Going to take a certification that involves binary?

Going to take a certification that involves binary?

Here’s a quick tutorial~

Let’s say you are given an IP address of 192.168.1.135 in an answer.

What is this number in binary?

Here’s what you do.

Take a simple key to convert the numbers in the octets into binary.
The key is this:

128   64   32   16   8   4   2  1

Now let’s take the first octet of 192 and let’s see how many times the numbers above (the key) go into the given octet.

How many times does 128 go into 192?     192 – 128        1 time
This will leave us 64.
Next, how many times will 64 (your remaining number) go into the next number in the key(64)?

64 -64       1 time

Now the remaining number is 0.   So if you subtract 32 from 0 the number will be 0.  16 from 0 is 0, 8 from 0 is 0, 4 from 0 is 0, 2 from 0 is 0 and finally 1 from 0 is 0.

Look at your answers. 11000000 -This will represent 192.

Now let’s do the 168 octet.

128 goes into 168 – 1 time.   The remaining number is 40.   64 goes into 40 – 0 times.    32 goes into 40 – 1 time.  This gives you a remainder of 8.   16 (the next number in the key) goes into 8 how many times? 0 . 8 goes into 8 – 1 time.  The remainder is now 0.    4 goes into 0 – 0 times.   2 goes into 0 – 0 times.  1 goes into 0 – 0 times.   Look at your answers (bold).

168 will be 1010100

Of course the next number (third octect) which is 1 will be 00000001.

If you use the above key for 132, along with the subtraction method, 132 will be 10000100.

Your final answer is 11000000.1010100.00000001.10000100

 

Try a these yourself using the subtraction method above -

192.168.1.32
192.168.1.111

 

Flip over and see the answers

Can Hackers Steal Secrets from Reflections?

I encourage my students to go over and visit Rick, Paul and Bill’s blog.  In 2009, Rick posted a link to a Scientific American article on How Hackers Steal Secrets from Reflections.   Great Article.  With our students going through some of the best security courses available, these links are very valuable.

Although we used a mirror for this example, we have tried glasses and other reflective materials and you can take a picture and reverse the photo.
