Wireless communication trends are getting changed day by day. Internet of Things (IoT) is the latest running trend of wireless communication. IoT applications are very demanding in present and many more will come in the near future. IoT applications are running in insure medium i.e. Internet. Security and Privacy are the major challenges in IoT implementation. In conventional cryptography, one dedicated secret key is stored in volatile or non-volatile memory. Which has been used by the processor for every encryption or decryption Even though system is turned off the secret key is remain present in memory and can be access by attacker using side channel attacks. Thus, the traditional approaches to key storage are not favoured. Physically Unclonable function (PuF) can resolve such issues. Instead of using the same dedicated secrete key PuF can generate unique bits for every operation. Here we are presenting a brief survey of security challenges opportunities of PuF for IoT applications.
