Sample Research Paper on WhatsApp security system

WhatsApp security system

WhatsApp is one of the most popular applications on the market offering secure video, pictures, and text messages services. Compared to other applications, WhatsApp mobile application for I-phone has authentication mechanisms that are properly designed and well implemented. It puts security first whereby it has true end-to-end encryption and the users are certain that no other intruder can read their messages, even the server operators have absolutely no way to view users’ messages. The application always requests for user’s phone number in order to send verification requests to the host server. Then, the host server creates an authentication code, which is sent to the user’s phone through an SMS message. This mechanism ensures that the communication between the users is secure. Additionally, the application offers a secure capability to import another user’s contacts automatically.

Even though this system has no feature to retain chat history, and the system deletes messages after delivery, the recipient’s device might not be protected. Security researchers have pointed out that there are vulnerabilities in the security system. The WhatsApp encryption and security are not perfect and cite susceptibilities on how it handles the SSL (secure socket layer) protocol for communications. The researchers have realized that it is possible for hackers to downgrade the encrypted data and break it into the user information that transits to the back-end servers. There is susceptibility in question that involves the use of a similar key in decoding encrypted data on both sides of a chat that makes it possible for a hacker to interrupt messages sent through WiFi and decrypt them. In this case, once an attacker accesses the encrypted message can use certain techniques to compare and effectively predict the encrypted text. These security problems engage WhatsApp users’ conversations and data at risk.
