A Hardware Solution for an “On the Fly” Encryption

This paper presents an implementation of a secured transmission of binary data, using a hardware encryption based on multiple keys, stored in a small read-only memory. The advantages of such a solution are the increased speed of encryption (since a hardware implemenation is much faster than a software one) and an automaticprocess (since the user doesn’t have to provide himself the keys for encryption/decryption). Also, the paper presents the results of simulation obtained using the Quartus II Web Edition 9.0 design software provided by Altera.
