Abstract

MMS is the popular technology that is being misused heavily in the present times. In this paper, we are suggested MMSSEC algorithm to prevent unauthorized users from viewing messages which are not meant for them. This algorithm uses encryption and decryption technique for securing communication. Introduction The Multimedia Messaging Service (MMS) can be seen as the ‘best of the breed’ of several messaging services such as the Short Message Service (SMS), the Enhanced Messaging Service (EMS) and the Internet mail. Since 2002, the first MMS wave offers basic messaging features to mobile users and a second MMS wave is already appearing. This second wave builds up from basic messaging functions to offer more sophisticated features, from photo messaging to video messaging. The roots of the MMS lie in the textbased SMS and the Internet electronic mail. Indeed, features already supported by these services have not been forgotten in MMS. MMS supports the management of reports (delivery and read reports), message classes and priorities and group sending. In addition, MMS differs from other messaging services with its multimedia capabilities, its support for email and phone number addressing modes, its efficient transport mechanism and flexible charging framework. MMS architecture The MMS client is the software application shipped with the mobile handset, which allows the composition, viewing, sending, retrieval of multimedia messages and the management of reports. For the exchange of a multimedia message, the MMS client that generates and sends it is known as the originator MMS client, whereas the MMS client that receives the multimedia message is known as the recipient MMS client. The MMS Environment (MMSE) refers to the set of MMS elements, under the control of a single administration (MMS provider), in charge of providing the service to MMS subscribers. Recipient and originator MMS clients are attached respectively to the recipient and originator MMSEs. A key element in the MMS architecture is the MMS Centre (MMSC). The MMSC is composed of an MMS relay and an MMS server. The relay is responsible for routing messages not only within the MMSE but also outside the MMSE, whereas the server is in charge of storing messages [1]. MMS Interfaces: In an MMSE, network elements communicate via a set of interfaces. Each interface supports a number of transactions such as message submission, message retrieval and message forwarding. Each operation is associated with a set of protocol data units with corresponding parameters. MMS Client: The MMS client is the software application that resides in MMS-enabled mobile devices and which offers the following features: a. Management of message, notification and reports: Devices are commonly shipped with a unified message box for the management of MMS elements (messages, notifications and reports) and other elements such as SMS/EMS messages, WAP push messages, and so on. b. Message composition: The message composer is used for creating new multimedia messages. c. Message viewing: The message viewer is used to render received messages or to preview newly created messages before sending. d. Configuration of MMS preferences and connectivity parameters. e. Handling of a remote message box stored in the user personal network-based storage space. Such storage space is known as a Multimedia Message Box (MMBox). The support of an MMBox is optional. f. MMS Centre: The MMS Centre (MMSC) is a key element in the MMS architecture. The MMSC is responsible for handling transactions from MMS phones and transactions from other messaging systems (e.g. other MMS systems, email systems, etc.). The server is also in charge of temporarily storing messages that are awaiting retrieval from recipient MMS clients. Optionally, the server may also support a persistent message store where users can store messages persistently in their MMBoxes. This feature is particularly useful when devices have limited storage capabilities. Working Of MMS through MULIPART In the MMS Environment (MMSE), a multimedia message can take multiple forms in order to be efficiently conveyed over the various transport bearers composing the full message transfer path. The link between an MMS client and the MMSSEC Algorithm for securing MMS International Journal of Machine Intelligence, ISSN: 0975–2927, Volume 1, Issue 2, 2009 31 MMS Centre (MMSC) is often bandwidth-limited (particularly over the radio part); therefore, multimedia messages are binary-encoded for efficient transfer over this link. Alternatively, the multimedia message is text-encoded for transfers over Internet protocols between MMSCs, from an MMSC towards the Internet domain or from/to Value Added Service (VAS) servers.
