在这项工作中，我们研究了著名的密码算法的适应性能量收集无线传感器网络。我们特别感兴趣的算法，有能力适应不同的权力，在这样的网络。我们的调查和硬件平台上的实现表明，这是最佳的预先计算几个关键流字节，存储在内存中，并在系统低功率水平时使用。我们的演示设置表明，使用预先计算的密钥流可以减少14%的能耗。我们已经实现了两个不同的微控制器，MSP430和AVR ATmega1281的Trivium流密码，并显示这些实现的性能结果。我们已经实现了一个基于通用哈希函数的算法，以提供流密码的协助下的消息认证。我们表明，这种认证算法具有令人兴奋的性能的能量收集系统，更一般的资源受限的设备。
In this work, we study the adaptability of well known cryptography algorithms to energy harvesting wireless sensor networks. We are particularly interested in algorithms that have the ability to adapt to varying power in such networks. Our investigations and implementation on hardware platforms indicate that it is optimal to precompute a few key stream bytes, store in memory and later used during the time when the system is low on harvested power level. Our demonstrable setup shows using a precomputed key stream can decrease the energy consumption by 14%. We have implemented the Trivium stream cipher for two different microcontrollers, the MSP430 and the AVR ATmega1281 and show the performance results for these implementations. We have implemented an algorithm based on universal hash functions to provide message authentication with the assistance of stream ciphers. We show that this authentication algorithm has exciting properties for energy harvesting system and more generally for resource constrained devices.
