Cryptography and multiplicative arithmetic functions

The security of information has become even more important with the increased use of the internet, mobile communication and even social networking, all of which have intensified the volume of communication among individuals, institutions and governments to a great extent. In this regard, the use of novel cryptographic keys and their construction has become very important. Here, we outline methods for using multiplicative arithmetic functions together with Hill k-CypherCodes for secure transfer of information.
