These types of attacks either try to conceal the quality reduction caused by encryption by treating unbreakable data as lost and then trying to minimise the impact on quality as a result of loss (error-concealment ...
In all experiments the images were compressed with a target bitrate of 80000 bits, this leads to a compression rate of about 6.5 for 8-bit gray-level images with 256*256 pixels. ...
