Explaining HTTPS using carrier pigeons

Filed under: Interesting Sites,Security Tutorials,Techie Stuff — Suramya @ 7:07 PM

HTTPS is something that a lot of people find hard to explain without going into a lot of technical jargon which frankly just confuses most people and causes them to zone out. However it is an essential service/protocol so understanding it is a good idea. To address this issue Andrea Zanin who is a student created the following primer that explains how HTTPS works using carrier pigeons as the messengers.

Below is an explanation on how HTTP would work with carrier pigeons:

If Alice wants to send a message to Bob, she attaches the message on the carrier pigeon’s leg and sends it to Bob. Bob receives the message, reads it and it’s all is good.

But what if Mallory intercepted Alice’s pigeon in flight and changed the message? Bob would have no way of knowing that the message that was sent by Alice was modified in transit.

This is how HTTP works. Pretty scary right? I wouldn’t send my bank credentials over HTTP and neither should you.

Check out the link for the full writeup.

Well, this is all for now. Will write more later.
