隐私的终极物理极限 The ultimate physical limits of privacy

论文摘要 

你能防止秘密不被偷听吗?是的,你能, Artur Ekert 和 Renato Renner说。他们认为,量子加密领域的最新进展、再加上我们仍然具有意志自由的事实表明,真正私密的通信始终都将是可能的,即便是在一个能够获得迄今尚未发现的密码破解技术的世界中。答案在于对随机性和非局部相关性之性质的新认识。因此,如果具备了这种知识,就应当有可能智胜即便是最为强大的监测程序。

Abstract 

Among those who make a living from the science of secrecy, worry and paranoia are just signs of professionalism. Can we protect our secrets against those who wield superior technological powers? Can we trust those who provide us with tools for protection? Can we even trust ourselves, our own freedom of choice? Recent developments in quantum cryptography show that some of these questions can be addressed and discussed in precise and operational terms, suggesting that privacy is indeed possible under surprisingly weak assumptions.
