“…In our previous conference paper, we pointed out the security weakness of the DHE protocol in the provision of security solution against threats such as man-in-the-middle attacks due to vulnerabilities in the protocol to authenticate participating nodes using their unique identifying features in block stream cipher [1].…”

“…This paper is an extension of work originally presented in the International Conference on Communications, Signal Processing and Networks/International Conference on Cyber Security and Internet-of-Things ICCSPN/ICSIoT. The relatively complex key schedule that Twofish cryptographic primitive supported together with the DHE provided an efficient and tamper-resistant security scheme for data exchange between nodes in IoT [1].…”

“…The key exchange protocol only supports secure sharing of session key and does not provide authentication of the source node for creating the message. Replay attacks, Man-in-the-middle attacks, Dictionary attacks, Key compromise impersonation attacks and ephemeral key compromise attacks are some of the vulnerabilities that DHE protocol suffers [1]. Cryptographic algorithms provide mechanisms for authentication using various approaches like digital signature schemes and public-key certificates.…”

Internet of Things provides the support for devices, people and things to collaborate in collecting, analyzing and sharing sensitive information from one device onto the other through the internet. The internet of things is thriving largely due to access, connectivity, artificial intelligence and machine learning approaches that it supports. The stability and enhanced speed of the internet is also attributable to the huge adoption rate that IoT continues to enjoy from Governments, industry and academia in recent times. The increased incidences of cyber-attacks on connected systems in recent times, has inspired the heightened efforts from Governments, industry practitioners and the research world towards improving existing approaches and the engineering of new innovative schemes of securing devices, the software or the platforms for the deployment of IoT. Security solution for Internet of things includes the use of secure ciphers and key exchange algorithms that ensures the provisioning of a security layer for the: devices or hardware, communication channels, cloud, and the life cycle management constituting the Internet of things. The use of key exchange algorithms in resilient cryptographic solution that have less computational requirements without compromising the security efficiency in the encryption of messages for IoT continues to be the preferred approach in securing messages in a node-node exchange of data. This paper aims at providing a cryptographic solution that uses a key exchange cryptographic primitive and a strong cipher in encrypting messages for exchange between nodes in an IoT. Towards achieving this goal, the Diffie-Hellman key exchange (DHE) protocol was used to provide a secure key exchange between the communicating nodes, whiles the Twofish block cipher was used in the encryption and decryption of messages, assuring the security, privacy and integrity of messages in a node-node IoT data exchange. The cryptographic solution has a high throughput.
