The student will develop new techniques for lattice-based cryptography with application to privacy-preserving signatureschemes. In particular, lattice-based group and ring signature schemes typically rely on strong assumptions in theirsecurity proofs to allow for more efficient constructions, however, these strong assumptions do not accurately model realworld behaviour leaving the resulting primitives open to vulnerabilities. The project will propose new group and ringsignatures that bypass the need for unrealistic models, whilst maintaining usable efficiency and functionality. To achievethis, the student will need to explore novel proof techniques that can be applied to the aforementioned primitives.&

学生将开发基于格的密码学新技术，并将其应用于隐私保护签名方案。特别是，基于格的群签名和环签名方案通常依赖于安全证明中的强假设来实现更有效的构造，但是，这些强假设并不能准确地模拟现实世界的行为，从而导致生成的原语容易受到攻击。该项目将提出新的组签名和环签名，从而绕过对不切实际的模型的需求，同时保持可用的效率和功能。为了实现这一目标，学生将需要探索可应用于上述原语的新颖证明技术。
