Abstract

Cryptography is used for the secure communication in which two parties are involved. The most popular cryptographic issue is the transmission of confidential messages. The privacy is maintained using the cryptographic protocol. The security of quantum cryptography relies more on physics including quantum mechanics and statistics rather than on solving mathematical problems. A well-known application of quantum cryptography is quantum key distribution (QKD) that is used to establish communication by generating cryptographic keys. Moreover, it is based on the Heisenberg uncertainty principle that ensures the security and prevents from eavesdropping. Basically, quantum cryptography with faint laser pulses, polarization coding, phase coding, and frequency coding have been discussed.
量子密码
密码学用于涉及双方的安全通信。最常见的密码学问题是机密信息的传输。使用加密协议维护隐私。量子密码学的安全性更多地依赖于物理学,包括量子力学和统计学,而不是解决数学问题。量子密码学的一个著名应用是量子密钥分发(QKD),它通过生成加密密钥来建立通信。此外,它基于海森堡测不准原理,保证了安全性,防止了窃听。基本上,量子密码与微弱的激光脉冲,极化编码,相位编码和频率编码进行了讨论。
