Secure Communication over Android Handset

Abstract

Messages play important role in communication, because they may carry our personal information, such as our PIN code, transaction details, passwords, and personal details which is secret etc. Thus security of messages is also necessary. There is a need of security application which can send all messages securely. There is also a problem with the encryption algorithm, which is best suited to mobile device. Blowfish is an algorithm which is best suited for security purpose on handset devices. Along with the encryption technique of Blowfish, One more security that can be added is an application accessing login. Application accessing login asks for username and password. Through application accessing login, the security of messages also increases, even after the handset is handed over to someone else. The message sent over GSM network, Bluetooth message passing and message sent over internet all are merged into a single application. Thus the security is doubled and privacy to messages can be achieved.
