In the past few years a new generation of mobile messaging systems have been developed in conjunction with the explosive growth in the use of smart phones. As this technology enabling for accessing Internet based services, the new-generation the messaging applications was directed to play the role of traditional text messaging(SMS). Such applications require only the user’s phone number for registration. Unfortunately, these appl1icationsdo not provide a built-in support for any security feature. Sometime, the basic security features (e.g., authentication and confidentiality between the communicators) must be ensured in messaging service. In addition to that, most of the modern communications via internet takes place "through the air"; therefore the risk of interception becomes greater than in case of wired networks. If the message is not encrypted, or encrypted using a weak algorithm, the attacker can get it and may make hard harm. This paper presents a security solution to ensure confidentiality and authentication of exchanged messages, the users of proposed system can communicate exclusively via web server and by using a dedicated android application. The exchanged messages are encrypted using stream cipher RC4 with a personalP2P dynamic encryption key.
