Generic and Practical Key Establishment from Lattice
In this work, we abstract some key ingredients in previous key establishment and public-key encryption schemes from LWE and its variants. Specifically, we explicitly formalize the building tool, referred to as...

Order-Revealing Encryption: File-Injection Attack and Forward Security
Order-preserving encryption (OPE) and order-revealing encryption (ORE) are among the core ingredients for encrypted databases (EDBs). In this work, we study the leakage of OPE and ORE and their forward security.

Identity-Based Encryption Secure against Selective Opening Chosen-Ciphertext Attack
Security against selective opening attack (SOA) requires that in a multi-user setting, even if an adversary has access to all ciphertexts from users, and adaptively corrupts some fraction of the users by expos...

All-but-One Dual Projective Hashing and Its Applications
Recently, Wee (EUROCRYPT’12) introduced the notion of dual projective hashing as an extension of the Cramer-Shoup projective hashing, with a simple construction of lossy trapdoor functions, and a simple constr...

A New Framework for Privacy of RFID Path Authentication
RFID-based path authentication enables supply chain managers to verify the exact path that a tag has taken. In this paper, we introduce a new oracle Move that models a tag’s movement along a designed or an arbitr...

On the Security of a Bidirectional Proxy Re-encryption Scheme from PKC 2010
In ACM CCS 2007, Canetti and Hohenberger left an interesting open problem of how to construct a chosen-ciphertext secure proxy re-encryption (PRE) scheme without bilinear maps. This is a rather interesting pro...

Hierarchical Identity-Based Chameleon Hash and Its Applications
At ACNS 2008, Canard et al. introduced the notion of trapdoor sanitizable signature (TSS) based on identity-based chameleon hash (IBCH). Trapdoor sanitizable signatures allow the signer of a message to delegat...

Deniable Internet Key Exchange
In this work, we develop a family of non-malleable and deniable Diffie-Hellman key-exchange (DHKE) protocols, named deniable Internet key-exchange (DIKE). The newly developed DIKE protocols are of conceptual clar...

Generic and Practical Resettable Zero-Knowledge in the Bare Public-Key Model
We present a generic construction for constant-round concurrsound resettable zero-knowledge (rZK-CS) arguments for \(\mathcal{NP}\) ...
