1 Activities in Internet Engineering Task Force (IETF) for Internet Trust

To discuss a trust and knowledge ICT infrastructure, it is required to review a data lifecycle – its production,
process and consumption. Therefore, it is important to deal with trust issues focusing on Internet. For this
purpose, this clause introduces IETF’s activities on trust to identify trends and main issues from perspective
of Internet.
In IETF, currently 11 working groups (WG) are dealing with issues on trust.
– DNSOP (Domain Name System Operations)

– DNSSEC (Domain Name System Security Extensions)
– DNSExt (Domain Name System Extensions)
– NEA (Network Endpoint Assessment)
– OAUTH (Web Authorization Protocol)
– HTTPbis (HyperText Transfer Protocol)

– WPKOPS (Web Public Key Infrastructure Operations)
– ECRIT (Emergency Context Resolution with Internet Technologies)
– SDNRG (Software Defined Networking Research Group)
– ICNRG (Information Centric Networking Research Group)\
– SIDR (Secure Inter-Domain Routing)
