As the Internet of Things applications become mission-critical and their data more valuable, it becomes more and more essential to paramount their security. The security can be improved by using emerging light-weight ciphers. SIMON is a relatively recent family of light-weight ciphers which is proposed by the National Security Agency optimized for hardware platforms. In this paper, we propose an optimized hardware architecture for SIMON for high-throughput resource-constrained applications with multiple levels of security. Moreover, a configurable architecture with different operating modes is introduced for utilizing in applications requiring higher resistance to fault and power attacks. This architecture also supports an ultra-high-throughput mode for different key sizes. Implementation results of the proposed architectures on both ASIC and FPGA are reported. The comparison results show that our proposals outperform similar architectures in terms of some design metrics, e.g. throughput, which make it suitable for IoT applications. Finally, we implement practically our architecture on the Digilent-ZYBO board and report the experimental results.

随着物联网应用程序变得至关重要，并且它们的数据越来越有价值，对它们的安全性至关重要。使用新兴的轻量级密码可以提高安全性。SIMON是由国家安全局针对硬件平台进行优化的相对较轻的密码家族。在本文中，我们为SIMON提出了一种优化的硬件体系结构，用于具有多个安全级别的高吞吐量，资源受限的应用程序。此外，引入了具有不同操作模式的可配置体系结构，以用于需要更高抗故障和电源攻击能力的应用中。该体系结构还支持用于不同密钥大小的超高吞吐量模式。报告了在ASIC和FPGA上提出的体系结构的实现结果。比较结果表明，我们的建议在某些设计指标（例如吞吐量）方面优于类似的体系结构，这使其适用于物联网应用。最后，我们在Digilent-ZYBO板上实际实现了我们的架构，并报告了实验结果。
