We study the relationship among public-key encryption (PKE) satisfying indistinguishability against chosen plaintext attacks (IND-CPA security), that against chosen ciphertext attacks (IND-CCA securit...
We construct two identity-based encryption (IBE) schemes. The first one is IBE satisfying key dependent message (KDM) security for user secret keys. The second one is IBE satisfying simulation-based r...
In PKC 1999, Fujisaki and Okamoto showed how to convert any public key encryption (PKE) scheme secure against chosen plaintext attacks (CPA) to a PKE scheme which is secure against chosen ciphertext...
In this work, we prove the first \emph{generic} KDM amplification theorem which relies solely on the KDM security of the underlying scheme without making any other assumptions. Specifically, we show t...
We construct the first public-key encryption scheme that is proven secure (in the standard model, under standard assumptions) even when the attacker gets access to encryptions of arbitrary efficient...
Standard security notions for encryption schemes do not guarantee any security if the encrypted messages depend on the secret key. Yet it is exactly the stronger notion of security in the presence o...
