The increasing centralization of networked services places user data at considerable risk. For example, many users store email on remote servers rather than on their local disk. D...

We present the first hierarchical identity based encryption (HIBE) system that has full security for more than a constant number of levels. In all prior HIBE systems in the literat...
We study cryptographic modeling and encryption-based design techniques for guaranteeing privacy of data that is first stored in some type of computer memory and then deleted. We ...
We propose a new notion of secure multiparty computation aided by a computationally-powerful but untrusted “cloud” server. In this notion that we call on-the-fly multiparty c...
In this paper we describe new secure personalization schemes using proxy cryptography. We first introduce the context of a large scale smart card application such as an electronic ...
