Wireless Link Establishment Using Protected Service Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face security vulnerabilities in direct device communication, where service codes and user information in connection messages are unprotected, allowing attackers to sniff and compromise security, leading to resource wastage in mitigating attacks.
Innovation Solution
Implementing protection mechanisms such as scrambling and encryption of service codes and user information in connection messages to establish secure links between devices, using scrambling codes and encryption keys to ensure only authorized devices can decipher the protected service codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service codes and user information are transmitted unprotected in connection messages, then device complexity and processing resources are reduced, but security reliability deteriorates allowing attackers to sniff and compromise communications
Solution Approach 1:
The patent applies preliminary action by performing scrambling and encryption of service codes and user information before transmission in connection messages. The transmitting device prepares protected versions of these codes in advance using scrambling codes and encryption keys, so that when messages are exchanged during link establishment, the sensitive information is already secured against sniffing attacks without requiring complex real-time security processing during communication.
2Reliability
If scrambling and encryption protection mechanisms are implemented for service codes and user information, then security reliability improves, but device complexity and processing resource consumption increase
Solution Approach 1:
The patent reduces processing resource consumption during active communication by performing all scrambling and encryption operations in advance during the link establishment phase. The transmitting device generates protected service codes and encrypted user information beforehand, so that subsequent message exchanges use these pre-protected codes without requiring intensive real-time cryptographic processing, thus minimizing energy and computational resource usage during data transmission.
