Introduction

Internation law defines a number of emblems as indicators of special protections or handling. These emblems signal protection for people, objects, and locations. As technology advances and new capabilities become available, the goal has emerged of complementing physical emblems with digital ones. The Digital Emblem (DIEM) working group will focus on the developing capabilities that augment the existing emblem and extend their reach into the digital realm.

Problem Statement

Physical emblems have served a number of key functions over hundreds of years. The design/use of those physical emblems were limited by the available resources and capabilities during the time of their inceptions. As technology advances and newer capabilities become available, it is beneficial to examine limitations with existing emblems and identify enhancements going forward.

Some of those enhancements include:

  • Authenticity - Emblems currently do not carry any type of attestation to the validity of the emblem, but this is possible in a digital emblem.
  • Visibility - Emblems are not always visible to observing parties, but digital emblems can observed in a myriad of ways.
  • Mis-use - Emblems do not provide sufficient context to indicate the validity of their observed use.
  • Management - Emblems cannot currently be revoked to address abuse, compromise, or expiry.

Goals

The preliminary problem statement documents a number of potential use cases. The working group will explore those use cases to identify the functional capabilities that are common to a large subset of those use cases. The working group will:

  • Collaborate with external stakeholders on the development of any additional requirements.
  • Coordinate with other IETF working groups on the re-use of existing efforts to satisfy DIEM requirmeents.
  • Develop new capabilities to satisfy requirements not covered by existing IETF technologies.

Program of Work

Documents produced by the working group will address the following topics.

  1. Identification of representative use cases embracing the range of potential needs.
  2. Collection and analysis of requirements.
  3. Analysis of the security needs for digital emblems.
  4. Development of solutions that satisfy requirements and security needs for targe use cases.
