Satellite Communication is one of the most important parts of today's technology. There are about 2,134 satellites in Earth's orbit. Satellites are generally used for communication, whether monitoring, GPS, etc. Today the whole world depends upon the satellite for the broadcasting of data around the globe. The satellite also plays an important role in the defense sector. Specially designed satellites are used for defense purpose. Since satellite plays such an important role, security becomes the major issue. This paper deals with the Security issues faced by a satellite network and how we can solve those issues. Also, this paper mentions the method of Quantum Cryptography recently used by Chinese researchers for secure data communication.
