- Abstract
- In this paper, we introduce a
security
vulnerability
of Bluetooth Low Energy(BLE)
and propose
a
n
improved
security
method to solve it
.
BLE
is used to
transmit
and receive data between nodes
such as
sensors, wearable devices in
the
Internet of
T
hings
(IoT) environment. However, there is a possibility that
an encryption key
for
communicating between
nodes
can be
cracked
because of the security vulnerability
of BLE.
The s
ecurity
vulnerability
of BLE is that the
length of
the
Temporary Key (TK)
to generate
the
encryption key
is
too short.
It is a
fatal problem in
terms of a data security.
We describe how
an attacke
r
can crack the
encryption key through the vulnerability.
To solve this problem, we propose an improved
security method that increases the
length
of
the
TK. In
the conventional BLE, the encryption key can be
cracked within 20 sec
onds
. But,
it may take
600,
000,000,000 years
when
the proposed method is
used.
Therefore, the proposed method
can ensure
that
it is infeasible to crack the encryption key.
