Wireless Terminal Binding Authentication Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless terminal and service providing client systems lack an effective method to restrict binding between devices, allowing for random associations that can lead to unauthorized usage and loss of operator benefits.
Innovation Solution
Implementing an interactive authentication mechanism between service providing clients and wireless terminals using random numbers and encryption algorithms to determine legal binding objects, ensuring that only authorized devices provide and receive services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If random binding between service providing client and wireless terminal is allowed, then device compatibility and ease of operation are improved, but operator benefits are lost and unauthorized usage increases
Solution Approach 1:
The patent applies preliminary action by performing authentication before service provision. The service providing client transmits authentication information to the wireless terminal, and only after successful verification does the client proceed to provide services. This prevents unauthorized devices from accessing services while maintaining ease of operation for authorized devices.
Solution Approach 2:
The patent implements feedback through the authentication response mechanism. The wireless terminal responds to authentication information with response information, allowing the service providing client to verify whether the terminal is legal. This feedback loop ensures binding authorization while maintaining operational simplicity through automated verification.
2Reliability
If authentication mechanism is implemented, then binding authorization is improved, but system complexity increases
Solution Approach 1:
The patent applies self-service by having the wireless terminal autonomously perform authentication using its own authentication information. The terminal independently verifies the service providing client's legality without requiring external intervention, thereby achieving reliable binding authorization while minimizing the complexity burden on the service providing client.
Solution Approach 2:
The patent utilizes parameter changes by employing encryption algorithms to transform authentication information into encrypted forms. The service providing client encrypts authentication information using a first encryption algorithm, and the wireless terminal uses a second encryption algorithm, creating secure parameter transformations that enhance authorization reliability without significantly increasing operational complexity.
3Reliability
If encryption algorithms are used for authentication, then security and binding authorization are improved, but processing time and energy consumption increase
Solution Approach 1:
The patent applies partial action by implementing authentication only at critical binding moments rather than continuously. The authentication information is transmitted and verified when the service providing client needs to establish service with the wireless terminal, rather than maintaining constant authentication processes, thereby reducing time loss while maintaining security.
Solution Approach 2:
The patent uses copying by having the wireless terminal store and reuse authentication information locally. The terminal caches the authentication response information, allowing rapid verification without repeatedly performing full authentication processes, thus reducing authentication time while maintaining strong security through encrypted copies of authentication data.

AI summary
The disclosure discloses a service providing client, a wireless terminal and a method for implementing binding. The service providing client comprises a transmission module, which is configured to transmit authentication information to the wireless terminal (701); a judgment module, which is configured to judge whether the wireless terminal is a legal binding object according to a response of the wireless terminal for the authentication information (702); and a processing module, which is configured to provide service to the wireless terminal (703) if the wireless terminal is a legal binding object, otherwise, restrict the service provided to the wireless terminal.
