A Robust and Secure Cryptanalysis Using Logical Scrambling with Histogram Matching

B. Bharathi, P. Suresh Kumar, Srikanth A.


Abstract

Transmitting an image is an important and challenging task with higher security. The process of
secure data transmission with scrambling and jumbling is known as cryptanalysis. This can be used
inmany applications for confidentiality such as military, medical, satellite and web etc. Here, we
introduced a new and novel cryptanalysis scheme with improved security using logical scrambling
and histogram matching. The proposed algorithm can be easily adapted for real time application due
to its ease of access and less storage capacity. Experimental analysis has been done on various test
images such as medical, satellite and few of real images, also compared the original and decrypted
images with histogram matching and subtraction approach

Key words: Cryptanalysis, bit planes, logical scrambling, histogram and bound map
