mDNS is predominant and lightweight protocol that is used to do service announcements/advertisements and discovery by the enterprise devices. mDNS is by definition multicast in nature and is UDP based non encrypted service announcement and discovery protocol. There are many security challenges for using mDNS as network service discovery protocol in enterprise IoT deployments. One such challenge is to avoid the MITM attacks (network service spoofing, forge the identity etc.,). Today there is neither infrastructure nor method built into the protocol to address the above limitations. Ideally the network should be intelligent to handle this scenario using the sophisticated methods. The techniques presented herein is to provide authenticated and secure Service Discovery in an enterprise deployment using the Holochain technology and provide secure service registration, service discovery, service transfer, service auditing and usage.
