WhatsApp headquartered in Mountain View, an online messaging service now owned by tech giant Facebook, that has grown into one of the world’s most important messaging applications on all our smart phones. More than a billion people send messages, make phone calls, exchange photos, and swap videos using the service.
The enigmatic founders of WhatsApp, Brian Acton and Jan Koum, together, revealed that the company has added end-to-end encryption to every form of communication on its service.And you all must be seeing tip message in the app about the encryption of messages .
It might be difficult to understand what it means so we are going to explain what it means and how it will help the people using whatsapp.
WhatsApp’s end-to-end encryption is available when you and the people you message use the latest versions of our app. Many messaging apps only encrypt messages between you and them, but WhatsApp’s end-to-end encryption ensures only you and the person you’re communicating with can read what is sent, and nobody in between, not even WhatsApp.
This is because your messages are secured with a lock, and only the recipient and you have the special key needed to unlock and read them. For added protection, every message you send has its own unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.
Concept Behind Encryption
Theoretical concept (the protocol)
The protocol used is the same that is used by TextSecure .
The protocol is based on Off-The-Record-Messaging and provides Perfect Forward Secrecy . That means, it ensures that:
- Nobody but the receiver can read your message, not even the servers involved in transmitting the message (this is what end-to-end encryption is for)
- If someone breaks a key involved in the message exchange, it can be used to decrypt one message at most, since new keys are generated for every individual message. This is Forward Secrecy.
This means that the protocol promises to be very secure, and not even the most powerful government agencies will be able to crack it in a reasonable amount of time – as far as we know.
Whatsapp’s rollout of strong encryption to hundreds of millions of users may be an unpopular move among governments around the world, whose surveillance it could make far more difficult. Whatsapp’s user base is highly international, with large populations of users in Europe and India.
So this is the great news for all the whatsappers and will help to keep the things private.
