Abstract. We propose new instantiations of chosen-ciphertext secure identitybased encryption schemes with wildcards (WIBE). Our schemes outperform all existing alternatives in term...

As such, public-key encryption with keyword search (a.k.a PEKS or searchable encryption) does not allow the recipient to decrypt keywords i.e. encryption is not invertible. This pa...
We give the first proof of security for an identity-based encryption scheme in the quantum random oracle model. This is the first proof of security for any scheme in this model ...
Abstract. This paper addresses the security of symmetric cryptosystems in the blockwise adversarial model. At Crypto 2002, Joux, Martinet and Valette have proposed a new kind of at...
Abstract. The concept of timed-released encryption with pre-open capability (TRE-PC) was introduced by Hwang, Yum and Lee. In a TREPC scheme, a message is encrypted in such a way t...
