In many content distribution systems it is important both to restrict access to content to authorized users and to protect the identities of these users. We discover that current s...
A family of novel broadcast encryption schemes based on probabilistic key pre-distribution are proposed, that enable multiple sources to broadcast secrets, without the use of asymm...
Abstract. Broadcast encryption provides a convenient method to distribute digital content to subscribers over an insecure broadcast channel. Traitor tracing is needed because some ...
Motivated by the need to outsource file storage to untrusted clouds while still permitting limited use of that data by third parties, we present practical protocols by which a cli...
We propose PASTE, the first differentially private aggregation algorithms for distributed time-series data that offer good practical utility without any trusted server. PASTE add...
