Engineering Contradiction Analysis
1Reliability
If conventional security schemes are implemented in IoT devices, then data transmission security is improved, but device resource consumption (computation and storage) increases beyond IoT device capabilities
Solution Approach 1:
The security system is segmented into two parts: a lightweight authentication protocol for resource-constrained IoT devices, and a more robust encryption/decryption system for the server. The IoT devices only perform lightweight operations (generating authentication tokens, encrypting with pre-shared keys), while the server handles heavier computational tasks (verifying tokens, decrypting data), thus maintaining security without overburdening IoT device resources.
Solution Approach 2:
A pre-shared key mechanism acts as an intermediary between IoT devices and the server, established during device onboarding. This pre-established trust relationship eliminates the need for complex real-time key exchange protocols during data transmission, reducing computational overhead while maintaining security. The pre-shared key serves as a mediator that enables secure communication without requiring heavy cryptographic operations at the IoT device level.
2Use of energy by moving object
If lightweight security schemes are used in IoT devices, then resource consumption is reduced, but vulnerability to cyber attacks (e.g., MITM attacks) increases
Solution Approach 1:
Security credentials (pre-shared keys, device identifiers, and authentication tokens) are established and configured in advance during the device onboarding process, before the devices deploy to the network. This preliminary setup ensures that even lightweight devices have strong security credentials ready before they begin transmitting data, preventing vulnerabilities like MITM attacks without requiring heavy real-time security operations.
Solution Approach 2:
The server provides feedback by verifying authentication tokens and validating device identities during the connection establishment phase. This feedback mechanism ensures that only authenticated devices can join the network and transmit data, creating a security layer that protects against unauthorized access and MITM attacks while keeping the IoT device operations lightweight.
3Reliability
If authentication and encryption protocols are implemented for all data transmissions, then data confidentiality and integrity are improved, but communication overhead and transmission time increase
Solution Approach 1:
Security operations are segmented into two phases: a one-time heavy setup phase during device onboarding (where pre-shared keys and authentication credentials are established), and a lightweight operational phase during data transmission (where only simple token verification and pre-shared key encryption are used). This segmentation ensures that confidentiality and integrity are maintained while minimizing communication overhead during actual data transmission.
Solution Approach 2:
All heavy authentication and key exchange operations are performed in advance during the device onboarding phase. The pre-shared keys and authentication tokens are established before data transmission begins, so that during normal operation, only lightweight verification and encryption tasks are required, significantly reducing communication overhead and transmission time while maintaining security.
4Reliability
If complex key exchange protocols are used between multiple entities, then mutual authentication is achieved, but computational cost and energy consumption increase
Solution Approach 1:
The authentication system is segmented so that IoT devices perform only lightweight authentication (sending pre-configured device identifiers and authentication tokens), while the server performs the heavier verification tasks (validating tokens against its database, verifying pre-shared keys). This segmentation achieves mutual authentication without requiring complex bidirectional cryptographic operations at the resource-constrained IoT device level.
Solution Approach 2:
Pre-shared keys and authentication tokens serve as intermediaries that enable mutual authentication between IoT devices and the server without requiring complex real-time key exchange protocols. These pre-established credentials mediate the authentication process, allowing both parties to verify each other's identity with minimal computational overhead at the IoT device level.

AI summary
A secure data transmission system between multiple IOT entities includes a base station with a first program instruction in a first processing unit, and multiple clusters. Each cluster includes a cluster head having a second program instruction in a second processing unit. The cluster head is communicatively connected to the base station. Each cluster further includes multiple cluster members. Each member has a third program instruction in a third processing unit and is communicatively connected to the cluster head with a single-hop connection and is configured to sense multiple data entities. First, second and third program instructions include, a first, a second and a third data transmission protocol respectively, for data transmission, between the base station and the cluster head, between the cluster head and each cluster member and between the base station and the cluster head, and between the cluster member and the cluster head of the cluster, respectively.
