An Efficient Dynamic Key Generation Architecture for Distributed Wireless Networks

Distributed wireless networks are capable of delivering solutions for countless engineering and viable applications. The sensor nodes of these wireless networks tolerate tons of limitations namely low computation capability, secured data transmission, tiny memory, fractional energy resources, etc. Within this environment any sensor node can initiate the communication over a period, hence it is imperative to enhance the reliability of data which is communicated. In a secured communication, diverse numbers of hardware devices are employed for sharing the information wirelessly. Therefore, the dynamic keys guarantee the secureness of data between the diverse numbers of user devices. Here the manuscript deals about a method of generating dynamic keys for secure communication in a distributed environment that cannot be predicted or cloned by the previous values. The dynamic keys are generated by employing a hybrid hardware of PRNG (Pseudo-Random Number Generator) and PUF (Physical Unclonable Function). A hardware platform is preferred to produce the randomly unclonable dynamic keys.
