Research And Implementation Of Secure Element Based O2O Electronic Certificate System

Since the concept of 020 had been proposed, it attracted widespread attention. Especially with the popularity of smartphones and the advent of the era of mobile Internet,020 model had entered into a period of vigorous development. As a key point of the connection between online and offline, the electronic credential was challenged with increasing demands, which attracted attentions of many scholars both at home and abroad. This was also the content of the thesis.Currently, electronic credential information was usually stored in the smart phone, and managed by its operating system. However, the operating system of the current mainstream smartphone had its hidden danger, and the situation of its safety was not optimistic. For instance, the confidential information such as the user’s secret key might face the risk of being stolen or tampered. To solve the problems above, this thesis carried on a detailed study on how to introduce a security element into the 020 electronic credentials system, how to get the user’s confidential information stored in the secure element, and how to protect the interests of the consumers and the issuer of electronic certificates by using of digital signatures and other security technology.The main contributions of this thesis are:1.Studies on all kinds of demand of electronic credentials under the 020 environment; 2.Studies on the combination between the security elemenet and smartphone 3. Studies on the methods of issuing and converting the electronic credentials both online and offline (the online part based on the internet meanwhile the offline part based on the qr code and the NFC tags).4. On the basis of all the studies above, the author proposed the secure element based 020 electronic credentials system which was tamper-resistant, anti-counterfeiting, anti-repeated and has the function of identity binding.5. Designed and implemented the 020 electronic credentials system. To sum up, the main content of the thesis is to research, design and implement the secure element-based 020 electronic credentials system. Among them, the introduction of the security element is the innovative points of this thesis. Security element and its interactions with other parts of the system are also the focus of this thesis.
