碩士 === 國立臺灣科技大學 === 資訊管理系 === 103 === The concept of copy protection mechanism based on dynamic loading for android application was proposed by Tsai, Chiu and Wu in 2014. To prevent the application suffering unauthorized copy and distribute, when unauthorized users obtain the application installation file, they must pass the authentication or they can’t execute application fully function. However, this mechanism cannot effectively authenticate the correctness of the user identity that cannot resist the authorized users to share their personal identification information to unauthorized users. Therefore, we adopt undeniable signature to withstand application clone attack to ensure that only authorized users can pass the authentication to obtain the application resource files to execute application fully function. In our proposed method can achieve authenticity, integrity, confidentiality, non-repudiation, mutual authentication resistance, replay attack resistance, man-in-the-middle attack resistance. Finally, this method can be used to withstand the application suffering unauthorized copy and distribute attack, and can also reduce complexity of computation and communication costs.
