Title : A Signature based Source Address Validation Method for IPv6 Edge Network

Today's Internet is suffering from reflection-type DoS/DDoS attacks,
such as TCP SYN flood, Smurf attack, DNS reflection, etc. These
attacks often rely on the IP source address spoofing. Current source
address spoofing prevention methods have a coarse granularity, and
the attackers can still in some cases launch reflection-type DoS/DDos
attacks or other attacks while being difficult to trace. Aiming to
solve this problem, this document proposes a fine-granularity source
address spoofing prevention method, which can prevent the attackers
from forging source addresses that belong to the same edge network to
send packets to somewhere outside the IPv6 edge network. The
proposed method includes source address authentication using session
key and hash digest algorithms and replay attack prevention by
combining a sequence number method with a timestamp method.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
