Abstract

To minimize the risks associated with pervasive surveillance, it is necessary for the Internet technical community to address the vulnerabilities exploited in the attacks documented in [RFC7258] and the threats described in [RFC7624]. The goal of this document is to address a common design pattern that emerges from the increase in encryption: explicit association of metadata that would previously have been inferred from the plaintext protocol.

               Design Considerations for Metadata Insertion

Abstract

   The IAB published RFC 7624 in response to several revelations of    pervasive attacks on Internet communications.  This document    considers the implications of protocol designs that associate    metadata with encrypted flows.  In particular, it asserts that    designs that share metadata only by explicit actions at the host are    preferable to designs in which middleboxes insert metadata.
