Call for Participation in HTTPS in Local Network Community Group

The HTTPS in Local Network Community Group has been launched:

The HTTPS in Local Network Community Group (CG) explores the manner of secure communication between browsers and server-capable devices in local network such as set-top boxes, network attached storages, etc. We propose that this Community Group clarify requirements for browsers and devices in issuing valid certificates and establishment of HTTPS and WebSocket connections over TLS and incubate relevant specifications of APIs and/or network protocols.

This work has four primary purposes:

  • Improve security and privacy of communication between browsers and server-capable devices.
  • Enable web applications in secure contexts to communicate with server-capable devices in local network via XMLHttpRequest, Fetch API, and WebSocket.
  • Enable service discovery mechanisms to advertise existence of TLS-enabled server-capable devices.
  • Encourage adoption and implementation of the specification by browser vendors and device manufacturers.

Given wider support and adequate stability, we plan to migrate the proposals
generated in this Community Group to an appropriate standards track, for
example the IETF Standards Track or a W3C Working Group, for further
contributions and formal standardization.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2017-02-03 by Tomoyuki Shimizu. The following people supported its creation: Tomoyuki Shimizu, Daisuke Ajitomi, Yoshiro Yoneya, Junichi Hashimoto, Tatsuya Igarashi. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
