| Summary: | Wireless sensor network services rely on two elements, secure communication. and symmetric key
distribution. As \VSN use svtnnmetric key crvptographv to protect data confidentiality, each sensor
node has to keep a copy olthe secret key to be used in encryption decryption process. 'I he secret
key can he sent wired or wireless. but wire solution is impassible especially in remote areas, while
current wireless solutions have either coveraw)e or cost issues or they require a lone implementation
time. Most studies try to 1111(s1o lutions for remote WSN network reachability by using solutions
like satellite connections. others turn out to use other wireless solutions to create point -to-point
connection. But such solutions lack durability in had weather or require a long time and effort in
addition to high cost to setup. This research will solve the issue ofsending secret key securely to
\VSN nodes in remote areas using commercial I'M stations. Since \V'SN node lacks processing
power, memory and energy capacity. l[Iliptic Curve ('rv}ptographv (F(C) will be used to encrypt
the secret key, as it has Cast computational time and smaller key size that can be transmitted easily
through FM radio. The encrypted spread has simple NOR encryption before modulating it to the
SO kl Iz. then it is embedded in the commercial FM band and broadcasted using commercial FM
stations, to hide the key within the FM band. This research seeks to solve key management issues
by providing multi-layers 01' security, to make certain that key is delivered without being snilied
or compromised. Through the implementation. we have tested that the technique being tested is
successlül in sending the secret key to \VSN base station. |
