Communication between devices and data through networks have been increasing drastically in the past few decades. Encryption of data provides high level of security. This paper presents a median based technique for selective encryption where partial data of image is encrypted based on pixel values. An encrypted mask of the image is also appended with the image that specifies the pixels that are encrypted...
In this paper FPGA implementation of a simple median based technique for selective image encryption is presented. Image encryption imposes heavy resource requirements on the hardware platform due to large size of data. Although Advanced Encryption Standard (AES) provides a high level of security to the image, it takes more time when used for image encryption. The technique presented in this paper...
