Wireless Message Verification Without Recipient Address
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face challenges in accurately delivering messages without including the recipient's address, which can lead to unnecessary bulk and vulnerability to spoofing attacks, especially in networks like Mobitex and GPRS where address reassignment occurs.
Innovation Solution
The system encodes payload information with verification information using a shared key, allowing the intended recipient to verify the message's integrity without needing the recipient's address, using methods like XOR operations to scramble and descramble verification information within the message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the recipient's address is included in the message header, then the mobile device can accurately assess whether it is the intended recipient, but the message bulk increases and spoofing attacks become vulnerable
Solution Approach 1:
The patent extracts and removes the recipient's address from the message header, eliminating the need for direct address inclusion while maintaining delivery accuracy through alternative verification mechanisms
Solution Approach 2:
The patent introduces verification information as an intermediary element that enables recipient identification without using the traditional address field, allowing accurate message delivery while reducing message bulk
2Quantity of substance
If the recipient's address is removed from the message, then message bulk is reduced and spoofing vulnerability decreases, but the mobile device can no longer accurately assess whether it is the intended recipient
Solution Approach 1:
The patent introduces verification information as an intermediary that replaces the traditional address field, enabling accurate recipient identification without including the recipient's address directly in the message
Solution Approach 2:
The patent changes the parameter used for recipient identification from the recipient's address to verification information, allowing accurate message delivery while reducing message bulk
3Ease of operation
If IP address is used for message readdressing in GPRS network, then message delivery is enabled, but the address can be reassigned to different devices and spoofing becomes possible
Solution Approach 1:
The patent introduces verification information as an intermediary that provides reliable recipient identification in GPRS networks, preventing spoofing attacks while maintaining message delivery capability
Solution Approach 2:
The patent replaces the IP address-based mechanical identification system with a verification information-based system that provides more secure and reliable recipient identification

AI summary
Systems and methods for a wireless communication system used for transmitting and receiving information, the information not containing identification of the information's intended recipient. A method for transmitting payload information, the method comprising providing verification information scrambling a portion of the verification information and transmitting the payload information with the scrambled verification information portion. Also provided is a method for processing transmitted payload information incorporated into an encoded information message with scrambled verification information, the method comprising receiving the encoded information message descrambling at least a portion of the scrambled verification information and comparing said descrambled verification information with predetermined verification information processing said payload information based on said comparison.
