Objective: This work is a review of image encryption algorithm using a key image, namely a secure image encryption algorithm based on bitplane principle. Method/Analysis: The analysis of the algorithm is done in terms of the parameters like histogram analysis, Number of Pixels Change Rate (NPCR), Unified Average Changing Intensity (UACI), Mean value analysis and Correlation coefficient. Findings: The results show that the algorithm reviewed offers commendable security against common types of attacks. Conclusion/Application: Most of the image encryption techniques have some security and performance issues. So there is a need to evaluate and analyze the efficiency of the algorithms used for encryption. These parameters are useful in judging the quality of encryption algorithms and can also be used for checking the level of security, the method actually provides to the actual image.Keywords

Objective: An Image Encryption algorithm is proposed which uses an image as key and concept of Edge Map for Encryption. Method/Analysis: The proposed algorithm uses gradient operators like Sobel, Roberts, Prewitt and Canny edge detectors for generating the edge map of key image and which is used for encrypting the original image with xor operation. Findings: The encrypted image shows remarkable difference from the actual image which is shown in the histogram analysis and other statistical tests. Conclusion/Applications: The proposed algorithm achieves considerable level of encryption, which makes it suitable to be used in different applications. It is used for protection of images against various kinds of common attacks like brute force attacks.Keywords
