Product Description

The whole encryption system is composed of the encryption card and USB key. The main function of the encryption card is to actively encrypt any information comes into the hard drives (including the operating system, hard disk partition list, user programs, files, etc.), to ensure the whole hard disk is a cipher, after insert USB key, hard drive can be decrypted. This encryption product protects data through dynamically generated random numbers. Data processing, interface controller all implemented within FPGA, its reasonable system structure can guarantee the maximum system compatibility, the strongest encryption performance, while PC performance and usage mode will not be affected by using this product.

Product Features:

1)This product uses FPGA DNA serial number and anti-copy fuse technology, ensures every chip design is unique and prevents hardware copy.

2) The data is parallel processed within the FPGA, assembly line type, fast processing speed, does not affect the original computer use and performance.

3)All encrypted and decrypted data processing within the FPGA, completely put an end to their relevant communication monitoring, further improve the safety performance.

4)USB key safekeeping by the user, computer cannot be started without the key, cannot use the data in the hard disk either.

5)Adopted password length of 256 - bit AES algorithm (advanced encryption standard in the cryptography) and password length of 128 - bit SM4 national cipher algorithm for data encryption.

6)True random numbers are used as system authentication information generating source, dynamic authentication runs through the whole working process of the encryption system, avoid the risk of static authentication be cracked, to ensure the security of computer system and data as long as USB key in hand.

System Function

The principle diagram of the system function

Data that written into hard disk (including the operating system, hard disk partition list, user programs, documents, etc.) is encrypted by this product, when users read the data which decrypts at the same time. USB key serves as information using credentials in the process, it will not be able to enter the operating system and other raw data without USB key.
