VLSI Implementation of Text to Image Encryption Algorithm based on Private Key Encryption

Cryptography, also referred to as encipherment is used to convert a plain text to an unreadable form of text. The data to be sent are encrypted on the sender side using encryption algorithms and keys to have them hidden and protected from unauthorized access and then sent via the network. when the data are received they are decrypted depending on an algorithm and keys to retrieve the original data. This way only the receiver can have the original data.
