A Generalized Pseudo-Knight?s Tour Algorithm for Encryption of an Image
A Wilsey Philip · IEEE Potentials · 2013
With more data being stored and transferred in some digitized form, it is becoming considerably easy for unauthorized people to access this data. It is important to have measures to hide data considering the inevitability of it falling into wrong hands. Measures like symmetric key cryptosystem protects against such threats. But sometimes even such systems or an algorithm can be broken without the key making it, so it is important to ocassionally use unorthodox methods to create a fail-safe system that can hold on for some time since, eventually, every algorithm has a glitch that can be exploited and analyzed against the algorithms integrity. Any encryption system can be made to work around a pseudo-knight's tour (PKT) matrix. The encryption process itself is very flexible and can be built around PKT, rendering the user of PKT the required level of security of the system.
