Abstract:

Li-Fi is the technology which supports transmission of data through light. Various techniques are used for encryption and decryption to support highly secure data transmission. In this paper, procedure for communication is used which supports secured data transmission using RC4 algorithm along with
JWSED technique at the sender’s side. JWSED is Jumbled Word String Encryption Decryption mechanism. Data is sent through Li-Fi from sender to receiver after performing its encryption. JWSED algorithm provides security while data is transmitted among Li-Fi devices. Data is input from the user. It is  encrypted using RC4 algorithm. After this, JWSED algorithm is applied which provides more security to encrypted text. Then, data is sent through the channel via Li-Fi means. On the other system at receiver side, plain data is reproduced by applying techniques for decryption i.e. reverse of techniques applied for encryption at transmitter end. Data security is primary concern in today’s world which is addressed beautifully using technique described in paper.
