摘要
数据保密性和资源有限性问题是物联网面临的挑战。为了在物联网系统上实现良好的安全性,密码学可以做到这一点,但它需要一种不需要大量资源的有效加密算法。本研究的目的是通过实施一种成功维护传输数据机密性的算法来保护物联网系统。本研究采用实验方法,通过创建农业物联网系统并添加加密算法。物联网系统使用NodeMCU作为微控制器。NodeMCU是一种资源较少的微控制器,因此需要一种高效的算法来实现。在桌面计算环境中性能较好的一种算法是高级加密标准AES (advanced Encryption Standard)算法。该算法在使用REST (Representational State Transfer) web服务的数据交换架构的物联网计算环境中进行了测试,从而产生了一个具有加密实现的农业物联网系统。在进行的测试中,128位和256位明文的加密过程分别耗时266.31微秒和274.31微秒,所使用的内存分别占总内存的16%和17%。这表明加密时间很快,并且内存使用相对较小。
Pengamanan Internet of Things Berbasis NodeMCU Menggunakan Algoritma AES Pada Arsitektur Web Service REST
Data confidentiality and resource's limitation issues are challenges for the Internet of Things. To implement good security on IoT systems, cryptography can do it, but it needs an effective encryption algorithm that does not require a lot of resources. The purpose of this study is to secure an IoT system by implementing an algorithm that is successful in maintaining the confidentiality of data transmitted. This research uses an experimental approach, by creating an IoT system for agriculture and adding an encryption algorithm. The IoT system uses NodeMCU as a microcontroller. NodeMCU is a microcontroller with small resources so it needs an efficient algorithm to be implemented in it. One algorithm that has good performance in a desktop computing environment is the Advance Encryption Standard (AES) algorithm. The algorithm is tested in an IoT computing environment with a data exchange architecture using an REST (Representational State Transfer) web service, resulting in an IoT system for agriculture with cryptographic implementations in it. In the tests carried out, the encryption process of 128 and 256 bits of plain text took 266.31 and 274.31 microseconds, while the memory used was 16% and 17% of the total memory, respectively. This shows the encryption time is fast, and the memory usage is relatively small.
