There are a variety of Type-c data cables on the market. If you buy one, you will probably buy a cottage data cable. How to identify true and false? We all know that Apple data cable is encrypted and authenticated to identify true and false. In fact, Type-c data cable also has encryption authentication. Recently, the non-profit organization USB Developer Forum announced the Type-c certification specification. The software protocol can be Type- c The product builds a safety line to ensure that the product will not be damaged when it is charged using a non-compatible USB-C cable.
The USB Type-c certification specification shows that USB-IF will establish an internal certificate communication verification mechanism for each standard Type-c data line, charger, and device. The certificate uses 128-bit encryption to prevent cracking. When used, the device will verify the digital certificate in the Type-c data line, and determine whether it meets the relevant technical and security standards by confirming the power supply and other related information. If the verification fails, it means that the Type-c data line cannot be Use on the device.
Although the addition of hardware encryption verification will increase the design and manufacturing cost of Type-c data cable, the Type-c data lines currently available on the market can be said to be languid and easily cause damage to user equipment. Therefore, in the long run, only This is more secure.
