Lightweight secure message transfer protocol based on Ecc in Internet of Things equipped with satellite communications

With the expansion of Internet of Things (IOT) services and the use of satellite communications, according to the regional or continental extent of these services, the need for lightweight encryption has increased. In satellite communications, due to long distances, there are limitations in applying security, so heavy encryption algorithms such as RSA cannot be trusted for security. ECC elliptic curve cryptography provides a lighter alternative by invoking a mathematical problem called the ECDLP elliptic curve discrete logarithm problem that cannot be solved in sub exponential time. Here, we propose a new strategy for secure IOT data communication between a satellite link and a terrestrial link that uses the principles of ECC elliptic curve cryptography and the NIST P-256 standard for key agreement and encryption for transmitting messages over the satellite communication platform.
