Nowadays talking on the phone is not exactly as secure as you could imagine , since it is quite easy for the government , mobile phone operators and even clever hacker to eavesdrop on all your conversation . I highly recommend you to make an encrypted secure phone calls instead of making a regular phone calls , if you are having a confidential conversation with someone.
There are apps called RED PHONE APP that allows you to make end-to-end encrypted phone calls over wi-fi or mobile data connection using your normal phone number. Both parties should have app to make secure calls . For Iphone users there is an alternate available app called Signal app which is fully compatible with RED phone app.
Now let’s learn how to use it :
- First you open your RED PHONE app , it will ask you to register and verify your phone number via sms or phone calls . Keeping in mind privacy of its users , the RED PHONE app doesn’t ask you to enter any details like username, passwords , email- address etc.
- You need to make sure that person you are calling is also using RED PHONE app or SIGNAL app like whatsapp all your contacts who are using RED PHONE app will automatically gets displayed.
- Tap on the name of the person you wish to make secure call and the REDPHONE app will automatically create a secure line for you . And person on other side of phone gets displayed giving them a chance of either accept or reject the calls.
- To prevent impersonation of the person on the other end or any man i.e the middle style interception attacks , the red phone app displays the same pairs of words on the screen of both parties . So you can authenticate the identify of the person on the other end by saying the first word and asking them to speak the second .If both are having correct pair of words , then you know there is no impersonation taking place.
