Secure Data Transmission using Cryptography for Internet of Things and Sensor Networks Applications

Recent years have seen tremendous advancements in human life thanks to IoT, which can be seen in healthcare applications as well as regular duties. Everyday items may now be linked to the web thanks to the IoT. Data collection and dissemination are key functions for these devices, thus they include sensors and actuators. However, there may be various privacy and security issues throughout the data’s transfer. In order to address this issue, we present a Secure Data Transmission Scheme (SDTS) that enhances the security of communications in WSNs that are organised into clusters (WSNs). Elliptic Curve Cryptography (ECC) is the foundation of the SDTS because it provides a high degree of security with a very small key size. Several security goals, such as privacy, integrity, and authentication, are addressed by the suggested approach. Not only that, but it’s secure against a wide variety of threats, including brute force assaults, replay attacks, and sinkhole attacks. The results of the performance study demonstrate that SDTS is cost-effective in its communications.
