Abstract

The safe transmission of sensitive data, including credit card numbers, is a major issue in the current digital era. Quantum encryption methods, which use the principles of quantum physics to create safe keys, may be able to fix this problem. One of the most promising quantum encryption methods is quantum key distribution (QKD), which provides unconditional security by using the laws of quantum mechanics to identify any attempt to intercept or eavesdrop on the transmission. In this work, we examine the use of quantum encryption algorithms for the encryption and decryption of credit card data. We discuss the foundations of QKD and how it may be used to generate safe keys for credit card data encryption using industry-standard encryption methods. We also examine the real challenges and limitations associated with implementing QKD, such as the need for ...
