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，必须在用户之间处理，存储和交换大量数据，这使数据完整性和信息安全非常重要。为了保护数据并使其安全，正在将各种加密原始词纳入许多标准和协议中，并在各种平台中实施；从用于服务器和基站的强大计算机到无线设备中使用的轻质密码系统。密码系统的性能在很大程度上依赖于有效的加密计算，特别是在资源约束的嵌入式系统中，例如智能卡，RFID标签，物联网和无线传感器网络中的节点，在该系统中，功耗，内存和带宽非常有限。由于其复杂的性质，可靠，高效的设计和加密计算的实施具有挑战性。该研究的主要目标总结如下：***（i）我们将研究用于有限领域算术操作的新的有效算法和体系结构的开发，例如使用多项式，多项性的多项式和高斯正常基础代表来使用乘法，平方，平方，反转和二进制扩展领域的凸起。我们将考虑他们在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，以实现轻质和高性能应用程序，以具有低资源和/或高速计算。***（ii）我们将根据我们新提出的拟议的多重毕业者研究许多公共和私钥密钥系统的设计和实现。有限场乘法是基于椭圆曲线和基于指数的密码系统，AES-GCM身份验证的加密和WG流密码中的主要算术操作。使用不同数字级乘数的效果将被研究以进一步优化两端应用程序的这些密码系统，即轻巧和高性能加密系统。 ***（iii）我们将为私人和公共密钥加密系统探索新的可靠和强大计划，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严重关注。该研究将基于采用高开销和可接受的错误检测能力的有效并发错误控制编码方法。 ****这项研究将导致更安全和可靠的密码系统的成本较低和性能更高。它还将为培训学术界和大量加拿大信息和通信技术（ICT）领域的大量公司培训高素质的人员做出重大贡献。**
