Problems solved by technology

Common local data encryption using software encryption has the advantage of speed, but software encryption is less secure than hardware encryption
Moreover, local data encryption and non-national secret algorithms based on foreign encryption chips do not comply with our country's password management policy for special occasions, and may also leave hidden hidden backdoor hidden dangers
Local data encryption requires a password verification process to increase the encryption level

Abstract

The invention discloses an intelligent password key with a local data encryption function. The intelligent password key comprises an encryption chip, a storage chip connected with the encryption chip, a power circuit, a connecting interface and a peripheral device, wherein the encryption chip is a microprocessor integrating a processor, input and output ports and a memory; the large-capacity storage chip is an NAND Flash chip, is provided with an NAND Flash controller and is connected with an external Flash to finish local data encryption storage; the power circuit is connected with a main control chip and the large-capacity memory, and monitors and provides a stable power supply; the connecting interface is connected with a local computer; and the peripheral device comprises an LED indication lamp and is connected with the encryption chip to indicate a working state of a USB Key. Compared with the prior art, the intelligent password key with the local data encryption function can serve as an encryption / decryption hardware key to encrypt / decrypt mass data of a PC end; and only a same encryption U disk can be used for encrypting / decrypting local data, so that the security is improved and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an intelligent cipher key with strong practicability and a local data encryption function. Background technique [0002] The rapid acceleration of the informatization process and the rapid development of e-commerce and e-government have also brought about various information security issues, increased use of smart password keys, and increased demand for security application functions. [0003] Now there are USBKey designs based on various encryption chips, but their functions are single, and the encryption chips are not fully utilized. For users of smart password keys, they often have high requirements for the security of their local data on their computers, and they have the need for local data encryption. Common local data encryption using software encryption has the advantage of speed, but software encryption is less secure than hardware encryption. Moreover, lo...
