| With the rapid development of Internet and Wireless network technology, Mobile E-commence is produced. In the wireless environment, security is crucially important to users and become a main obstacle of farther development of Mobile E-commence. As a model application of Mobile E-commence, secure protocols for mobile lottery are studied to settle the security problems in mobile trade.Based on research in foreign secure protocols for mobile lottery and it's application, main secure problems which exist in mobile lottery are pointed out.The paper discuses security demands of mobile lottery and compares current key issues in mobile security area, J2ME platform is very suitable for secure protocols for mobile lottery because of its advantages. Combining with WPKI technology, a third justness organization is also bring into secure protocol. The purpose of thesis is to design a secure application protocol for mobile lottery which is provided an end-to-end secure solution in application layer and settle the main security problems during the process in trade, such as justics, traceable, integrity, security and non-deny etc.By using formalization language, the whole process of trade is described in detail and secure protocol's security is also discussed. Finally, a testing envirment is built to simulate the trade of secure protocols for mobile lottery.The main research works of thesis are as follows:1. Based on analyzing extensive actuality of mobile lottery, main secure problems are pointed out.2. Comparing current key issues in mobile security area, their advantages and disadvantages are indicated.3. According to the principles of security protocol, we designed a security protocol for mobile lottery based on J2ME and a third justness organization (WPKI). By using formalization language, the whole process of trade is described in detail, and proved that the modal can make trade justics, traceable, integrity, security and non-deny etc.4. By using J2ME platform, we choose RSA encryption and signature algorithm to simulate the purchase and affirmation process and test the basic secure attacks. |
