Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IoT devices use simple and flexible designs with limited calculation capabilities, then device simplicity and flexibility are improved, but network information security deteriorates
Solution Approach 1:
The patent introduces a control center apparatus as an intermediary that performs authentication and encryption operations. The control center acts as a mediator between the simple IoT device and the reading device, handling the complex security operations that the IoT device cannot perform due to its limited calculation capabilities. This allows IoT devices to remain simple while maintaining security through the intermediary's cryptographic functions.
Solution Approach 2:
The patent extracts the complex authentication and encryption functions from the IoT device itself and places them in the control center apparatus. By separating these security-critical functions from the resource-constrained IoT device, the system maintains device simplicity while centralizing security operations in a more capable system component.
2Reliability
If multiple identification processes and authentication steps are implemented, then network information security is improved, but device complexity and access time increase
Solution Approach 1:
The control center apparatus serves as an intermediary that manages the complexity of multiple authentication processes. Instead of distributing complex authentication logic across all devices, the control center centralizes this functionality, performing device identification code verification and authentication password generation. This maintains strong security through multiple checks while keeping individual device complexity low.
3Reliability
If dynamic encryption technology is used, then information security against theft is improved, but calculation requirements and processing overhead increase
Solution Approach 1:
The control center apparatus acts as an intermediary that performs all dynamic encryption and decryption operations. The IoT device only needs to store and transmit static identification codes, while the control center handles the computationally intensive encryption tasks. This allows strong cryptographic protection without burdening the resource-constrained IoT device with heavy calculation requirements.

AI summary
An Internet-of-Things (IoT) reading device, a method of secure access using the same, and a control center apparatus are provided. The Internet-of-Things reading device includes a network interface and a processor. The network interface is configured to communicate with an Internet-of-Things device located in a communication range. The processor actively obtains, by using the network interface, a device identification code from the Internet-of-Things device, and determines whether the Internet-of-Things device is an approved device according to the device identification code. The processor transmits the device identification code to a control center apparatus to obtain an authentication password while the Internet-of-Things device is identified as the approved device, and transmits the authentication password to the Internet-of-Things device to perform an authentication process by the Internet-of-Things device. The processor obtains, after the authentication process is completed, information from the Internet-of-Things device by using a reading request.
