation to protect ARP cache tables from tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ARP cache tables are protected using traditional security measures, then security against tampering is improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent transforms ARP cache protection from a static security model to a dynamic one by continuously monitoring firewall properties and automatically adjusting protection levels. The system changes parameters such as encryption activation, access control strictness, and monitoring intensity based on real-time anomaly detection, thereby improving security without permanently increasing system complexity
Solution Approach 2:
The system implements self-protection mechanisms where the ARP cache table automatically detects anomalies in firewall properties and triggers its own protection protocols through smart contracts. The system monitors its own security state and autonomously activates decryption, access control, or other protective measures without external intervention, reducing the need for complex external security infrastructure
2Measurement precision
If manual security monitoring and protection measures are implemented, then detection accuracy is improved, but time consumption and operational overhead increase
Solution Approach 1:
The system establishes a continuous feedback loop where firewall properties are monitored, anomalies are detected, and protection measures are automatically adjusted based on the detected anomalies. The smart contracts receive feedback from the monitoring system and automatically modify their behavior, creating a closed-loop control system that improves detection accuracy while maintaining rapid response times through automation
Solution Approach 2:
The system pre-configures smart contracts with multiple protection protocols and decision-making logic before security incidents occur. When anomalies are detected, the pre-programmed contracts automatically execute the appropriate protection measures without requiring manual analysis or decision-making, thereby maintaining high detection accuracy while minimizing response time
3Reliability
If encryption and authorization protocols are continuously applied, then data security is improved, but computing resource consumption increases
Solution Approach 1:
The system dynamically adjusts the application of encryption and authorization protocols based on real-time assessment of firewall properties and detected anomalies. Protection intensity varies from minimal to maximum depending on the security context, allowing the system to maintain high data security when needed while conserving computing resources during normal operations. The smart contracts activate cryptographic operations only when anomalies are detected or security risks are present

AI summary
Systems, computer program products, and methods are described herein for implementing real time protocol modifications for address resolutions protocols in a network environment. The present disclosure is configured to identify an address resolution protocol (ARP) cache table comprising an internet protocol (IP) address and a media access control (MAC) address for a communication mapping(s); determine a firewall property(ies) of the ARP cache table for the communication mapping(s); compare the firewall property(ies) to at least one normal firewall property and determine whether the firewall property(ies) is anomalous compared to the normal firewall property(ies); automatically execute a smart contract, wherein the smart contract comprises an authorization protocol(s) for the ARP cache table and an execution of a homomorphic encryption for the ARP cache table; and protect the ARP cache table based on the execution of the smart contract with the authorization protocol(s) and the homomorphic encryption.
