Mobile wireless has detonated in popularity just of its simplicity, revolution in communication and Mobile computing has become very famous now days in reward of the services offered during the mobile communication and. Mobile computing has become the reality not the luxury. Mobile wireless market is increasing by leaps and bounds as Cell phones, mobile computing and communication devices have become very trendy because of their ease and portability. However, the use of such devices in this platform is accompanied by new security risks that must be recognized and addressed to protect the physical devices, the communication medium, and the information used. Security is key issue that needs to be considered. For this security protocols are proposed for different applications like Wireless Application Protocol, 802.11a etc. Most of them are based on the public and private key cryptography. The challenge for mobile network is in providing very large footprint of mobile services with high speed and security. In this paper, we have discussed security issues arising due to wireless networking of mobile computing in distributed systems. We discussed the operational model of mobile computing environment, and try to demonstrate proposed solutions. We also discuss security problems and mechanisms that can be applied one of three main components of mobile computing. The goal of paper is to point out some of the limitations, characteristics, applications and issues on security of mobile computing.
