==MONITORING SYSTEM FOR MONITORING HASH-BASED DIGITAL SIGNATURES - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18282900 titled 'MONITORING SYSTEM FOR MONITORING HASH-BASED DIGITAL SIGNATURES

==Simplified Explanation==

The monitoring system described in the abstract is designed to receive signature requests, store data, generate digital signatures, extract one-time signatures, compare public keys, and provide warnings if necessary. 

* Requesting device, monitoring apparatus, and signing device are components of the system
* Monitoring apparatus receives signature request data and digital signatures
* One-time public keys are determined and compared to previous keys
* If a new key is detected, it is stored; if a repeat key is found, a warning signal is sent

== Potential Applications ==
This technology could be applied in secure document signing, authentication processes, and data integrity verification.

== Problems Solved ==
This system helps prevent unauthorized access, ensures data integrity, and enhances security measures for digital signatures.

== Benefits ==
The system provides a reliable way to verify signatures, detect unauthorized changes, and maintain secure communication channels.

== Potential Commercial Applications ==
This technology could be utilized in industries such as finance, healthcare, legal services, and government agencies for secure document handling and authentication processes.

== Possible Prior Art ==
One possible prior art could be traditional digital signature systems that rely on public-private key pairs for authentication and data integrity verification.

=== What is the specific cryptographic function used for generating digital signatures in this system? ===
The abstract mentions a stateful hash-based cryptographic function, but it does not specify the exact algorithm or method used for this purpose.

=== How does the system handle potential conflicts or discrepancies in the received signatures? ===
The abstract mentions that if a one-time public key is equal to a previous key, a warning signal is sent to the requesting device. However, it does not elaborate on how the system resolves or addresses these conflicts.


==Original Abstract Submitted==

A monitoring system including a requesting device, a monitoring apparatus and a signing device, wherein the monitoring apparatus is configured to receive a signature request data structure, store the data, receive a hash-based digital signature generated for the data by a stateful hash-based cryptographic function of the signing device, extract a one-time signature from the received hash-based digital signature, determine a one-time public key based on the stored data to be signed and the one-time signature, compare the one-time public key with previous one-time public keys determined from hash-based digital signatures previously received from the signing device, and if the one-time public key is different to any of previous one-time public keys, store the one-time public key in a data storage unit, if the one-time public key is equal to at least one of the previous one-time public keys, output a first warning signal to the requesting device.
