UBITECH attended the IETF 123 Physical Meeting, where the team presented its vision on extending Trusted Path Routing, a key step towards enhancing the security and resilience of modern networks.
The goal was to motivate the need towards incrementing the static nature of the current secure routing mechanisms, already established in the TPR Draft, with runtime capabilities continuously assessing node- and data-centric trust as an integral routing metric. This exposes a traffic engineering process where path establishment policies are considered in an optimized combination with the available {network, trust, energy} resources and carefully drive the subsequent network management decisions.
To advance this vision, CASTOR’s unique runtime attestation functionalities, wrapped as part of its Trust Network Exposure Layer, were put forth for integration into the extended draft-rats-runtime-tpr-00. This work aims to be a cornerstone for inter- and intra-domain trust semantics and coordination.
