Securing M2M communication in Smart Cities

With the extensive use of different devices in smart cities the problems related to information security increases. Random nonce plays a vital role in communication security. A random nonce is used to generate the seeds randomly in various cryptographic applications to improve security measures. There are various alternative approaches for the generation of random nonce which are based on different cryptographic parameters. Researchers found that less power consumption implementation is preferable in a smart city environment. The devices under smart city environment have limited processing capability and storage capacity. To handle these challenges, many works are going on for reducing power consumption while generating random nonce for M2M communication. In this paper, authors are going to use the concept of light-weight cryptography to develop a new method for a random nonce generation. The focus of lightweight cryptography is to come up with such an algorithm that should be small enough to be suitable for constrained devices used in smart cities.
