Define Word/byte rotation and XOR bit masking encryption technique to make sure secured transactions on the net?

Word/byte rotation and XOR bit masking:

In this process the words or the bytes into a data stream are rotated, by using multiple and duration of rotation and variable direction. It is nearly not possible to break. Additionally, the use of ‘XOR mask’ in combination along with this makes the code breaking process even more complicated.
