A Wireless Secured Direct Data Transmission Between Authenticated Portable Storage Devices Through GSM Network

摘要

A secured data transmission has become a great challenge especially in education system. The question paper transmission during examinations needs a fast, highly secured with proper authenticated system. In this paper, a secure and fast way o f direct end to end data transmissio n is proposed. This system acquires the data from storage device and transmits the data securely to another storage device through wireless network. The microcontroller based secure data transmission system communicates through GSM/GPRS modem. This system helps for question paper transmission just before the commencement of examinatio n, where th e authorized person at Head Office or University can send directly to the educational institution itself.
