In this paper, the authors present a new cryptographic technique for secured transmission of text and image data over communication networks. The new algorithm named Fixed Block with Dynamic Key (FBDK) is designed using simple operations like XOR, circular shifts and substitutions. It uses input fixed blocks of any size based on the size of the original message bits and key size is dynamic for each block which makes it more resistant to cryptanalysis. The performance analysis of FBDK algorithm for digital images, text data is performed.
