The Design and Implementation of an Encrypted U-Disk Based on NFC

With the popularity of USB3.0, consumers favor a mobile storage which is convenient and efficient. But in the same time, people often pay less attention to the Safety of traditional mobile storage, especially the U-disk, the security of which is almost ineffective. Challenged by severe test of current information security situation, designing a safe and reliable way to protect the user's privacy encryption has gradually attracted both the equipment manufacturers and the user's attention. As we can see among them, as a quick and secure identification technology, NFC gains a great application in mobile payment and authentication field. It also means a great momentum to popularize.Its unique convenience and safety guarantee in the applications has a wonderful prospect in replacing traditional security solutions. This paper discusses a actualization of a new encrypt U disk which is applied with the NFC technology,to understand the principles of NFC technology and its practical application of encryption, this paper can play a guiding significance.
