Abstract. This exposition paper suggests a new low-bandwidth publickey encryption paradigm. The construction turns a weak form of key privacy into message privacy as follows: let E...
In this paper, we propose a notion of threshold tag-based encryption schemes that simplifies the notion of threshold identity-based encryption schemes, and we show a conversion fro...
In this paper we consider two security notions related to Identity Based Encryption: Key-insulated public key encryption, introduced by Dodis, Katz, Xu and Yung; and Timed-Release ...

The main purpose of this paper is to show that public key encryption can be secure against the "encryption emulation" attack (on the sender's encryption) by computat...
Abstract. We first propose the notion of universally anonymizable publickey encryption. Suppose that we have the encrypted data made with the same security parameter, and that the...
