Simulation-Sound NIZK Proofs for a Practical Language and Constant Size Group Signatures
Non-interactive zero-knowledge proofs play an essential role in many cryptographic protocols. We suggest several NIZK proof systems based on prime order groups with a bilinear map...

Confidential Signatures and Deterministic Signcryption
Encrypt-and-sign, where one encrypts and signs a message in parallel, is usually not recommended for confidential message transmission. The reason is that the signature typically l...

Threshold Cryptosystems Secure against Chosen-Ciphertext Attacks
Abstract. Semantic security against chosen-ciphertext attacks (INDCCA) is widely believed as the correct security level for public-key encryption scheme. On the other hand, it is o...

Wildcarded Identity-Based Encryption
In this paper we introduce a new primitive called identity-based encryption with wildcards, or WIBE for short. It allows a sender to encrypt messages to a whole range of receivers ...

Outsider-Anonymous Broadcast Encryption with Sublinear Ciphertexts
Abstract. In the standard setting of broadcast encryption, information about the receivers is transmitted as part of the ciphertext. In several broadcast scenarios, however, the id...
