Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying unique equipment in IoT networks, such as IP addresses and MAC addresses, are easily replicable, and reliance on external certificate authorities for data authentication and time stamping is insecure, especially with the limitations of IPv6 and potential key decipherment risks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If software-based identification methods (IP address, MAC address) are used, then equipment identification is simple and easy to implement, but the identification can be easily copied and uniqueness cannot be guaranteed
Solution Approach 1:
The patent replaces software-based identification systems with a physical system based on radioactive decay. A radioactive substance is sealed in a container with a detection device that counts decay events, generating identification data based on physical rather than software mechanisms. This substitution ensures uniqueness because the physical decay process cannot be replicated, solving the contradiction between ease of implementation and reliability of uniqueness.
2Reliability
If external certificate authorities are used for data authentication, then data authenticity can be verified, but security risks increase due to potential key decipherment and system vulnerabilities
Solution Approach 1:
The patent extracts the authentication function from external certificate authorities and implements it locally within each device. Each device generates its own identification data based on radioactive decay and uses this for self-authentication. This extraction eliminates dependency on external authorities and their associated security risks, while maintaining authentication capability through local physical processes.
Solution Approach 2:
Each device performs its own authentication using identification data generated from its internal radioactive decay process. The device independently verifies its own uniqueness and authenticity without needing external certificate authorities. This self-service approach removes security vulnerabilities associated with external systems while maintaining reliable authentication.
3Quantity of substance
If IPv6 addressing is used to manage increasing equipment numbers, then more devices can be connected, but worldwide rules are not completely in effect and duplicate numbers may occur
Solution Approach 1:
The patent replaces the IPv6 numerical addressing system with a physical identification system based on radioactive decay counting. Instead of relying on software-based address allocation that may have duplicates, each device uses a sealed radioactive substance whose decay events are physically counted and converted to identification data. This physical mechanism guarantees uniqueness even as the number of connected devices increases to trillions, solving the contradiction between quantity and reliability.

Function Achieved in This Case
This approach ensures that connected equipment is uniquely identified and cannot be copied, and digital data can be authenticated autonomously, preventing tampering and ensuring genuine data transmission without reliance on external authorities.
Implementation Method 1
an emitter, which includes a radioisotope containing a number of atoms greater than a total number of identification targets; and a detector, which is configured to detect an α particle, a β ray, and/or a γ ray emitted from the emitter due to spontaneous decay of an atomic nucleus
Data Source
AI summary
Provided is an apparatus including a pulse generation device and a memory. The pulse generation device includes: an emitter, which includes a radioisotope containing a number of atoms greater than a total number of identification targets; and a detector, which is configured to detect an α particle and others emitted from the emitter due to spontaneous decay of an atomic nucleus to generate electric pulses. The memory stores a number of electric pulses obtained by measuring, in advance, for a given period of time, the electric pulses that are generated in the pulse generation device (initial pulse count), a date of the measurement, and an identification numerical value obtained by digitizing a pulse interval between the electric pulses (initial identification numerical value).
