IETF-66, Montreal, July 2006MSEC WG meeting9 Differences w.r.t. previous version  This version aims to be self-sufficient this I-D is a full specification of the TESLA BB contradicts what we explained at IETF65... e.g. added section 3 (upper delay bound calculation)  Corrects several errors some of them pointed by Ran (thanks!) too long to be presented here...  Proposes new formats “bootstrap info msg”, “direct time synchro response”  But some open points remain... (see the I-D)
