comment How to hide bit frequency of the inter-packet delays covert channel?
@HeatfanJohn as shown in the code, I use plaintext encoding in ASCII. The direction I'm going to is improving how to map the bit 1 and 0 to the packet delay. The code is the second improvement, the first is use certain delay time to represent 1 and 0, like 0.3ms is bit 0 ', 0.6ms is bit 1`. which obviously raise suspicion, the chart will show only 2 hight, thus easily to be broken. So you can see what direction I'm heading into

@ewanm89 it's python, and if I can change the value of z h u to number that equal or smaller than 76, than it works, I just change the number and run the program again, the result is same as expected 16 77 55 25 0 55 16 0 55

@Polynomial thanks for your quick reply,it starts to make sense that in the textbook it says the p,q must be prime 1,024bits or above
