Analysis of Quantum Key Distribution based Satellite Communication

Vishal Sharma, Subhashish Banerjee

摘要:

量子密钥分发是一种有效的加密技术,可用于在卫星和地面站之间进行安全的量子通信。量子密码学增强了诸如光纤和无线网络的各种网络中的安全性。除此之外,由于大气效应和噪声,这些网络在存在高衰减的情况下变得脆弱。因此,由于退相干而发生误差。噪声量子信道的建模和实现的冗余的量子纠错方案,提供了更好的安全性和吞吐量效率,从仿真结果中所示。

英文摘要:

Quantum key distribution is an effective encryption technique which can be used to perform secure quantum communication between satellite and ground stations. Quantum cryptography enhances security in various networks such as optical fibers and wireless networks. In addition to this, these networks become vulnerable in presence of high attenuation due to atmospheric effects and noise. Hence, errors occur due to decoherence. The noisy quantum channel is modeled and implemented by the redundancy-free quantum error correction scheme which provides better security and throughput efficiency as shown in simulation results.
