INTRODUCTION
Satellite encryption is used in transferring and communicating data in our house television or mobile phone.
Satellite communication has begun to face competition from optical fibre systems for point to point communication between large concentrated traffic sources .
When we communicate via satellites there is a possibility that an interceptor can interfere and read the message being sent. To prevent this and to send the information in a secure manner we use satellite encryption
SATELLITE ENCRYPTION
The term encryption is also known as scrambling. A system that takes the signal and reconfigures it into something that is unusable without a corresponding decoder. Encryption means secret writing. It is used to hide information and access by unauthorized parties especially during communication in military and national affairs.
