1.  Pervasive Monitoring Is a Widespread Attack on Privacy

   Pervasive Monitoring (PM) is widespread (and often covert)
   surveillance through intrusive gathering of protocol artefacts,
   including application content, or protocol metadata such as headers.
   Active or passive wiretaps and traffic analysis, (e.g., correlation,
   timing or measuring packet sizes), or subverting the cryptographic
   keys used to secure protocols can also be used as part of pervasive
   monitoring.  PM is distinguished by being indiscriminate and very
   large scale, rather than by introducing new types of technical
   compromise.

   The IETF community's technical assessment is that PM is an attack on
   the privacy of Internet users and organisations.  The IETF community
   has expressed strong agreement that PM is an attack that needs to be
   mitigated where possible, via the design of protocols that make PM
   significantly more expensive or infeasible.  Pervasive monitoring was
   discussed at the technical plenary of the November 2013 IETF meeting
   [IETF88Plenary] and then through extensive exchanges on IETF mailing
   lists.  This document records the IETF community's consensus and
   establishes the technical nature of PM.

   The term "attack" is used here in a technical sense that differs
   somewhat from common English usage.  In common English usage, an
   attack is an aggressive action perpetrated by an opponent, intended
   to enforce the opponent's will on the attacked party.  The term is
   used here to refer to behavior that subverts the intent of
   communicating parties without the agreement of those parties.  An
   attack may change the content of the communication, record the
   content or external characteristics of the communication, or through
   correlation with other communication events, reveal information the
   parties did not intend to be revealed.  It may also have other
   effects that similarly subvert the intent of a communicator.
   [RFC4949] contains a more complete definition for the term "attack".
   We also use the term in the singular here, even though PM in reality
   may consist of a multifaceted set of coordinated attacks.

   In particular, the term "attack", used technically, implies nothing
   about the motivation of the actor mounting the attack.  The
   motivation for PM can range from non-targeted nation-state
   surveillance, to legal but privacy-unfriendly purposes by commercial
   enterprises, to illegal actions by criminals.  The same techniques to
   achieve PM can be used regardless of motivation.  Thus, we cannot
   defend against the most nefarious actors while allowing monitoring by
   other actors no matter how benevolent some might consider them to be,
   since the actions required of the attacker are indistinguishable from
   other attacks.  The motivation for PM is, therefore, not relevant for
   how PM is mitigated in IETF protocols.
