Security USB KEY

Overview:

C*Core’s security USB KEY is a composite product of USB KEY and security USB, including two models: Secure USB KEY and large-capacity Security USB KEY. It can be widely used in various fields such as PKI authentication, digital signatures, data (real-time) encryption and decryption, and data secure storage.

Features:

USB KEY

The USB KEY, also known as the password key, is a secure carrier for digital certificates and private keys based on the Public Key Infrastructure (PKI). It provides 128K or 256K user space. Key pairs can be generated or imported within the USB KEY while the private key cannot be exported, ensuring the information security of the certificate owner. At the same time, it adopts dual authentication of "hardware + password", to ensure the legitimate use of digital certificates and private keys

Security USB

The Security USB has three default partitions (the number of partitions depends on the mass production scheme), which are ISO CD, general memory area, and secure memory area.

The ISO CD is used to place customer-defined programs, such as login tools, help documents, etc.

The general memory area is a universal memory area where data can be freely read and written.

The secure memory area is an encrypted area that can only be used after entering the password. If the password is entered incorrectly more than 6 times, a protection mechanism is activated, then both the security USB and the password key are locked.

The secure storage area can also be configured as a hidden storage area. The hidden area does not display a drive letter. There is no file system inside, and data in the hidden area can only be read and written through a specific interface library.
