博士 === 國立臺灣海洋大學 === 資訊工程學系 === 102 === The rapid growth of network communications has made applications of electronic commerce the future trend of commercial activities. To ensure the effectiveness of transactions, governments put the electronic signature law into practice. They also proposed guiding or assisting projects to encourage or help enterprises and organizations to construct secure electronic environments. Because of the availability and ease of use of information infrastructure, human’s daily life is increasingly digitalized. With the promotion of life education and religious groups, people have gradually accepted the concept of writing down wills before their death, which can reduce conflicts and arguments for inheritance. A legitimate will can be produced with the witness of notaries in the court or the notary public offices. If a testator wishes to modify his will, he must perform again the procedures above. Since it requires some fees as well as transportation costs for notaries and witnesses, the generation of a traditional will is rather costly. Based on the mechanisms of public key infrastructure, this thesis constructed a secure and realistic model for a digital will system which is suitable for practical implementation. Furthermore, this dissertation shows through the simulation for the formal security verification using the widely-accepted AVISPA tool that the model is secure against different attacks, including the replay and man-in-the-middle attacks. Currently, the electronic Wills Act is under discussions, but not put into practice yet. To date, there are no literatures to discuss the issues of digital will, but except the introduction of [48], as far as we know. The properties of security, convenience and effectiveness are the most significant reasons why people would like to adopt the digital will mechanism in the future. The proposed digital will system not only achieves lots of essential security requirements of network but also fulfills the above-mentioned properties, which provides a practical solution of this subject for the related researches in the future.
