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 This technology can be applied in industries such as finance, healthcare, government, and e-commerce to ensure secure and authenticated communication. The market implications include increased trust in online transactions, improved data security, and compliance with regulatory requirements.

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.
