摘要：This is an era of mobile communications and computing where mobiles are being used in place of traditional computers. Mobile devices are small, handy devices that can be carried around by the user very easily. A user holding the mobile device will have access to the information even at the places where no internet terminal is available. Due to this reason, they are heavily being used in the business environment in managing application, e-mail correspondence, accessing the remote corporate data, handling voice calls, etc. But the mobile devices are still lack-in most important security features such as user authentication, content encryption, virus protection, confidentiality, integrity, etc. The sensitive information stored in the mobile devices is not secure (can be accessed by an unauthorized user). Mobile device poses limited storage and processing power, and the low battery-power. It is also tedious to implement the cryptographic algorithms on mobile devices because they need heavy computations such as generating a key as a large prime numbers. Hence, many security threats are possible when mobile device is used. One of the most serious security threats is the unauthorized use of the mobile device. It is very common that mobile devices can be used by unauthorized person because they are handy and can be lost or stolen very easily. A smart card used with mobile device resist its ‘unauthorized use’. The limited computation capabilities of the mobile can also be enhanced by using the smart cards. In this paper , two novel types of smart cards such as Smart Multimedia Card Authentication(SMCA) and Bluetooth Smart Card Authentication (BSCA) are used. The authentication mechanisms proposed in this paper are based on Multimode Authentication Framework, which provides a flexibility to add our own authentication modules. The developed authentication mechanisms provide the dual-security to the mobile devices and are well enough to resist the attacks which are possible over mobile devices. Demand for competent software is rising day by day and object-oriented design procedure became able to fulfill this demand because it is the most powerful mechanism to develop efficient software systems. It can not only help in reducing the cost but also helps in the development of high quality software systems. Software developers need appropriate metrics to develop efficient software system. Object-oriented metrics can play vital role[10,11] in this aspect due to their importance in the development of successful software applications. Empirically we analyzed and deliberate the OO Metrics also in this paper
