Dear Börje and all,

On Access Control for heterogeneous groups (evaluation draft 05):

On the discussion of access control one approach that I think we
should add is the broadcast encryption based approach we proposed in
ICN 2013
(https://scholar.google.com/citations?view_op=view_citation&hl=en&user=KJPGePAAAAAJ&citation_for_view=KJPGePAAAAAJ:RHpTSmoSYBkC).

In this model, the content is encrypted and cached in the
network. To decrypt the content, a legitimate client (who possesses a
secret share calculated by Shamir's secret sharing scheme) receives the
enabling block (a metadata that is attached to the content) and extracts
the decryption key (by employing Lagrangian polynomial interpolation).
This model provides a nice way to revoke a client (replace the revoked
user's share with one of the available shares in the enabling block).

We also have a more comprehensive extended version in submission. Here
is the link to the document in arXiv: http://arxiv.org/abs/1603.03501.

I believe it is important for us to mention several approaches to show
that the community has thought on multiple lines. 		

With best regards,
 -Jay
