==QUANTUM KEY DISTRIBUTION-BASED QUANTUM DIGITAL SIGNATURE METHOD AND SYSTEM INCLUDING TRUSTED NODE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240235825 titled 'QUANTUM KEY DISTRIBUTION-BASED QUANTUM DIGITAL SIGNATURE METHOD AND SYSTEM INCLUDING TRUSTED NODE

The present disclosure describes a quantum key distribution (QKD)-based quantum digital signature method using a trusted node, where the method involves sharing secret keys with message-sending and message-receiving nodes, generating trusted-node signatures through partial QKD processes, and verifying messages using the shared secret keys and trusted-node signatures.

* Quantum key distribution (QKD) is used to create secure digital signatures.
* Trusted nodes are utilized to facilitate the QKD-based quantum digital signature method.
* Secret keys are shared between nodes for secure communication.
* Trusted-node signatures are generated through partial QKD processes.
* Messages are verified using the shared secret keys and trusted-node signatures.

Potential Applications:
- Secure communication in sensitive industries such as finance and healthcare.
- Enhancing data security in government communications.
- Securing online transactions and digital signatures.

Problems Solved:
- Mitigating the risk of unauthorized access to sensitive information.
- Preventing data breaches and cyber attacks.
- Ensuring the integrity and authenticity of digital signatures.

Benefits:
- Enhanced security and privacy in communication.
- Protection against cyber threats and data breaches.
- Reliable verification of digital signatures.

Commercial Applications:
Title: Quantum Digital Signature Technology for Secure Communication

==Original Abstract Submitted==

the present disclosure according to at least one embodiment provides a quantum key distribution (qkd)-based quantum digital signature method using a trusted node, the qkd-based quantum digital signature method being performed by a trusted node. the method comprises sharing a first secret key with a message-sending node, sharing a second secret key with a message-receiving node, generating a first trusted-node signature by performing a partial qkd process together with the message-sending node, generating a second trusted-node signature by performing a partial qkd process together with the message-receiving node, and verifying a first message with the shared first and second secret keys and with the first and second trusted-node signatures.
