  Potential capacity of processors is enhancing rapidly which leads to the
increase of computational ability of the adversary. As a result, the required
key size for conventional encryption techniques is growing everyday for complex
unbreakable security communication systems. The Public Key Cryptography (PKC)
techniques which use larger keys cannot be fitted in tiny resource constrained
Wireless of Things (WoT) devices. Some Symmetric Key Cryptosystems (SKC) use
smaller keys, which can be fitted in the tiny devices. But in large networks
where the number of nodes is in the order of 103, the memory constraint does
not allow the system to do so. The existing secure data communication in
insecure medium uses various conventional encryption methods like Public Key
Cryptography (PKC) and Symmetric Key Cryptosystems (SKC). Generally, modern
encryption methods need huge processing power, memory and time. Also in some
cases, Key Pre-distribution System (KPS) is used among different communicating
devices. With the growing need for larger key size in the conventional secure
communication system, the existing resources in the communicating devices
suffer from resource starvation. Hence, the need of a novel mechanism for
secure communication is inevitable. But the existing secure communication
mechanisms like PKC, SKC or KPS do not ensure elimination of resource
starvation issue in tiny devices during communication. In these existing
conventional mechanisms, the plain text is generally converted into cipher text
with greater size than the plain text at the device level, which leads to
resource starvation. At the time of transmission, the cipher text at the device
end requires more bandwidth than the plain text which puts bandwidth overhead
on the broadcast channel (BC).
