Multipath Message Encoding Against Unknown DoS Attacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G systems are vulnerable to unknown denial-of-service attacks, which can prevent the delivery of mission-critical messages, leading to severe communication degradation.
Innovation Solution
A multipath communication approach that encodes messages into multiple packets and routes them through different paths, ensuring message recovery even if some paths are compromised by denial-of-service attacks, using lightweight XOR operations and ad-hoc coding schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are transmitted through multiple paths with encoding, then message delivery reliability is improved against denial-of-service attacks, but device complexity and processing overhead increase
Solution Approach 1:
The message is divided into multiple packets that are transmitted through different communication paths. Each packet is independently encoded and can be received through separate routes, ensuring that if some paths are blocked by denial-of-service attacks, other packets can still reach the destination and allow message reconstruction.
Solution Approach 2:
The patent employs lightweight encoding schemes that transform the message into multiple packets with specific parameters (such as sequence numbers and redundancy bits) that enable efficient decoding. By optimizing these parameters and using simple algebraic operations rather than complex cryptographic methods, the system achieves reliable message delivery while maintaining low processing overhead.
2Speed
If lightweight encoding schemes are used for message protection, then processing speed is improved, but security against sophisticated attacks may be reduced
Solution Approach 1:
The patent uses disposable, lightweight encoding schemes that are computationally inexpensive and can be rapidly applied to messages. These encoding methods use simple mathematical operations (such as XOR and modular arithmetic) that can be executed quickly on resource-constrained devices like UAVs, while still providing sufficient protection against denial-of-service attacks through the combination of multiple paths and packets.
Solution Approach 2:
The security mechanism combines multiple elements into a composite approach: lightweight encoding schemes are integrated with multipath transmission and packet redundancy. This composite strategy achieves both fast processing (from the lightweight encoding) and robust security (from the layered approach combining multiple paths, packets, and error correction mechanisms).

AI summary
Presented herein is an effective protection method against unknown and unanticipated denial-of-service attacks and guarantee mission critical message delivery. Multipath communication may be leveraged as a preventive device-centric mechanism to ensure message deliveries in the event of unknown denial-of-service attacks. The mechanism may complement other device-centric mitigation techniques as the mechanism does not wait for the detection of adversaries in the network and is attack-agnostic. In particular, the technique may be effective against a wide range of denial-of-service attacks at any protocol layer.
