With rapid advances in information, computer and communication technologies and systems, huge amount of data has to be processed, stored and exchanged among users, which makes data integrity and information security very important issues. To protect the data and make it secure, various cryptographic primitives are being incorporated in many standards and protocols and implemented in a wide range of platforms; from powerful computers used in servers and base stations to lightweight cryptosystems used in wireless devices. The performance of cryptosystems rely heavily on efficient cryptographic computations, specially in resource constrained embedded systems, such as smart cards, RFID tags, Internet of Things, and nodes in wireless sensor networks, where the power consumption, memory, and bandwidth are very limited. Reliable and efficient design and implementation of cryptographic computations are challenging due to their complex nature. The main objectives of the research are summarized as follows:***(i) We will investigate the development of new efficient algorithms and architectures for finite field arithmetic operations, such as multiplication, squaring, inversion, and exponentiation in binary extension fields using polynomial, shifted polynomial and Gaussian normal basis representations. We will consider their designs and implementations in ASICs and FPGAs. For each and every working platform, we plan to further optimize these operations for both lightweight and high-performance applications to have low-resource and/or high-speed computations.***(ii) We will study the designs and implementations of a number of public and private key cryptosystems based on our newly proposed multipliers. Finite field multiplication is the main arithmetic operation used in elliptic curve and exponentiation-based cryptosystems, the AES-GCM authenticated encryption and the WG stream cipher. The effects of using different digit-level multipliers will be investigated to further optimize these cryptosystems for two-end applications namely, lightweight and high-performance cryptosystems. ***(iii) We will explore new reliable and robust schemes for private and public key cryptosystems to counteract natural faults and fault attacks. This research is very important due to the fact that fault attacks have become a serious concern in cryptographic applications. The research will be based on adopting efficient concurrent error control coding approaches with low overhead and acceptable error detection capability. ****This research will lead to more secure and reliable cryptosystems with lower cost and higher performance. It will also significantly contribute to training highly qualified personnel for academia and a large number of companies in the Canadian Information and Communications Technologies (ICT) sector.**

随着信息、计算机和通信技术和系统的快速进步，用户之间需要处理、存储和交换大量数据，这使得数据完整性和信息安全变得非常重要。为了保护数据并确保其安全，各种加密原语被纳入许多标准和协议中，并在各种平台上实施；从服务器和基站中使用的强大计算机到无线设备中使用的轻量级加密系统。密码系统的性能在很大程度上依赖于高效的密码计算，特别是在资源受限的嵌入式系统中，例如智能卡、RFID标签、物联网和无线传感器网络中的节点，这些系统的功耗、内存和带宽都非常有限。由于其复杂性，可靠且高效的密码计算设计和实现具有挑战性。研究的主要目标概述如下：***（i）我们将研究有限域算术运算的新有效算法和架构的开发，例如使用多项式、移位多项式和高斯正则基表示在二进制扩展域中进行乘法、平方、求逆和求幂。我们将考虑它们在 ASIC 和 FPGA 中的设计和实现。对于每个工作平台，我们计划进一步优化这些操作，以实现轻量级和高性能应用程序，以实现低资源和/或高速计算。***（ii）我们将研究基于我们新提出的乘法器的许多公钥和私钥密码系统的设计和实现。有限域乘法是椭圆曲线和基于幂的密码系统、AES-GCM 认证加密和 WG 流密码中使用的主要算术运算。将研究使用不同数字级乘法器的效果，以进一步优化这些密码系统的两端应用，即轻量级和高性能密码系统。 ***(iii) 我们将为私钥和公钥密码系统探索新的可靠且稳健的方案，以抵消自然故障和故障攻击。这项研究非常重要，因为故障攻击已成为密码应用中的一个严重问题。该研究将基于采用具有低开销和可接受的错误检测能力的高效并发错误控制编码方法。 ****这项研究将带来更安全、更可靠、成本更低、性能更高的密码系统。它还将为加拿大信息和通信技术 (ICT) 领域的学术界和大量公司培训高素质人才做出重大贡献。**
