Main Article Content
Abstract
The growth of smart agriculture has enhanced the food production efficiency and sustainability. However, it has also expanded the attack surface to different cyber security threats. The inherent limitations in smart agriculture devices and their environment limit the adoption of cyber security measures. Deployment of Public Key Infrastructure (PKI) in smart agriculture devices can enhance the security of the smart agriculture systems. However, traditional PKI frameworks are built for implementation in systems with large computational power. This limits their adoption in smart agriculture systems. To address these challenges, a transition toward Concise Binary Object Representation (CBOR) and the CBOR Object Signing and Encryption (COSE) standard is enhanced the security of smart agriculture devices. The proposed framework provides a scalable, binary-first security roadmap that can be practically implemented to safeguard the smart agriculture systems in resource-constrained environments.
