基于量子密码与保密通信研究

随着信息网络技术的快速发展,大量的信息需要通过网络传输,传统的保密通信系统面临着新的挑战。量子计算机可以轻易地破译以往认为非常难以破译的加密算法,发展新的加密技术极其重要。量子密码学建立在量子力学的基础上,用量子状态作为信息加密和解密的密钥,是一种全新的保密通信系统。与建立在复杂数学计算基础上的传统加密算法相比,量子密码技术在理论上是绝对安全的,在信息交流日趋频繁的今天具有广阔的应用前景。

Secure communication research based on quantum cryptography

With the fast development of information network technology,more and more information is transmitted through the network.The conventional secure communication system faces a new challenge to protect the transmitted information and data.It is easy for a quantum computer to decrypt the traditional keys;therefore it is very important to develop the new ciphering technology.The quantum cryptography based on the quantum mechanics,which uses the quantum states as the key for encryption and decryption,is a completely new secure communication system.Different with the conventional cryptography which is based on the complex mathematical computing,the quantum cryptography is absolutely secure in theory,having the wide application in modern communication systems.
