FPGA Implementation of Cryptographic Algorithm Using ASCII Conversions for Secure Communications
International Journal of Science and Research (IJSR) · 2016
In today's world cryptography has become a necessity for all the organizations.Data security is an essential component of an organization in order to keep the information safe from various competitors.It also helps to ensure the privacy of a user from others.It helps us to securely access bank accounts, electronic transfer of funds and many more daily life applications.In this project it introduces a new algorithm for Cryptography to achieve a higher level of security.In this algorithm it becomes possible to hide the meaning of a message in unprintable characters.If a transmitter sends a message of plain text of 32 characters then according to algorithm it is divided into packets each packet is of 8 characters.Thus four packets are formed.Then in encryption the input is of 256_bit plain text where encrypted using ASCII conversions and cyclic mathematical function.From this 256_bit cipher text is formed.In decryption the input cipher text is of 256_bit where decrypted using ASCII conversions and inverse cyclic mathematical function.From this the original 256_plain text is obtained which can be sent to the receiver.
