The Importance Of Cybersecurity In The Digital Age: A Demonstration

It seems everybody's hyped up about hacking these days. It's no surprise, given just how many people rely on technology for important things like banking, communicating, and personal entertainment.

Ehlers Video knows the value in keeping their clients -- and their intellectual property -- safe and encrypted. With the power of a mega-conglomerate like Ehlers, you can trust that they have the resources to lock down every part of their operation. That means they would never do something like leave a hidden admin backdoor to one of their lesser visited sites -- Ehlers security is top-notch.

But don't just take it from me, head of security for Ehlers Video. Let me explain in great detail just how Ehlers uses encryption to keep you and your files safe.

Modern cybersecurity relies on a concept called "private key encryption." Essentially, a provider (i.e. Ehlers) holds on to a very valuable piece of data called a "key," which is kept private. that key can be used to modify other data so that the only way to get the original data back is to use the key; otherwise it looks like gibberish.

Back in the day, soldiers would use a type of key called a "one time pad" to accomplish this same feat. Everybody on the same side would agree on a bunch of letters called a "pad," and use that pad to encrypt their messages. That way, if a message gets intercepted, nobody would know what it said unless they also had the "pad." It's that easy.

Check out this demo for a "one time pad." Imagine that you're a soldier, and the pad you were given for that day was "THVMJXWZJSRBKOYLYXYOERVJEZKTHYJX."

If you were given the message "YBGXBQNHTWRUDVGCRBCBLLIMVDNAVSAP," would you know your instructions?
