N2 - Encryption schemes that support computation on encrypted data are useful in constructing efficient and intuitively simple cryptographic protocols. However, the approach was previously limited to stand-alone and/or honest-but-curious security. In this work, we apply recent results on "non-malleable homomorphic encryption" to construct new protocols with Universally Composable security against active corruption, for certain interesting tasks. Also, we use our techniques to develop non-malleable homomorphic encryption that can handle homomorphic operations involving more than one ciphertext.
