Satellite communication is an emerging field of communication. It is used for many applications, such as broadcasting, messaging, telephony, and for communication between military troops. The satellite communication is prone to impersonate attacks as the access to the satellite does not require a physical connection. Hence, there is a foremost need to restrict the access to only legitimate users. This study aims to solve achieve this. The proposed scheme is based on elliptic curve cryptography (ECC) and assures access to legitimate users only and also claims to be lightweight in working. The analysis indicates that the proposed technique is free from various attacks including internal and external attacks. Also, the performance analysis confirms the proposed authentication scheme as more reliable and robust against attacks compared with existing techniques.
