碩士 === 國立高雄第一科技大學 === 資訊管理研究所 === 103 === NFC (Near Field Communication) technology has been widely used in people''s daily lives. By using the NFC-enabled mobile device to read the security token from NFC tags, we can use cloud services over the mobile network. Due to the short distance physical communication constraint, the NFC has higher confidentiality and higher security. Thus, after completing the NFC communication, how to ensure data security between the user and the cloud server is another important issue. In the cloud environment, the digital content accessed by the user is mostly stored in the server. Thus, it needs to prevent malicious persons from modifying information and faking the user''s identity to obtain the digital content. In addition, in the cloud computing environment, it is required to consider the storage space and computing performance problems for the mobile device. In this thesis, a secure and efficient NFC identity authentication and digital content protection scheme is proposed. We use an NFC tag to store the security token and other related parameters, and put the tags in a protected environment in order to prevent it from being damaged or tampered by malicious persons. Through the NFC side-channel, a user needs to near the NFC tag to access the security token. In addition, we use the challenge-response protocol and the message authentication code to achieve mutual authentication, and generate the session key to protect the transmitted digital content.
