Secure Data In LoRaWAN Network By Adaptive Method Of Elliptic-curve Cryptography

Today, many new technologies have emerged data transmission in high secrecy over a long distance without using the Internet. Perhaps the most prominent of these technologies is LoRaWAN (Long Range Wide Area Network) depended on LoRa Technology (short for long range) for transmitting data. LoRa Technology is a long range (about 21 kilometers), low power wireless platform that has become the de facto technology for the Internet of Things (IoT). LoRa modulation is able to extract data from a weak signal in several environments (urban and rural). In order to make use of the network of LoRaWAN and modern technology LoRa, it is will be applied in a practical manner in this paper. In spite of the advantages of this technology of the long-range connection, low energy, and security which is based on Advanced Encryption Standard (AES)128-bit for data encryption, however, the many recent studies confirm to have a security vulnerability in this technology, could develop to an attack called” bit-flipping attack”. Therefore, this paper suggests an immunization during moving data across this network. This is will be done by adding an extra layer of encryption via a proposed adaptive method including elliptic curve cryptography technology and a digital signature.
