Quantum Service Authorization for 5G Network Slicing Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G network slicing faces security threats such as denial-of-service attacks, performance attacks, data breaches, and unauthorized access, particularly during the 'run stage' of network service slices, which can compromise resource consumption and lead to further vulnerabilities.
Innovation Solution
The implementation of a Quantum Service Authorization Management (QSAM) system that registers user equipment, generates quantum tokens by encoding base station and user equipment identifiers into tensor networks, and verifies these tokens to authorize service requests, thereby enhancing security through quantum entanglement principles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum tokens are generated and verified for each service request, then security against unauthorized access and DoS attacks is improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent replaces traditional classical authentication mechanisms with quantum-based authentication. Quantum tokens utilize quantum entanglement and superposition principles to create authentication tokens that are computationally secure against classical and quantum attacks. The quantum random number generator and quantum key distribution protocols substitute for conventional cryptographic systems, providing enhanced security through quantum mechanical properties rather than computational complexity.
Solution Approach 2:
The patent changes the fundamental parameters of authentication from classical bits to quantum states. By encoding authentication information in quantum states (qubits) rather than classical binary data, the system achieves higher security through quantum indeterminacy and entanglement. The quantum tokens are generated using quantum random number generation, transforming the authentication parameter space from classical to quantum domain, making token forgery impossible under current physical laws.
2Object-affected harmful factors
If quantum token verification is performed for each service request, then protection against resource consumption attacks is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary quantum token generation and verification setup during network slice establishment and user authentication phases. Quantum tokens are pre-generated and distributed to authorized users and network elements before actual service requests occur. This preliminary authentication setup reduces the burden during runtime, allowing faster verification decisions while maintaining quantum security throughout the service lifecycle.
Solution Approach 2:
The patent implements feedback mechanisms where network elements verify quantum tokens and provide authorization decisions back to requesting entities. The quantum verification system provides immediate feedback on token validity, enabling rapid authorization decisions. This feedback loop allows the system to quickly identify and reject unauthorized requests without requiring extensive processing, improving both security and response time through efficient quantum verification protocols.

AI summary
Systems and methods for verifying a service request by a quantum service authorization management (QSAM) in a 5G network with a plurality of service slices used by a plurality of base stations to provide services to a plurality of user equipment include registering the plurality of user equipment, generating a token containing information identifying a first base station of the plurality of base stations providing services to a first user equipment of the plurality of user equipment through a first service slice of the plurality of service slices, sending the generated token to the first user equipment, receiving the generated token when the first user equipment requesting service from the first base station using the first service slice, granting the service request if the received token is verified as valid, and denying the service request if the received token is verified as invalid.
