能源收集系统的安全

　　能源收集系统的安全

　　安全正成为任何东西的互联网的一个重要因素，但它增加了额外的处理周期和电源。这提出了一个挑战，设计师为他们的传感器节点从环境中收获的能量。本文着眼于能源收集功率的来源，由此产生的能量预算，以及如何影响加密体系结构，从加密的节点到网关，和控制器的选择。

　　物联网的爆炸导致不同类型的传感器爆炸，但这是驱动冲突的要求，系统设计人员。一方面，这些传感器需要持续数年的电池，或根本没有电池，而另一方面，他们必须与世界其他地方沟通，并安全沟通。

　　This secure communication can be severely challenging for ultra-low-power sensor nodes. Devices that are powered by energy harvested from the environment have very little power left over for wireless communication， let alone the processing of complex encryption algorithms. However， the same factors that are driving the increasing use of such sensor nodes are also driving the need for security. While it may not seem important to secure the connection to a the valve of a radiator or water supply， the information about the use of the heating system can show whether a home is occupied or empty， making it a target for thieves. Even more important is securing remote actuators such as window locks – a vulnerability that allows a hacker to release a window or even a door at will is a major security risk.
