Abstract

   This document describes the privacy issues associated with the
   Discovery of Agents, Workloads, and Named Entities (DAWN).  It
   provides general observations about typical current privacy practices
   in similar domains like, DNS, HTTP, and in general privacy in
   information retrieval.

1.  Introduction

   [I-D.akhavain-moussa-dawn-problem-statement] defines the problem
   space how AI-related entities discover and interact with one another
   across distributed ecosystems.  In particular, it focuses on defining
   the requirements for a standardized discovery substrate that allows
   entities to find one another based on attributes like skills,
   capabilities, policies,communication methods, and collaborate
   dynamically.

   In such a context, privacy is one of the hardest problems in entities
   discovery because the act of discovery itself can leak sensitive
   information.  When an entity searches for another entity, model,
   dataset, or compute resource, the query may reveal sensitive intent.
   For instance, a medical AI agent querying oncology datasets may
   reveal information about user health, or a company agent searching
   for GPU clusters before a product launch may reveal business

   strategy.  This may lead to privacy risks like surveillance of
   organizational behavior, users/enterprise profiling correlation
   attacks.

   This document focuses on the privacy risks associated to the action
   of entities discovery, i.e., how to protect the privacy of the entity
   performing the discovery so there is no information leakage.  It
   provides an threat analysis following the guidelines in [RFC6973].

   Published entity properties attributes, such as capabilities,
   endpoints, availability, geographic location, etc., may be also
   sensitive information.  Entities' published information should be
   controlled by their operators; privacy considerations about published
   information will discussed in future revision of this document.

   Private communication among entities should be part of the
   communication protocol itself, hence considered out of the scope of
   this document.

2.  Requirements Notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

3.  Definitions of Terms

   This document assumes familiarity with the terminology defined in
   [I-D.farrel-dawn-terminology]:

   *  Attributes

   *  Discoverable Object

   *  Discovery

   *  Discovery Mechanism

   *  Entity

   *  Minimum Discoverable Information

4.  Applicability Scope

   [RFC6973] clearly states that privacy should be included into
   protocols from the design phase, not afterwards.  This is especially
   true in open and cross-domain ecosystems.  As such any discovery
   protocol designed in the context of DAWN should natively include
   mechanisms to provide privacy protection.  However, the use of such
   mechanisms may be relaxed in specific contexts, like for instance
   closed ecosystems.  A closed ecosystem is an environment where
   discovery, communication, identity, orchestration, and capability
   advertisement are restricted to a single vendor, platform,
   enterprise, or tightly controlled federation.  Example of such
   ecosystems, may be internal coding assistants, HR workflow agents,
   finance analysis agents, procurement bots, security automation
   agents.  In such tightly controlled and closed environments privacy
   requirements might be less strict and privacy protection can be
   relaxed.  Yet, it is important to understand that privacy protection
   should be maintained by these closed environments when interfacing
   with other entities outside the local domain.

5.  Privacy Threat Analysis

   [RFC6973] provides guidelines about privacy in Internet protocols.
   It also introduces privacy related terminology and it provides a
   structured framework for analyzing privacy threats in Internet
   protocols.  Many of the privacy issues emerging in entities
   discovery, map directly onto the privacy concepts identified in
   [RFC6973].  As such the following subsections go through the the
   privacy threats identified in [RFC6973] and describe how they relate
   to DAWN.  The subsections assume that the reader is familiar with
   [RFC6973].

5.1.  Combined Security-Privacy Threats

5.1.1.  Surveillance

   Surveillance consists in observing communications or interactions
   over time.  In a discovery infrastructure a malicious observer can
   see which agents query which capabilities, organizational interests,
   workload patterns, operational behavior.  Discovery substrates become
   surveillance points unless privacy protections are built in.

Internet-Draft                DAWN Privacy                      May 2026

5.1.2.  Stored Data Compromise

   Stored protocol data becomes a privacy risk if not adequately
   protected.  Discovery systems may store query logs, interaction
   histories, and other type of metadata, that may reveal usage
   patterns, workflows, enterprise operations.  Hence, stores data
   should be minimized and protected.

5.1.3.  Intrusion

   TBD

5.1.4.  Misattribution

   TBD

5.2.  Privacy-Specific Threats

5.2.1.  Correlation

   Linking multiple interactions like repeated discovery queries, agent
   identifiers, capability searches, may lead to identify users or
   entities behavior.

5.2.2.  Identification

   Protocols may expose identity unnecessarily.  In the context of DAWN,
   discovery may expose organization names, infrastructure ownership,
   operator identity.  Even capability metadata may uniquely fingerprint
   an entity.  Discovery should avoid identity exposure beyond
   operational necessity.

5.2.3.  Secondary Use

   TBD

5.2.4.  Disclosure

   TBD

5.2.5.  Exclusion

   TBD

6.  Similarities with Domain Name System (DNS) privacy protection

   Discussion about DNS privacy and similarities with DAWN from a
   privacy perspective.

7.  Privacy vs Auditability

   TBD

8.  [RFC6973] Guidelines Compliance

   [RFC6973] provides guidance in the form of a questionnaire about a
   protocol being designed.

   [Replies to RFC6973 questionnaire to be added.]

9.  Threats Mitigation

   [RFC6973] defines three categories of relevant mitigations, namely
   (1) data minimization, (2) user participation, and (3) security.
   They apply also in the context of DAWN.

9.1.  Technological building blocks

   Some privacy-enhancing technologies can be used at an advantage in
   improving the privacy of entities discovery.  Among those
   technologies, Private Information Retrieval can be used at a benefit
   in the development of privacy-preserving discovery protocols.

   Private Information Retrieval (or PIR) [PIR95] is a technology
   initially developed in the database realm.  It is used by users to
   retrieve information stored in a server while hiding the exact
   retrieved information from the server hosting it.  As PIR schemes
   have gained efficiency and become usable at scale in a distributed
   setting, their use in DAWN to prevent registrars or entities hosting
   capacities of interest to retrieve information about requesters'
   interests and activities.  In investigating those developments,
   specific care need to be taken about the ability of academic PIR
   schemes to cope with the scale at which DAWN needs to operate.

   [Future revision to have DAWN-specific mitigation categories]

10.  IANA Considerations

   This document does not require any IANA action.

11.  Security Considerations

   TBD.
