Is there any EXE file maded which can convert a hex file into a scrambled data? and Then is there a clear C code which can convert the recieved blocks back to the original HEX.

I am not absolutely certain I understand what you require this program to do. Is it simply that you are looking for a PC program that reads as its input, an Intel HEX file containing an 8051 program image, then encrypts that 8051 program image and outputs the encrypted image in Intel HEX format?
