A Secure method for Image Signaturing using SHA 256, RSA, and Advanced Encryption Standard (AES)
Also Available Domains Xilinx Vivado|Xilinx ISE
Objective
The core idea of this paper is to confirm whether the given image is original or manipulated one. Even though a single pixel varied means it will identify. This will identify using the 3 different algorithms SHA, RSA, AES.
Abstract
Cryptography is associated with the process of converting ordinary plain text into ambiguous text and vice versa. Hardware Security plays a major role in most of the applications which include net banking, e-commerce, military, satellite, wireless communications, electronic gadgets, digital image processing, etc. There are three types of cryptographic techniques; Symmetric key cryptography, Hash functions and Public key cryptography. Symmetric key algorithms namely Advanced Encryption Standard (AES), and Data Encryption Standard use the same key for encryption and decryption. The signature of the image is done through 3 steps. The three steps include SHA256 (Secure Hash Algorithm 256), RSA (Rivest-Shamir-Adleman), and AES (Advanced Encryption Standard). The signature of the image is stored in a binary file which is sent to the person who needs to verify the image that is already present near the viewer. The method has been tested y artificially applying attacks such as blurring the image greyscale the image and changing one pixel in the image.
