First SN P visual cryptographic circuit with astrocyte control of structural plasticity for security applications

Cryptographic algorithms have been widely used in all secure data transmissions due their capabilities to hide sensible information against eavesdroppers. Nevertheless, technological progress tends to develop new cryptographic methods based on non-classical computing paradigms. In this work, the first circuit of visual cryptography based on Spiking Neural P systems (VCSN P) is presented. The proposed circuit makes use of new biological behaviors in astrocytes, which are involved in processes of plasticity and pruning control in dendrites, that can be the beginning to new cryptographic algorithms based on SN P systems. To validate the SN P circuit, this was implemented on the Cyclone V field programmable gate array (FPGA) development kit. The results demonstrate that this new approach exploits the features of the SN P systems to improve the cryptographic algorithm.
