What's the use of encryption dog? What's it for.

I looked at it in the encyclopedia, but I didn't understand what it was for. What's the use of it.

Encryption dog generally refers to the encryption lock, is a computer encryption device.

Encryption lock is a kind of intelligent tool with software protection function for software developers. It contains a device installed in the parallel port of computer or

USB

The hardware on the interface, and a set of interface software and tool software suitable for various languages.

The encryption lock realizes encryption by exchanging data with the encryption lock in the process of software execution. The embedded MCU circuit (also known as CPU) makes the encryption lock have the ability of judgment and analysis, and enhances the active anti decryption ability.

The MCU in the encryption lock contains the algorithm software specially used for encryption. After the software is written into the MCU, it cannot be read out. In this way, the encryption lock hardware can not be copied.

Extended information:

1. With the increasing upgrading of decryption technology, higher requirements are put forward for the security of encryption lock. The traditional intelligent programmable encryption lock advocates "code chip transplantation" - hollowing out the matrix of the protected program by points, which is safe in theory, but not in practice

2. Compared with the traditional encryption scheme, a new type of dongle has appeared in the market. Synaptics announced a new micro USB dongle scheme, which can be inserted into any notebook to make it have fingerprint identification function immediately
