Solution Overview
Problem
Existing information processing systems fail to maintain communication between IoT devices and a host device when a problem occurs in the information processing apparatus.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing apparatus operates in normal mode to ensure security through decryption, then communication security is improved, but communication continuity deteriorates when power supply fails
Solution Approach 1:
The information processing apparatus dynamically switches between multiple operation modes (normal mode, energy saving mode, and pass-through mode) based on power supply status. The control unit monitors power supply conditions and transitions between modes to maintain communication continuity while balancing security requirements, thereby resolving the contradiction between security and continuity.
Solution Approach 2:
The system changes operational parameters by switching between different modes of operation. In energy saving mode, the apparatus reduces processing intensity to maintain security with lower power consumption. In pass-through mode, it changes the decryption parameter to bypass security processing, allowing continuous communication when power is insufficient for full security operations.
2Use of energy by moving object
If the information processing apparatus operates in energy saving mode to reduce power consumption, then energy efficiency is improved, but communication reliability deteriorates
Solution Approach 1:
The control unit dynamically adjusts the operation mode based on real-time power supply status and communication requirements. When power is abundant, the system operates in normal mode for full security processing. When power becomes constrained, it transitions to energy saving mode to reduce consumption while maintaining acceptable communication reliability through reduced but continuous operation.
Solution Approach 2:
In energy saving mode, the apparatus performs partial security processing rather than complete decryption, maintaining sufficient reliability for the given power constraints while reducing energy consumption. This partial action approach allows the system to maintain basic communication functionality with reduced power requirements.
3Duration of action of stationary object
If the information processing apparatus operates in pass-through mode to maintain communication continuity, then communication continuity is improved, but security protection deteriorates
Solution Approach 1:
The system dynamically selects between normal mode (full security processing) and pass-through mode (no decryption) based on power supply conditions. When power is sufficient, it operates in normal mode for maximum security. When power fails or is severely constrained, it switches to pass-through mode to maintain communication continuity, accepting reduced security protection as a trade-off for maintaining connectivity.
Solution Approach 2:
The patent converts the harmful effect of power failure into a beneficial mode switch to pass-through mode. Rather than completely failing when power is insufficient for security processing, the system uses the power constraint as a trigger to switch to a mode that prioritizes continuity over maximum security, turning the limitation into a functional advantage for maintaining communication.
4Reliability
If the information processing apparatus performs complete decryption to ensure security, then security protection is improved, but power consumption increases
Solution Approach 1:
The control unit dynamically adjusts the level of security processing based on available power supply. When power is abundant, it performs complete decryption for maximum security protection. When power becomes constrained, it reduces the scope of decryption operations or switches to pass-through mode, thereby reducing power consumption while maintaining acceptable security levels for the given conditions.
Solution Approach 2:
The system performs partial decryption or reduced security processing when power is constrained, rather than attempting complete decryption. This partial action approach maintains sufficient security protection for the available power while avoiding the excessive power consumption that would result from full decryption operations under constrained power conditions.

AI summary
According to an embodiment, an information processing apparatus comprises a device interface, a network interface, a power supply part, a battery and a control part. A power supply part is configured to supply electric power from an external power supply. A control part is configured to: perform a conversion process on data from a terminal device, and transmit the data to a network; and when the power supply from the power supply part is stopped, transmit, to another information processing apparatus through the network interface, a first message indicating that a pass-through mode in which data is relayed between the terminal device and the network without being subjected to the conversion process is set, and set the pass-through mode.
