IAB Statement on Internet Confidentiality
In 1996, the IAB and IESG recognized that the growth of the Internet
depended on users having confidence that the network would protect
their private information. RFC 1984 documented this need. Since that
time, we have seen evidence that the capabilities and activities of
attackers are greater and more pervasive than previously known. The IAB
now believes it is important for protocol designers, developers, and
operators to make encryption the norm for Internet traffic. Encryption
should be authenticated where possible, but even protocols providing
confidentiality without authentication are useful in the face of
pervasive surveillance as described in RFC 7258.
Newly designed protocols should prefer encryption to cleartext operation.
There may be exceptions to this default, but it is important to recognize
that protocols do not operate in isolation. Information leaked by one
protocol can be made part of a more substantial body of information
by cross-correlation of traffic observation. There are protocols which
may as a result require encryption on the Internet even when it would
not be a requirement for that protocol operating in isolation.
We recommend that encryption be deployed throughout the protocol stack
since there is not a single place within the stack where all kinds of
communication can be protected.
The IAB urges protocol designers to design for confidential operation by
default. We strongly encourage developers to include encryption in their
implementations, and to make them encrypted by default. We similarly
encourage network and service operators to deploy encryption where it is
not yet deployed, and we urge firewall policy administrators to permit
encrypted traffic.
We believe that each of these changes will help restore the trust users
must have in the Internet. We acknowledge that this will take time and
trouble, though we believe recent successes in content delivery networks,
messaging, and Internet application deployments demonstrate the
feasibility of this migration. We also acknowledge that many network
operations activities today, from traffic management and intrusion
detection to spam prevention and policy enforcement, assume access to
cleartext payload. For many of these activities there are no solutions
yet, but the IAB will work with those affected to foster development of
new approaches for these activities which allow us to move to an Internet
where traffic is confidential by default.
