-comment1: CSEEC is the name of the study, therefore the implementation was specific to it. Does that mean I need to add anything. [I would just spell out what the study name is, e.g., Computer Science... (CSEEC)]
 -comment5: it is believed by us, the designer and implementer [I would remove "it is believed" or state "we believe that..."]
-comment6: Its suppose to be (FPGA devices and implementation) and (synthesis tools). so where should I have "the"? before the implementation or synthesis [change second "and" to "as well as"]
 -comment7: the "on the other hand" was meant to compare with the number of clock cycles to encrypt [change "on the other hand" to "in contrast"]

comment8&9: if I said "to encrypt a block" do I need to say "to decrypt a block" [no, just the first time should be okay]
