Robustness and security enhancement of SHA with modified message digest and larger bit difference

Now a day's data is transmitted between users through internet in the form of multimedia. The data transmission requires less time complexity as well as security of data, security is the big issue during transmission of data. Data integrity is one of the major parameter to ensure the security. There are many algorithms or methods have been developed for maintain the integrity of data during transmission. Numbers of algorithms have been proposed to provide integrity but almost all of them proved to be breakable or less secure in terms of execution time and bit difference. So to increase the security a novel SHA is introduced, that possess less execution time and better bit difference value.
