We show that chosen plaintext attacks (CPA) security is equivalent to chosen ciphertext attacks (CCA) security for key-dependent message (KDM) security. Concretely, we show how to construct a public-k...
In this note, we show that a strong notion of KDM security cannot be obtained by any encryption scheme in the auxiliary input setting, assuming Learning With Errors (LWE) and one-way permutations. The...
For encryption schemes, key dependent message (KDM) security requires that ciphertexts preserve secrecy even when the encrypt messages may depend on the secret keys. While KDM security has been extens...
To date, all constructions in the standard model (i.e., without random oracles) of Bounded Key-Dependent Message (KDM) secure (or even just circularly-secure) encryption schemes rely on specific assum...
We present new frameworks for constructing public-key encryption schemes satisfying key-dependent message (KDM) security and that yield efficient, universally composable oblivious transfer (OT) proto...
We study the natural question of how well suited the hybrid encryption paradigm is in the context of key-dependent message (KDM) attacks. We prove that if a key derivation function (KDF) is used in be...
