随着近年来物联网（IoT）设备数量的激增，这些设备的安全性已成为地球仪的主要关注领域。加密是保护物联网设备中数据的重要手段，但加密实现也容易受到攻击。这些漏洞可以让攻击者完全绕过或显著削弱加密算法的理论强度。仅仅抵抗密码分析是不足以在实践中建立一个安全的密码系统。功率分析侧信道攻击已经成为通过监视设备的功耗来发现加密密钥的非常有效的方法。芯片的功耗可以揭示有关正在执行的加密操作或正在处理的数据的信息。在文献中已经讨论了许多针对功率分析攻击的对策。然而，所有这些对策都引入了各种权衡，诸如增加的功耗、降低的性能以及增加的额外硬件的空间要求。除了对功耗分析攻击的强大抵抗力和实现的简单性之外，开发人员还需要在设计和实现物联网时考虑这些权衡来评估对策，物联网通常在异构和高度资源约束的环境中运行。本文探讨了最先进的功耗分析攻击及其对策，并根据物联网设备中存在的限制分析了这些对策的局限性。
With the explosion in the number of internet of things (IoT) devices in recent years, the security of these devices has become an area of major concerns across the globe. Encryption is an essential means of protecting data in IoT devices, but cryptographic implementations are vulnerable to attacks as well. These vulnerabilities can allow attackers to completely bypass or significantly weaken the theoretical strength of the encryption algorithms. Resistance to cryptanalysis alone is not adequate for building a secure cryptosystem in practice. Power analysis side-channel attacks have emerged as a very effective method of discovering cryptographic keys by monitoring the power consumption of devices. Power consumption of the chips can reveal information about the cryptographic operations being performed or the data being processed. Numerous countermeasures against power analysis attacks have been discussed in the literature. However, all these countermeasures introduce various tradeoffs, such as increased power consumption, decreased performance, and increased space requirements for additional hardware. In addition to strong resistance to power analysis attacks and simplicity of implementation, developers need to evaluate the countermeasures by taking into consideration these tradeoffs while designing and implementing the IoT, which are often operated in heterogenous and highly resource constraint environments. This paper explores the state-of-the art power analysis attacks and their countermeasures and analyze the limitations of these countermeasures based on the constraints present in IoT devices.
