Escrow-free encryption supporting cryptographic workflow
Since Boneh and Franklin published their seminal paper on identity based encryption (IBE) using the Weil pairing , there has been a great deal of interest in cryptographic primitiv...

Direct chosen ciphertext security from identity-based techniques
We describe a new encryption technique that is secure in the standard model against adaptive chosen ciphertext (CCA2) attacks. We base our method on two very efficient Identity-Ba...

Towards Black-Box Accountable Authority IBE with Short Ciphertexts and Private Keys
At Crypto'07, Goyal introduced the concept of Accountable Authority Identity-Based Encryption as a convenient tool to reduce the amount of trust in authorities in Identity-Bas...

Searchable Encryption Revisited: Consistency Properties, Relation to Anonymous IBE, and Extensions
We identify and fill some gaps with regard to consistency (the extent to which false positives are produced) for public-key encryption with keyword search (PEKS), providing new de...

A New Paradigm of Hybrid Encryption Scheme
In this paper, we show that a key encapsulation mechanism (KEM) does not have to be IND-CCA secure in the construction of hybrid encryption schemes, as was previously believed. Tha...
