Dear Vignesh,

welcome,

I want to introduce here some opinion how to include encryption and source coding in your system. As for source coding you may use lossless source coding algorithm such as variable length coding or arithmetic context adaptive variable length coding or nay other suitable algorithm.

As for the encryption you can use advanced encryption algorithm AES, as an encryption standard.

All these algorithms are available as a source code, that you can get them by searching the web.

Best wishes
