Security is the fundamental requirement of modern computer systems. Today critical information is stored, accessed and passed in all types of applications. Designing secure systems is a challenge due to the distributed nature of modern systems .Network communications are both wired and wireless .Security threats and attacks must be evaluated and handled. Distributed Mobile system has arisen as an evolution of distributed systems mainly focused on the sharing of resources and access information in a synchronized, secure, efficient and reliable manner. M-commerce and M-business have become a vital topic as new generation of wireless networks. The advancement of wireless devices enables users to access business information anywhere and anytime. Security algorithms used for wired networks cannot be applied to wireless systems, since wireless network clients come with limited resources and processing power.. The main objective of this paper is to provide secured transaction in Mobile system based on delegate object model. The model implements security in two instances at object access level and content level. The access privileges are based on a combination of the identity of the user seeking access, its credentials. The content level security is implemented using Tiny Encryption Algorithm. The critical data needs to be secured.. The proposed model uses the client side encryption and de encryption (Mobile Host) and ensures data is secured even from Mobile Support Station.
