The tags can be generated and copied easily and cheaply, so it is widely used in a variety of business sectors, also in mobile commerce. Since the tag specifications are open to the public and the tags can be read easily, the mechanism in the security mechanism is not perfect. Therefore, we suggest using NTRU encryption in barcode system to enhance security in mobile applications. It is expected to encourage mobile commerce. Compared to other asymmetric encryption systems, NTRU has the advantages of shorter key, speeder computation and higher security. It can even resist the attacks from future quantum computers. NTRU is seldom researched inlands; our study will help to better understand the system. Contribution of this paper will be on mobile commerce payment process to establish an effective and safe mechanism. Through the methods proposed in this paper, two-dimensional bar code can further expand its scope of applications. It can also avoid the risks in trading, so that customers and suppliers can complete their transactions more quickly and safely. It will help promote future business operations, by enhancing the trust of users in e.g. mobile business. On research methods, we focus on the study in NTRU theory, QR code applications, and compromise attacks. We will implement a prototype based on the NTRU public key cryptosystem integrated in QR code. and assess the effectiveness of using such a mechanism in mobile commerce. Advisor Committee Patrick S.
