We should concern people, respect character and try to communicate with students instead of single input; we must make full use of modern devices, and we must use all kinds of disseminative method instead of preaching. We should pay attention to the establishment of covert course, and we must transform our teaching from in-class teaching to teaching of multi-direction influences. We must strengthen the research of moral training tactics and make our moral training method artistic and skillful.

By introducing XOR operation and one-way function chains to group key management schemes based on the keys tree, a new group key management scheme based on the keys tree, XOR operation and one-way function chains is proposed. Initialization, member adding and member evicting operations are introduced. The new scheme is compared with three other group key management schemes which are based on the keys tree:SKDC, LKH, and OFT. As far as transmission, computation and storage costs are concerned, the performance of the new group key management scheme is the best.
