Security Considerations in the IP-based Internet of Things
draft-garcia-core-security-05
Abstract
A direct interpretation of the Internet of Things concept refers to
the usage of standard Internet protocols to allow for human-to-thing
or thing-to-thing communication. Although the security needs are
well-recognized, it is still not fully clear how existing IP-based
security protocols can be applied to this new setting. This
Internet-Draft first provides an overview of security architecture,
its deployment model and general security needs in the context of the
lifecycle of a thing. Then, it presents challenges and requirements
for the successful roll-out of new applications and usage of standard
IP-based security protocols when applied to get a functional Internet
of Things.
Status of this Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
