Key-Privacy in Public-Key Encryption
We consider a novel security requirement of encryption schemes that we call “key-privacy” or “anonymity”. It asks that an eavesdropper in possession of a ciphertext not be ...

On the Minimal Assumptions of Group Signature Schemes
Abstract. One of the central lines of cryptographic research is identifying the weakest assumptions required for the construction of secure primitives. In the context of group sign...

Plaintext Simulatability
We propose a new security class, called plaintext-simulatability, defined over the public-key encryption schemes. The notion of plaintext simulatability (denoted PS) is similar to ...

Encryption Schemes Secure against Chosen-Ciphertext Selective Opening Attacks
Imagine many small devices send data to a single receiver, encrypted using the receiver’s public key. Assume an adversary that has the power to adaptively corrupt a subset of the...
