The
wormhole
attack
is
a
severe
attack
against
ad
hoc
routing
protocols
that
is
particularly
challenging
to
defend
against;
it
can
potentially
cripple
a
range
of
ad
hoc
network
routing
protocols.
In
the
wormhole
attack,
an
attacker
records
packets
(or
bits)
at
one
location
in
the
network,
tunnels
them
to
another
location,
and
retransmits
them
from
there
into
the
network.
Most
existing
ad
hoc
network
routing
protocols
that
lack
a
mechanism
to
defend
them
against
the
wormhole
attack
would
be
unable
to
ﬁnd
routes
longer
than
one
or
two
hops,
which
severely
disrupts
communication.
虫洞攻击是一个严重的攻击，路由协议，是特别具有挑战性，抵御;它可以削弱一系列网络路由协议。在虫洞攻击，攻击者记录数据包(或位)在同一地点的网络，隧道到另一个位置，并转发到网络。现有的大多数网络路由协议，缺乏一种机制来保护他们免受虫洞攻击将无法ﬁ钕路线长于1或2啤酒花，这严重破坏通信。If
a
wormhole
attacker
tunnels
all
packets
through
the
wormhole
honestly
and
reliably,
no
harm
is
done;
the
attacker
actually
provides
a
useful
service
in
connecting
the
network
more
efﬁciently.
However,
when
an
attacker
forwards
only
routing
control
messages,
this
attack
might
severely
disrupt
routing.
For
example,
when
used
against
an
on-demand
routing
protocol
such
as
DSR4
or
AODV,
a
powerful
application
of
the
wormhole
attack
can
be
mounted
by
tunneling
each
ROUTE
REQUEST
packet
directly
to
the
target
node
of
the
REQUEST.
This
attack
prevents
any
node
from
discovering
routes
more
than
two
hops
long.如果一个虫洞攻击隧道数据包通过虫洞诚实可靠，没有造成危害后果的;攻击者实际上提供了一个有用的服务，更有效地ﬁ连接网络。然而，当一个攻击者只转发路由控制消息，这次袭击可能严重破坏路由。例如，当使用一个路由协议如dsr4或路由协议，一个强大的应用虫洞攻击可以安装在隧道每个路由请求数据包直接到目标节点的请求。这种攻击可以防止任何节点发现路线超过2跳。Periodic
protocols
are
also
vulnerable
to
this
kind
of
attack.
For
example,
OLSR
and
TBRPF
use
HELLO
packets
for
neighbor
detection,
so
if
an
attacker
tunnels
to
B
all
HELLO
packets
transmitted
by
A
and
tunnels
to
A
all
HELLO
packets
transmitted
by
B,
then
A
and
B
will
believe
that
they
are
neighbors,
which
would
cause
the
routing
protocol
to
fail
to
ﬁnd
routes
when
they
aren’t
actually
neighbors.周期性的协议，也容易受到这类攻击。例如，路由和tbrpf使用包来检测为邻居，所以如果攻击者隧道都喂所传送的数据包和隧道到所有你好所传送的数据包，然后，会相信他们是邻居，这将导致路由协议未能ﬁ钕路线时，他们不实际上的邻居。The
wormhole
attack
is
also
dangerous
in
other
wireless
applications.
One
example
is
any
wireless
access
control
system
that
is
proximity
based,
such
as
wireless
car
keys
or
proximity-
and
token-based
access
control
systems
for
PCs.
In
such
systems,
an
attacker
could
relay
authentication
exchanges
to
gain
unauthorized
access.虫洞攻击也是危险的其他无线应用。一个例子是任何无线接入控制系统，是接近，如无线车钥匙或接近和象征性的访问控制系统的电脑。在这样的系统中，攻击者可以获得未经授权的访问认证交流继电器。Our
solution
to
the
wormhole
attack
is
packet
leashes.
We
consider
speciﬁcally
two
types
of
packet
leashes:
geographical
and
temporal.
The
main
idea
is
that
by
authenticating
either
an
extremely
precise
timestamp
or
location
information
combined
with
a
loose
timestamp,
a
receiver
can
determine
if
the
packet
has
traversed
an
unrealistic
distance
for
the
speciﬁc
network
technology
used.
Temporal
leashes
rely
on
extremely
precise
time
synchronization
and
timestamps
in
each
packet.
We
can
approximate
a
packet’s
travel
time
as
the
difference
between
the
receive
time
and
the
timestamp.
To
be
more
conservative,
however,
a
node
can
choose
to
add
the
maximum
time
synchronization
error,
assuming
that
the
sender’s
clock
might
be
faster
than
the
receiver’s.我们的解决方案的虫洞攻击数据包*。我们认为，特别地ﬁ类型分组的牵引:地理和时间。其主要思想是，通过认证的任何一个非常精确的时间戳或位置信息，结合一个松散的时间戳，接收器可以确定数据包已经走过一个不切实际的距离为ﬁ网络技术。时间约束依靠非常精确的时间同步，时间戳每个数据包。我们可以近似的数据包的旅行时间之间的差异的时间和收到的时间戳。更为保守，然而，一个节点可以选择添加最大时间同步误差，假设发送方的时钟可能是速度快于接收器的。
可以了吧!大哥
