Light Fidelity to Transfer Secure Data Using Advanced Encryption Standard Algorithm

Symmetric (secret) key encryption algorithms are formally used one key for encryption and decryption processes. One of the advantages of symmetric encryption is that it provides security at a much lower cost, both in term of key size and execution time. The algorithm adopted in this paper is the Advanced Encryption Standard (AES). This algorithm is considered official and secure for encryption due to the length of the encryption key. Therefore, the secre key for AES is generated by implementing Elliptic Curve Diffie Hellman (ECDH) based public key exchange protocol, while the communication process between sender and receiver is employed by using a light communication technology called light Fidelity (Li-Fi). Meanwhile, Li-Fi technology supposed to be very secure and fast much more than the Internet used in our daily life.
