Quantum threats refer to the potential security risks posed by advanced quantum computing to current cryptographic systems. Specifically, large-scale quantum computers could theoretically break widely used public-key encryption algorithms, such as RSA and ECC, which secure digital communications and blockchain transactions. This could compromise the confidentiality and integrity of digital assets and decentralized networks. The development of quantum-resistant cryptography is a critical countermeasure against these risks.
Context
The current discussion around quantum threats focuses on the urgent need for cryptographic migration strategies to post-quantum algorithms. A key debate involves the timeline for quantum computer development and the readiness of existing systems to adapt. Future developments will likely involve the standardization and deployment of new cryptographic primitives designed to withstand quantum attacks.
This novel quantum-enhanced Proof-of-Vote protocol integrates quantum signatures and entangled states to establish the first post-quantum security model for permissioned decentralized ledgers.
