Abstract: Smart phones have become an essential part in the life of the individuals and their priorities at the present time. The most prominent uses are in chatting and conversation applications. Most of these applications do not provide the required protection and privacy of the data exchanged between users. Yet there are very few mobile chat applications that provides an end to end encryption service to their clients. Due to that, there is a need for secure chatting application with end to end encryption that provide complete security and privacy for the user. In this study, a secure chatting application with end to end encryption for smart phones that use the Android OS has been proposed. The proposed application uses the ECDH algorithm to generate the key pair and exchange to produce the shared key that will be used for the encryption of data by symmetric algorithms, AES for text encryption and RC4 for voice and image encryption.
