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.

The SARS-CoV-2 coronavirus outbreak, or commonly abbreviated as Covid-19, is currently almost paralyzing human life in various sectors. Compared to other coronaviruses such as SARS-Cov and MERS-Cov, Covid-19 spreads very quickly in multiple countries and regions. Also, the difficulty of information obtained accurately and in real-time for the community. The role of information technology is vital for the community in monitoring the coronavirus. This research utilizes web service technology to collect data and integrate services from various sources. The protocol and web service architecture used is representational state transfer (REST), with independent data exchange using the JSON format. Web service is made with node.js as well as android applications using an android studio. The results of this study have obtained a mobile-based android application that can present covid-19 data accurately and in real-time. Data recapitulation coronaviruses distribution from four service sources that have been integrated can display globally and locally in Indonesia.

Web services are applications that allow for communication between devices over the internet and are independent of the technology. The devices are built and use standardized eXtensible Markup Language (XML) for information exchange. A client or user is able to invoke a web service by sending an XML message and then gets back and XML response message. There are a number of communication protocols for web services that use the XML format such as Web Services Flow Language (WSFL), Blocks Extensible Exchange Protocol(BEEP) etc. Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are used options for accessing web services. It is not directly comparable that SOAP is a communications protocol while REST is a set of architectural principles for data transmission. In this paper, the data size of 1KB, 2KB, 4KB, 8KB and 16KB were tested each for Audio, Video and result obtained for CRUD methods. The encryption and decryption timings in milliseconds/seconds were recorded by programming extensibility points of a WCF REST web service in the Azure cloud..

The Broker Architecture became popular involving client and server. Representational State Transfer(REST) architecture is the architecture of World Wide Web. REST uses HTTP protocol based on Servlet and ASMX technology is replaced by WCF web service technology. SOAP and REST are two kinds of WCF web services. REST is lightweight compared to SOAP and hence emerged as the popular technology for building distributed applications in the cloud. In this paper, conducted by exposing a HTTP endpoint address, HTTP relay binding (webHttpRelayBinding) and CRUD contract through interface. The interface is decorated using WebGet and WebInvoke attributes. WCF configuration file created using XML tags for use with REST web service.

Security of the Internet of Things is a crucial topic, due to the criticality of the networks and the sensitivity of exchanged data. In this paper, we target the Message Queue Telemetry Transport (MQTT) protocol used in IoT environments for communication between IoT devices. We exploit a specific weakness of MQTT which was identified during our research, allowing the client to configure the behavior of the server. In order to validate the possibility to exploit such vulnerability, we propose SlowITe, a novel low-rate denial of service attack aimed to target MQTT through low-rate techniques. We validate SlowITe against real MQTT services, considering both plain text and encrypted communications and comparing the effects of the threat when targeting different daemons. Results show that the attack is successful and it is able to exploit the identified vulnerability to lead a DoS on the victim with limited attack resources.

This paper discusses the design and prototype implementation of a software solution facilitating the interaction of third-party developers with a legacy monitoring and control system in the airfield environment. By following the Internet of Things (IoT) approach and adopting open standards and paradigms such as REpresentational State Transfer (REST) and Advanced Message Queuing Protocol (AMQP) for message dispatching, the work aims at paving the way towards a more open world in the airfield industrial sector. The paper also presents performance results achieved by extending legacy components to support IoT standards. Quantitative results not only demonstrate the feasibility of the proposed solution, but also its suitability in terms of prompt message dispatching and increased fault tolerance.

Dinas Kependudukan dan Pencatatan Sipil Kota Bogor atau lebih dikenal Disdukcapil Kota Bogor merupakan salah satu instansi pemerintahan yang berada di bidang pelayanan masyarakat yang khususnya dalam bentuk pelayanan Administrasi Kependudukan Kartu Keluarga (KK) dan Kartu Tanda Penduduk (KTP). Kondisi saat ini yang terjadi adalah belum sepenuhnya berjalan dengan baik dan masih ditemuinya hambatan. Proses pembuatan KK dan KTP saat ini dimulai dari masyarakat mengisi formulir biodata yang berada dikelurahan dan memenuhi persyaratan yang ditetapkan. Setelah semua data telah lengkap pemohon diharuskan datang ke Kantor Disdukcapil untuk memproses permohonan cetak KK dan KTP. Waktu proses pembuatan KK adalah 7 hari kerja dan untuk KTP adalah maksimal 14 hari kerja apabila tidak ada kendala dimulai dari tanggal pendaftaran. Setelah tanggal yang ditentukan pemohon datang kembali ke kantor Disdukcapil untuk mengambil produk yang mereka cetak kemarin. Pada penelitian ini memanfaatkan metode Representational State Transfer (RESTFULL) Web Service. RESTFULL web service adalah metode teknologi yang menerapkan konsep perpindahan antar state yang menggunakan browser atau disebut juga mekanisme HTTP untuk menghubungkan aplikasi dengan aplikasi lain. Dalam hal ini metode RESTFULL digunakan sebagai akses data ke Database SIAK yang bertujuan untuk mempermudah prosedur permohonan pendaftaran KK dan KTP dan memberikan informasi yang terbaharui. Berdasarkan hasil pengujian yang telah dilakukan maka dapat disimpulkan bahwa secara fungsional seluruh proses pada sistem registrasi online kependudukan dengan menggunakan metode RESTFULL Web Service telah berjalan sesuai dengan yang diharapkan dan dapat mengurangi masyarakat yang datang langsung ke kantor Disdukcapil untuk melakukan permohonan KK dan KTP serta memberikan informasi yang actual.
