Resumo(s)
Securing wireless communication is significant
for privacy and confidentiality of sensing data in CyberPhysical
Systems (CPS). However, due to broadcast nature
of radio channels, disseminating sensory data is vulnerable to
eavesdropping and message modification. Generating secret
keys by extracting the shared randomness in a wireless fading
channel is a promising way to improve the communication security.
In this poster, we present a novel secret key generation
protocol for securing real-time data dissemination in CPS,
where the sensor nodes cooperatively generate a shared key
by estimating the quantized fading channel randomness. A 2-
hop wireless sensor network testbed is built and preliminary
experimental results show that the quantization intervals and
distance between the nodes lead to a secret bit mismatch.
