Development Of A Secure Messaging App For Android Mobile
Résumé: Nowadays the easiest way to connect with people is chatting by using Mobile Chatting Applications, which offers us a lot of helpful facilities. However, different Chat Applications offers different security to users but leads to increase in vulnerabilities & risks of attack on data. To overcome this kind of vulnerabilities and risks of attacks on data we need apply security mechanisms for a secured conversation. This project suggests a novel encryption scheme for instant messaging (IM) communication that uses multiple rounds of encryption to provide better privacy to the transmitted message against unauthorized access. An AES encryption algorithm with CBC (Cipher block chaining) mode is used to encrypt the message while the message is being sent. In this system, user only can decrypt the software-encrypted message in time of accessing the conversation by introduction of the encrypted user’s define key. Through this approach of encryption, it can create more powerful security for data transmission.
