Bounded CCA2-Secure Non-Malleable Encryption
Under an adaptive chosen ciphertext attack (CCA2), the security of an encryption scheme must hold against adversaries that have access to a decryption oracle. We consider a weakening of CCA2 security, wherein security need only hold against adversaries making an a-priori bounded number of querie...
