Modern cryptography has the power to revolutionise virtually every aspect of our online lives. Large-scale secure data sharing could become a breeze, with tools such as functional encryption (FE) to give us fine control over access rights by means of expressive languages, and there will be no more juggling of crypto keys. Finally, the known foundations of FE will crumble when even small-sized quantum computers become reality, perhaps next decade. This project aims to recreate and expand the power of FE from post-quantum (PQ) mathematical principles, immune to quantum attacks, building on recent discoveries of limited forms of PQ-FE from rock-solid crypto principles. It begs exploring, for the truly spectacular outcomes likely to ensue.

现代密码学有能力彻底改变我们在线生活的方方面面。大规模的安全数据共享可能会变得轻而易举，功能加密（FE）等工具可以通过表达性语言为我们提供对访问权限的精细控制，并且不会再有加密密钥的杂耍。最后，也许在下一个十年，即使是小型量子计算机成为现实，已知的量子力学基础也将崩溃。该项目旨在重建和扩展后量子（PQ）数学原理中FE的能力，免疫量子攻击，建立在最近发现的基于坚如磐石的加密原理的有限形式的PQ-FE的基础上。它需要探索，因为真正壮观的结果可能随之而来。
