Lightweight cryptography refers to the design and implementation of security algorithms that are targeted to digital hardware embedded systems constrained in resources, such as area, power, and energy. Examples of such systems include RFID tags, smartcards, and nodes in wireless sensor networks and the constrained nature of such systems poses unique challenges for the design of system security. The intent of this research is to investigate the design, implementation, and application of lightweight cryptographic algorithms such as block ciphers, stream ciphers, and hash functions targeted to embedded systems. In this research, we will explore the design and implementation issues of lightweight cryptography, targeted to both application specific integrated circuits (ASICs) and field programmable gate arrays (FPGAs), and will include consideration of all requirements important to embedded systems, including area, power, and energy. Since many embedded systems can be expected to utilize multiple cryptographic algorithms, we will examine aspects such as resource sharing to improve efficiency. Further, the designs and implementations will consider the application of side-channel attacks and methods will be investigated to mitigate these attacks. Research outcomes will include the creation of new lightweight cipher and hash algorithms, analysis of new and existing algorithms, and the development of novel, efficient implementations targeted to important applications such as wireless sensor networks. The research undertaken will contribute significantly to the knowledge associated with lightweight cryptographic hardware design and is expected to influence the engineering practice associated with embedded system security. This will be of significant value, both in terms of intellectual property and training of highly qualified personnel, to Canadian industry and government organizations in the information technology and telecommunications sectors.

轻量级密码学是指设计和实现的安全算法，针对数字硬件嵌入式系统的资源有限，如面积，功率和能源。这样的系统的例子包括RFID标签，智能卡，和无线传感器网络中的节点，这样的系统的约束性质提出了独特的挑战，系统安全的设计。本研究的目的是探讨轻量级密码算法的设计，实现和应用，如分组密码，流密码，和哈希函数针对嵌入式系统。 在这项研究中，我们将探讨轻量级密码学的设计和实现问题，针对专用集成电路（ASIC）和现场可编程门阵列（FPGA），并将包括对嵌入式系统重要的所有要求的考虑，包括面积，功率和能源。由于许多嵌入式系统可以预期利用多种加密算法，我们将研究资源共享等方面，以提高效率。此外，设计和实现将考虑侧信道攻击的应用，并将研究减轻这些攻击的方法。 研究成果将包括创建新的轻量级密码和哈希算法、分析新的和现有的算法，以及开发针对无线传感器网络等重要应用的新颖、高效的实现。所进行的研究将有助于显着的知识与轻量级密码硬件设计，并预计将影响与嵌入式系统安全相关的工程实践。这对加拿大信息技术和电信部门的工业和政府组织在知识产权和培训高素质人员方面都具有重大价值。
