Science and technology has reached such heights that with the click of a button you can communicate from one corner of the world to the other in a matter of seconds! Gone are the days when you had to tie a message to your carrier pigeon’s leg and throw it out of the window and hope that it comes back.
Today we have the internet and mobile phones. And we have calling over the internet and internet facilities on the mobile phone! Such is the digital age.
And when so many people rely on these modes of communication, they should be guaranteed that no one is eavesdropping and that they always have the warm blanket of security wrapped around their shoulder. No one wants their phone or their email conversations on a tabloid for the world to read and this is where cryptography steps in and takes your side!
This section deals with how cryptography enhances security over the internet as well as mobile phones. Read about the underlying technology.
So the next time you talk on the phone, take comfort in the fact that whatever you said is in between you and the other person. No one else.
