Query: Securing Content Sharing over ICN   The emerging Information-Centric Networking (ICN) paradigm is expected to
facilitate content sharing among users. ICN will make it easy for users to
appoint storage nodes, in various network locations, perhaps owned or
controlled by them, where shared content can be stored and disseminated from.
These storage nodes should be (somewhat) trusted since not only they have (some
level of) access to user shared content, but they should also properly enforce
access control. Traditional forms of encryption introduce significant overhead
when it comes to sharing content with large and dynamic groups of users. To
this end, proxy re-encryption provides a convenient solution. In this paper, we
use Identity-Based Proxy Re-Encryption (IB-PRE) to provide confidentiality and
access control for content items shared over ICN, realizing secure content
distribution among dynamic sets of users. In contrast to similar IB-PRE based
solutions, our design allows each user to generate the system parameters and
the secret keys required by the underlay encryption scheme using their own
Private Key Generator, therefore, our approach does not suffer from the key
escrow problem. Moreover, our design further relaxes the trust requirements on
the storage nodes by preventing them from sharing usable content with
unauthorized users. Finally, our scheme does not require out-of-band secret key
distribution.
