USB-key is a novel secure storage product of Lingqiang by using advanced encryption technology and specific application software, combing with data storage, certificate authentication and individual application.
USB-key can provide complete network security function and support highly secure large file storage. It adopts homemade security chip specific for smart card as control chip, combines with specific operating system independently developed by Lingqiang. It supports RSA key pair generation in chip, data signature and authentication, data encryption and decryption, algorithm downloading, and applies to highly secure electronic identity authentication and data transfer. Large-capacity storage media inside can realize encrypted data storage to ensure high security of file.
Advantage of USB-key is driver free. It is based on standard BOT protocol and applies to Windows 2000 or above operating system. After user gets USB-key, he needn't install driver, which completely removes the problem of installation failure. After it is connected to computer, system can automatically identify removable disk, and also identify a CD-ROM which is an inside USB-key product to store various tool.
Supported by specific software, USB-key will be divided into two areas, encrypted storage area and common area. Size of two sub-areas can be adjusted. Encrypted sub-area is protected by password. After password verification passes, it just can be used. Encryption and decryption of file and data are transparent for user.
