Short Message Service is usually used to transport unclassified information, but with the database management system elmasri navathe 5th edition pdf of mobile commerce it has become an integral tool for conducting business. However, SMS does not guarantee confidentiality and integrity of the message content.
This paper proposes a protocol called SMSSec that can be used to secure an SMS communication sent by Java’s Wireless Messaging API. The physical limitations of the intended devices such as mobile phones, made it necessary to develop a protocol which would make minimal use of computing resources. What distinguishes this work from conventional protocols is the ability to perform the secure transmission with limited size messages. Performance analysis showed that the encryption speed on the mobile device is faster than the duration of the transmission. To achieve security in the mobile enterprise environment, this is deemed a very acceptable overhead.
Furthermore, a simple mechanism handles fault tolerance without additional overhead is proposed. Check if you have access through your login credentials or your institution.

Modelling of requirements has been occurring for many years and the techniques used have progressed from flowcharting through data flow diagrams and entity-relationship diagrams to object-oriented schemas today. Unfortunately, researchers have been able to give little theoretical guidance only to practitioners on which techniques to use and when. Two particular criticisms of the models have persisted however—the understandability of the constructs in the BWW models and the difficulty in applying the models to a modelling technique.
