Abstract
In this paper, a secure chatting application with end to end encryption for smart phones that used the android OS has beenproposed. This is achieved by the use of public key cryptography techniques. The proposed application used the Elliptic Curve DiffieHellman Key Exchange (ECDH) algorithm to generate the key pair and exchange to produce the shared key that will be used for theencryption of data by symmetric algorithms. The proposed Application allows the users to communicate via text messages, voicemessages and photos. For the text message security the standard AES algorithm with a 128 bit key are used. The generated key (160 bit)minimized to 128 bit length by selecting the first 128 bit of the generated key in order to be used by the AES algorithm. For the voice andimage security processes the proposed application used the symmetric algorithm RC4 for this purpose.
