Strong and Efficient Cipher with Dynamic Symbol Substitution and Dynamic Noise Insertion

Abstract

As our dependency on the digital world increases, our private information becomes widely visible and an easy target. The digital world is never safe and is full of adversaries who are eager to invade our privacy and learn our secrets. Leveraging the great advantages of the digital world must necessarily be accompanied by effective techniques for securing our information. Although many techniques are available, the need for more effective ones is, and will remain, essential. This paper proposes a new, robust and efficient encryption technique. Our technique has an innovative computational model that makes it unique and extremely effective. This computational model offers (1) a fuzzy substitution method augmented with distortion operations that introduce deep changes to their input and (2) a key manipulation method, which produces key echoes whose relationships to the original encryption key are highly broken. These operations work synergistically to provide the highest degree of diffusion and confusion. Experiments on our proof-of-concept prototype showed that the output (cipheredtexts) of our technique passed standard security tests and is therefore highly immune against different attacks.
