lightweight secure message transfer protocol based on ecc (nist p-256) 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, security cannot be fully implemented given the long transmission distances, rendering heavy encryption algorithms, such as rsa, unreliable. ecc using mathematical solutions and elliptic curve discrete logarithm problems (ecdlp) can be considered a lightweight algorithm in telecommunications. 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.
