In this paper we discuss Image Encryption and Decryption using RSA Algorithm which was earlier used for text encryption. In today’s era it is a crucial concern that proper encryption decryption should be applied so that unauthorized access can be prevented. We intend to build a general RSA algorithm which can be combined with other image processing techniques to provide new methodologies and better encryption decryption efficiency. One such implementation is by using edge detection method and converting the images to their filtered form. CUDA is a platform for parallel algorithm implementation using CPU with GPU support. The following technique has been implemented on CUDA considering host and device interaction process. Thus, to make the algorithm more efficient we parallelize the algorithm using CUDA block and grid methodology.
