留學(xué)英語作文：計算機(jī)科學(xué)（個人陳述）

Currently, I have come to the final stage of my Master’s dissertation entitled Research on the WLAN Security Solution and its Realization. In this dissertation, I focus on the security mechanisms of WLAN, proposing that VPN as a security solution can only be an alternative and that only the application of the true “point-to-point” mechanism can maximize network security at reasonable costs. My dissertation has an overall theoretical framework, supplemented by detailed plans and designs. In my repeated discussions with my supervisor concerning my dissertation, he has given his full support of my propositions. He has given special praises on my ideas regarding the renovation and development of the existing computer technology.

While perfecting my ability to carry out independent R & D projects, my past research experience has also enabled me to ferret out my own research interests for the future—Wireless Networking and Network Security. WLAN is one of the most important issues in the theoretical research and technical development of present-day computer science and its security mechanism is the key point. I have 4-year work experience as a network engineer and taught six courses on network and Internet technology. In my Master’s program I have concentrated on computer network and distributive system and my dissertation is on WLAN and its security mechanism. For each of those two concentrations, I have participated in two research projects, thus I have adequate practical experience. In my 10 research papers, 6 are concerned with those two major fields, which fully testify to my theoretical buildup and my important research potential. All those constitute my important assets for more advanced academic pursuit, in which I expect to exploit them to the fullest possible extent.

I wish to apply for a Ph. D. program in computer science from your esteemed university because your program satisfies my wish for a full development of my research interests. My past education and research experience has fully convinced me that, as home of the world’s modern computer science and technology, the United States is the ideal country that offers the advanced education and training that I am seeking. There, I will be exposed to the instructions of world famous scholars and experts whose academic ideas will significantly broaden my academic horizon. Equally important is that I can enjoy an inexhaustible variety of library resource. In conclusion, I deem myself fully qualified and well prepared for your Ph. D. program and it is my belief that your university is precisely the starting point of my new and rewarding academic journey.
