نظام اخفاء متعدد المستويات بالاعتماد على الحمض النووي (RNA ) وخرائط التوزيع العشوائية

Abstract

In this paper we produced multilevel secure system, the first level based on crypto-system and the second level based on stego-systemIn the first level we have used RNA Overlapping Encoding to get cipher code, in the second level we have used chaotic mechanism to build random map that will used in hiding mechanism which based on seeds value to get hiding mapsthe cover image was of colored Image (RGB) of BMP type whereas the secret message in form of text file and the value of PSNR was in interval of [44.0, 64.0]
