Chain-of-trust packet marking
Otávio Carpinteiro,
Universidade Federal de Itajubá –
Abstract:
The talk will focus on a new deterministic IPv6 traceback
method – chain-of-trust packet marking (CTPM) – which has
been developed by the Research Group on Systems and
Computer Engineering (GPESC) at the Federal University of
Itajuba (UNIFEI), Brazil. CTPM establishes a chain of trust
composed of the border routers of autonomous systems (ASes).
It makes use of a new IPv6 extension header – the traceback
extension header (TEH) – which extends the datagram size in
168 bytes at most. The TEH contains encrypted marks which
trace the path taken by each IPv6 datagram from its origin
to the destination. A few preliminary results will be
presented during the talk.
