Report from the IAB Workshop on
Managing Radio Networks in an Encrypted World (MaRNEW)
Abstract
The Internet Architecture Board (IAB) and GSM Association (GSMA) held
a joint workshop on Managing Radio Networks in an Encrypted World
(MaRNEW), on September 24-25, 2015. This workshop aimed to discuss
solutions for bandwidth optimization on mobile networks for encrypted
content, as current solutions rely on unencrypted content, which is
not indicative of the security needs of today's Internet users. The
workshop gathered IETF attendees, IAB members, and participants from
various organizations involved in the telecommunications industry
including original equipment manufacturers, content providers, and
mobile network operators.
The group discussed Internet encryption trends and deployment issues
identified within the IETF and the privacy needs of users that should
be adhered to. Solutions designed around sharing data from the
network to the endpoints and vice versa were then discussed; in
addition, issues experienced when using current transport-layer
protocols were also discussed. Content providers and Content
Delivery Networks (CDNs) gave their own views of their experiences
delivering their content with mobile network operators. Finally,
technical responses to regulation were discussed to help the
regulated industries relay the issues of impossible-to-implement or
bad-for-privacy technologies back to regulators.
A group of suggested solutions were devised, which will be discussed
in various IETF groups moving forward.
