In relation to smart city planning and management, processing huge amounts of generated data and execution of non-lightweight cryptographic algorithms on resource constraint devices at disposal, is the primary focus of researchers today. To enable secure exchange of data between cloud networks and mobile devices, in particular smart hand held devices, this paper presents Blockchain based approach that disperses a public/free key to save it on a block within a Blockchain. The proposed system generates public-private key pair to encrypt data digitally to allow data communication. This empowers communication devices to encipher data using keys stored in the Blockchain i.e. the public key. Generated cipher text can be decrypted/deciphered only with the respective private keys, meaning that only the communicating devices can obtain their own plain text in a data exchange process. Smart mobile employed in smart city can then encipher the data using the keys and store them on the cloud. The proposed system is able to decrease the number of overheads that relate to key generation, key delivery and key storage whilst providing solutions for data processing, information exchange and data over-collection, respectively. Thus, the study proposes a robust and secure solution to exchange keys and secure data communication based on Blockchain technology.
