Abstract:
CoAP unicast and group communication for low-power and lossy networks
(LLNs) are foreseen to be used for building and lighting control
systems. Although unicast CoAP communication mandates DTLS for
security, no similar existing security mechanisms exist to secure
CoAP group communication. The draft, DTLS multicast security
[I-D.keoh-dice-multicast-security], proposes a solution based on
reusing the DTLS record layer to also secure CoAP group
communication. Although that solution has advantages in terms of
code reuse, it does not ensure source authentication within the
group. This draft presents alternative CoAP group communication
security solutions based on public key cryptographic signatures to
also ensure source authentication within the group.
