噪音安全互联网
Noise Secured Internet
摘要:
这项工作显示了如何通过一个快速的密钥分配系统,使用物理噪声来保护传输的信息,可以实现一个安全的互联网。从两个(或多个)用户之间的共享随机序列$K_0$开始,可以共享随机比特的长序列$R$。通过互联网发送的信号是确定性的,但有一个内置的自然制造的不确定性,保护共享序列。在保密放大之后,共享的$R$随机比特--由噪声加密--随后被用于一次一密数据加密。
英文摘要:
This work shows how a secure Internet can be implemented through a fast key distribution system that uses physical noise to protect the transmitted information. Starting from a shared random sequence $K_0$ between two (or more) users, longsequences $R$ of random bits can be shared. The signals sent over the Internet are deterministic but have a built-in Nature-made uncertainty that protects the shared sequences. After privacy amplification the shared $R$ random bits --encrypted by noise-- are subsequently utilized in one-time-pad data ciphering.
