above link is gateway to all wireless security document

In the leap process there are two keys

a) Session key ( unicast key )

b) broadcast key

Session key is independently generated by client and AP . It is important to note that this session key is dynamic in nature and this session timeout can be configured on the radius server ( 27 parameter )

Now broadcast key is static in nature . If you want to make is dynamic than on

Ap go to setup->Radio advance

You can turn on Bkey rotation here .

Now if you turn on Bkey rotation your wep client will break . Also keep in mind that when you enable leap either turn on Bkey rotation or define key 1 in slot Key1

I hope this helps
