Securing Hackable IoT Enabled LTE Devices

Abstract

In this modern era of Global World, the importance of Internet and Telecommunication increases a lot. Everyday business deals, diplomatic relations, health monitoring devices, weather stations, smart home appliances, goods monitoring appliances and so on, all are using Internet services. We are living in the world where intruders might be present. They can get access to our network and monitor our communication. So, confidentiality and integrity of data might be lost. Currently, Wi-Fi communication is very much secured as compared to GSM/LTE, but this is not moveable. Wi-Fi communication has some limitations, it can’t be used in mobile devices i.e. weather stations, transport and etc. LTE communication is secured but the link between sender and receiver is not secure. We are making an IoT device which will be secure and provide authentication as well. This device will use LTE SIM-7000E module, Wi-Fi ESP-8266 module, Temperature sensor BMP-280, Arduino, Google Sheets, PCB and AES-128-bit encryption. BMP-280 sensor will measure the temperature and send it to Google Sheets, where AES-128-bit encryption will be applied. After this data will be sent to cloud services (Google Drive) using LTE communication and end user can monitor it on the Android App. As the data is encrypted, hacker/intruder can’t view the data in the form of plain text. Even if the cloud services get compromised your data will remain secure. In this way you can monitor your data anywhere in the world without worrying about security and privacy.
