Summary: [EME] Improvements to the secure proof of key release
protocol
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Media Elements
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: jer.noble at apple.com
After conversations with clients, change the informal protocol used to generate SPoKR messages to the following:
session = keys.createSession('mime', initData);
...
session.close()
This will result in a new keymessage, the contents of which is the SPoKR blob for that session.
The client will acknowledge receipt of the blob by calling:
session.update('acknowledge');
This will remove the session from the persistent store.
Additionally, outside of an existing storage, a client can ask for all outstanding SPoKR entries by creating a session like the following:
session = keys.createSession('keyrelease', certData);
This will result in a new keymessage, the contents of the first SPoKR blob in the persistent store.
The client will acknowledge receipt of the blob by calling:
session.update('acknowledge');
This will remove the session from the persistent store.
