Implementation aspects of lattice-based cryptography on hard ware

基于格的密码学在通信中提供了广泛的适用性、计算效率以及强的后量子安全性和前向保密性。本博士项目将研究基于格的密码学在硬件和软件平台上的实现问题。近年来，新的基于格的密码学方案被提出用于密钥交换、公钥加密、数字签名、同态加密、函数加密等。这些新方案的有效实施将是具有挑战性的，非常有趣的，因为它需要调整加密方案的数学步骤，高效算法的设计，硬件架构设计和平台特定的优化。这个学生的主要目标是为基于格的密码学开发优化和侧通道保护算法，并在硬件和软件平台上实现它们。

Lattice-based cryptography offers wide applicability, computational efficiency, and strong post-quantum security and forward secrecy in communications. This PhD project will investigate implementation aspects of lattice-based cryptography on hardware and software platforms.In the recent years, new lattice-based cryptographic schemes for key exchange, public-key encryption, digital signature, homomorphic encryption, functional encryption etc. have been proposed. Efficientimplementation of these new schemes will be challenging and very interesting as it would require tweaking the mathematical steps ofthe cryptographic schemes, design of efficient algorithms, hardwarearchitecture design and platform-specific optimization.The main goal of this studentship will be to develop optimised and side-channel protected algorithms for lattice-based cryptography and implement them on hardware and software platforms.
