  2. 2. Copyright © 2004-2014 Lepidum Co. Ltd. All rights reserved.https://lepidum.co.jp/ arcmedia BoF  Top-level Archive Media Type (ARCMEDIA)  non WG-forming BoFのつもりで → WG設立?  アーカイブメディアに対応するトップレベ ルmedia-typeを作るべきか?  draft-seantek-kerwin-arcmedia-type-00  例: archive/tar  動機 (Sean Leonard)  application/tarを作ろうとして application/zipを発見 IETF91報告会2014/12/19 3
  3. 3. Copyright © 2004-2014 Lepidum Co. Ltd. All rights reserved.https://lepidum.co.jp/ arcmedia 問題点  ユースケース  まずどんなsubtypeがあるのかリストしてから  UIの統一なども考えるのか  ファイル名の国際化, subpath  tar, tar|bzip2の両方がないと署名検証で失敗  multipartとの使い分け  appsawgで議論するか、新しいWGを作るか  Barry Leibaは新WGの方向  ML: arcmedia IETF91報告会2014/12/19 4
  4. 4. Copyright © 2004-2014 Lepidum Co. Ltd. All rights reserved.https://lepidum.co.jp/ mcic bar BoF  Multiparty Content Integrity and Confidentiality  TLSはe2e point-to-pointである。もっと他の場合も扱いた い  同一のTLSセッションに3者以上の参加者  Thomas Fossati案: TLSに3rd-partyパブリックキーを導 入。交信の一部をプロキシでも見えるようにする  HTTP headersをintermediaryにも見えるように送る、 bodyはendにしか見えないように、など  多くの問題が指摘された  compromiseできる、AEADでは難しい、shared-keyを多くのユー ザ間で共有するのはよくない、など IETF91報告会2014/12/19 5

All rights reserved.https://lepidum.co.jp/ mcic  use casesCaching  Content inspection  video pacing/optimizations  TLS keys for CDN  多すぎる。wikiなどに集める → 問題定義、解決案、 privacy/security impacなどを検討  proxyの話に終始していたが、single-flow内での security level分離が必要なのかという問が大事  TLSをbreakすることが目的ではないので注意  ML: mcic IETF91報告会2014/12/19 6
