    Abstract:

    For the present article, I use a symmetrical cryptographic method based on symbols transposition: Hill's cipher. This consists in a symmetrical approach based on modulo m arithmetic. The theory says that one has to choose a prime number as the length of the modulo-m space used. Nevertheless, based on my conclusions here, this choice is not mandatory. As a proof of concept for the supportive case study, I chose a computational medium based on a system-on-chip solution offered by Texas Instruments, namely Beagleboard. The main purpose is to emphasize the original concepts that I introduced along my PhD thesis, 'self-recognition' and 'symmetrical copy'. The data restoration operation that accompanies the set of compression/ decompression operations that I proposed requires the generation of a file called 'symmetrical copy'. The overall details of the above mentioned new concepts can be found in my PhD thesis - “Real-time compression/decompression algorithms applied to embedded systems”. That very practical context is one of the possible situations within which Hill's cipher still suits.
