Looking at the above analysis, it is clear that the B protocol is due to a protocol, but in fact it is not so simple. B protocol requires hardware support, the ID value is not random assignment, but the track of the hardware tracking points, if the hardware can not meet this condition, then the B protocol can only be made into jokes.
