Problems solved by technology

[0002] U disk is a kind of equipment that is often used in daily office work. Generally, U disk can be used directly by plugging into the computer, so the security is very low, especially when there are important files stored in the U disk, if you accidentally miss it , it may be stolen or leaked by others
[0003] After retrieval, the authorized announcement number is: CN 203415235 U, and the authorized announcement date is: 2014.01.29. The Chinese utility model patent has announced a multi-functional U disk. and NFC antenna to expand other non-contact application functions, but the utility model does not involve the encryption function of the U disk, so it cannot realize the encryption of the U disk
[0004] Another example is a Chine

Embodiment Construction

[0015] See figure 1 with figure 2 As shown, an encrypted U disk 100 includes a CPU 1, a motherboard 2, a USB interface 3, a passive encryption IC 4, an NFC antenna 5 wirelessly connected to an NFC mobile phone (not shown), a Flash memory 6, A buzzer 7, an LED light (not shown), a battery 8 and an antenna board 9, the CPU1 is connected to the Flash memory 6, and the USB interface 3 is respectively connected to the CPU1 and the Flash memory 6 , The passive encryption IC4 is connected to the CPU1, and the NFC antenna 5 is connected to the passive encryption IC4;

[0016] The NFC antenna 5 generates a small voltage and current when it senses the NFC mobile phone. The generated voltage and current support the work of the passive encryption IC4 and CPU1. At the same time, the NFC antenna 5 receives the NFC mobile phone (the NFC mobile phone is installed with APP, when working, you can use the installed APP to send the verification code sent to the passive encryption IC4), and send th...

Abstract

The invention provides an encrypted USB flash disk. The encrypted USB flash disk comprises a CPU, USB interfaces, a Flash memory, a passive encryption IC and an NFC antenna in wireless connection with an NFC mobile phone. The CPU is connected with the Flash memory; the USB interfaces are respectively connected with the CPU and the Flash memory; the passive encryption IC is connected with the CPU; and the NFC antenna is connected with the passive encryption IC. The encrypted USB flash disk provided by the invention has the following advantages: the NFC mobile phone can be used to send an identifying code to the encrypted USB flash disk so as to realize decryption and unlocking as well as locking of the encrypted USB flash disk no matter in an on-line or off-line state; the encrypted USB flash disk is automatically locked when pulled down after usage; and the encrypted USB flash disk is convenient to use and can effectively guarantee data security.

Description

Technical field [0001] The invention relates to an encrypted U disk. Background technique [0002] U disk is a kind of equipment that is often used in daily office. Generally, U disk can be directly inserted into the computer and can be used, so the security is very low, especially when there are important files stored in the U disk, if you accidentally omit it If it fails, it may be stolen or leaked by others. [0003] After searching, the authorized announcement number is CN 203415235 U, and the Chinese utility model patent of the authorization announcement date: 2014.01.29 published a multifunctional USB flash drive, which not only supports the storage function, but also can pass the embedded NFC chip It expands other contactless application functions with the NFC antenna, but the present invention does not involve the encryption function of the U disk, so it cannot realize the encryption of the U disk. [0004] In another example, the application publication number is CN 103532...
