==PUF AND BLOCKCHAIN BASED IOT EVENT RECORDER AND METHOD - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240235857 titled 'PUF AND BLOCKCHAIN BASED IOT EVENT RECORDER AND METHOD

The patent application describes a device with a physically unclonable function (PUF) module and outer layer components that create an unsecured channel for inputting challenges and receiving responses. The PUF module includes internal logic that automatically logs challenges and responses in a log medium, such as a blockchain.

* Physically unclonable function (PUF) module for secure challenge-response interactions
* Outer layer components providing an unsecured channel for inputting challenges and receiving responses
* Internal logic with a logging mechanism to record challenges and responses in a blockchain
* Method for sending messages to be recorded on a blockchain and verifying their authenticity before sending additional messages
* Potential use of the device and method for secure authentication, data encryption, and secure communication protocols

**Potential Applications:**
The technology can be applied in secure authentication systems, data encryption protocols, and secure communication channels.

**Problems Solved:**
The technology addresses the need for secure and tamper-proof logging of challenges and responses in authentication systems.

**Benefits:**
Enhanced security and tamper-proof logging of authentication interactions, improved data encryption protocols, and secure communication channels.

**Commercial Applications:**
The technology can be utilized in industries requiring secure authentication systems, data encryption protocols, and secure communication channels, such as banking, healthcare, and government sectors.

**Questions about the Technology:**
1. How does the logging mechanism in the PUF module ensure the authenticity of challenges and responses?
2. What are the potential implications of using blockchain technology for secure authentication systems?


==Original Abstract Submitted==

according to a first aspect disclosed herein there is provide a device comprising: a puf module, and one or more outer layer components providing at least part of an unsecured channel for inputting a challenge to the puf module and receiving back a response. internal logic of the puf module comprises a logging mechanism arranged to automatically log a record of the challenge and/or response in a log medium, e.g. a blockchain. according to a second aspect, there is provided a method comprising: sending a first message to be recorded on a blockchain, submitting a query to check that the first message has been recorded on the blockchain without manipulation, on condition thereof, sending a second messaging transaction to be recorded on the blockchain. the first and second aspects may be used together or independently.
