this is a paper on image encryption using cipher feedback mode

Ciphers are used to produce messages which can be understood only by the sender and authorized receivers, so ciphers can be used for secret correspondence in situations where the message may fall into the wrong hands. The process of converting a

its a ceasor cipher program made in java used for encryption of the messages sent from one user to other

In this paper, four chaotic maps are compared and noise effects are observed on image. Firstly, we use the image encryption algorithm to convert original image to encrypted image. Now we apply noise on the encrypted image and then decrypt ciphe
