The ElGamal encryption scheme has been proposed several years ago and is one of the few probabilistic encryption schemes. However, its security has never been concretely proven bas...
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 ...
Voting schemes that provide receipt-freeness prevent voters from proving their cast vote, and hence thwart vote-buying and coercion. We analyze the security of the multi-authority ...
We provide new constructions of Leakage-Resilient IdentityBased Encryption systems (IBE) in the Standard model. We apply a hash proof technique in the existing IBE schemes of Bone...

Recently Cash, Kiltz, and Shoup [20] showed a variant of the Cramer-Shoup (CS) public key encryption (PKE) scheme [21] whose chosen-ciphertext (CCA) security relies on the computa...
