浙大中控加密狗廠家講講加密狗的使用辦法。
The dongle is a software encryption product that combines software and hardware plugged into the parallel port of the computer. The hardware encryption lock, FreeEIM, commonly known as the "dongle", generally has dozens or hundreds of bytes of nonvolatile storage space for reading and writing. The manufacturer of the central control dongle at Zhejiang University talks about the use of the dongle.
1、如果是前臺加密狗，在收到我公司的加密狗后，前臺用戶要在前臺“下載加密狗驅動程序”處下載加密狗驅動程序。安裝完畢，登陸進去后在“安全設置”里點擊“綁定加密狗”，這樣每次登陸時前臺客戶都須要使用加密狗。如果是后臺加密狗，后臺客戶就要跟我公司客服人員聯系，我們會把驅動程序發給您安裝、在系統中設置綁定后您即可使用，同樣每次登陸您都須使用加密狗。
1. If it is a front desk dongle, after receiving the dongle from our company, the front desk user should download the dongle driver at the "Download dongle driver" position of the front desk. After the installation, click "Bind dongle" in the "Security Settings" after logging in, so that the foreground customers need to use the dongle every time they log in. If it is a background dongle, the background customer should contact our customer service personnel. We will send the driver to you for installation, set the binding in the system, and then you can use it. Similarly, you must use the dongle every time you log in.
2、把加密狗插上電腦USB接口，然后登陸，當您登陸進入系統前臺或后臺后，就須立刻把加密狗拔掉，加密狗的作業只在您登陸的時候起到驗證作用，當您登陸完畢后，它就不在重復作業。進入系統操作完畢以后，須及時安全退出平臺，下次重新正確登陸。
2. Plug the dongle into the USB interface of the computer, and then log in. When you log in to the foreground or background of the system, you must immediately unplug the dongle. The dongle's operation only verifies when you log in. When you log in, it will not repeat the operation. After entering the system, you must exit the platform safely in time and log in again correctly next time.
3、如果您沒有及時的把加密狗拔掉，非法人員還是可以利用不正當的手段進入您的系統，遠程操縱您的機器，實際上您的加密狗形同虛設。
3. If you do not unplug the dongle in time, illegal people can still use improper means to enter your system and remotely manipulate your machine. In fact, your dongle is nothing.
4、加密狗妥善保管，防止丟失，不得借予他人使用，。若不慎遺失，盡快在后臺取消加密狗綁定，丟失的加密狗就不可再使用。仍想再次使用新加密狗請與我們聯系，我們會重新為您定做加密狗，您再次綁定后即可使用。
4. The dongle shall be kept properly to prevent loss and shall not be lent to others,. If it is accidentally lost, cancel the binding of the dongle in the background as soon as possible, and the lost dongle can no longer be used. If you still want to use the new dongle again, please contact us. We will customize the dongle for you again, and you can use it after you bind it again.
That's all for the use of dongles. If you have any questions, please come to our website http://www.869h.cn Get in touch!
