虽然量子计算机为我们带来了史无前例的计算和数据分析能力，但据荷兰埃因霍温理工大学的一项研究称，它们也会给现在的网络安全和隐私带来巨大风险。这项最新研究称，量子计算机的全面崛起预计将出现在2025年左右，这就需要技术人员快速研发出全新的密码技术。</div><div><br></div><div> 这份警告是荷兰埃因霍温理工大学的Tanja Lange博士和美国伊利诺伊大学的Daniel J. Bernstein共同发出的。</div><div><br></div><div><p style="text-align: center;"><a href="data/attachment/portal/201709/27/094210uio1v3hhitzj3111.jpg" target="_blank"><img

量子计算机是建立在量子力学的基础上。这意味着这些强大的机器能够快速解决许多问题。比如说为农民提供准确气候播报，研发新药物等，但是在金融领域的应用可能存在一些问题。研究人员担忧，量子计算机的先进而强大的能力能够破解几乎所有的代码和安全设定。然而最令人担忧的是用于整体分解的秀尔演算法，这种算法能够破解目前全世界使用的所有密码技术。</div><div><br></div><div><p

Adleman在1977年发明的，这种算法是公共安全所使用的一种密码算法。</div><div><br></div><div> 椭圆曲线加密法是最新发明的，它能够提供更强的安全性，并且缩短密码长度。这些密码用在目前的计算机上几乎是无法破解的，但是研究人员认为量子计算机能够在短短的几小时内破解这两种安全密码。</div><div><br></div><div> Tanja Lange认为，这会给数据安全带来威胁，比如说私人数据、银行和健康记录以及国家秘密等。密码编译者面临着巨大的压力，他们需要发明新的东西，而且是量子计算机都难以破解的。虽然这个过程很慢，但是她认为很快我们就会看到后量子安全策略的崛起，而且NASA和许多公司都有这种需求。Lange目前正与11位大学的同行们合作，探索新的安全解决方案。这个项目也获得了欧洲委员会390万欧元的资金支持。</div><div><br></div><div><p
