These characteristics includes but not limited to decentralisation, traceability, security, transparency, immutability, non-repudiation, etc. There has been an increase in the body of knowledge in relation to the convergence of DLTs and IoTs. This paper examines how DLTs can enhance the security of resource-constrained IoT devices, which have limitations that prevent the implementation of traditional security measures like encryption due to size and computational power. This paper consolidates existing research by comparing techniques, technologies used, and results achieved over the years. Finally, the research identifies knowledge gaps for future exploration.FulltextenResource ConstrainedIoT DevicesDistributed Ledger TechnologiesDLTsSecurityCyber ResilientConference Presentationn/a
