A Quantum Public Key Cryptographic Scheme Using Entangled States and Grover Operator

연구 분야: Cryptography

학회: International Conference on Security and Privacy

Quantum cryptography is used to enhance data security measures through the use of quantum mechanics. Our proposed Quantum Public Key Cryptographic (QPKC) system employs entangled states and the Grover operator to repel against any form of quantum attacks including Shor’s algorithms that are aimed at breaking some classical cryptosystems. In terms of key generation, we design the basis on entangled states to assure privacy-protected relationships between these keys and instant notifications on data snooping efforts by eavesdropping. This strategy gets rid of the weaknesses of tensor product-based systems while ensuring proper security. On the other hand, Grover operator increases efficiency in encrypting and decrypting data by making use of the quantum search feature hence much better compared to the classical methods. Our method employs the inherent advantages of entanglement - enhanced key correlations and dependable eavesdropping detection. By eliminating both classical and quantum threats, this approach strengthens cryptographic protocols, ensuring security against advanced attacks.
