Non-malleable encryption with proofs of plaintext knowledge and applications to voting
anonymity applications election schemes
2019/1/16
Non-malleable asymmetric encryption schemes which prove plaintext knowledge are sufficient for secrecy in some domains. For example, ballot secrecy in voting. In these domains, some applications deriv...
Improved, Black-Box, Non-Malleable Encryption from Semantic Security
public-key cryptography non-malleable encrytpion
2016/12/10
We give a new black-box transformation from any semantically secure encryption scheme into
a non-malleable one which has a better rate than the best previous work of Coretti et al. (TCC
2016-A). We ...
A Black-Box Construction of Non-Malleable Encryption from Semantically Secure Encryption
Non-Malleable Encryption Semantically Secure Encryption
2016/7/22
We show how to transform any semantically secure encryption scheme into a non-malleable one, with a black-box construction that achieves a quasi-linear blow-up in the size of the ciphertext. This impr...
Non-Malleable Encryption: Simpler, Shorter, Stronger

We answer all three questions in the positive. First, we improve the rate in the construction of Choi et al. by a factor O(k), where k is the security parameter. Still, encrypting a message of size O(...
Non-Malleable Encryption: Equivalence between Two Notions, and an Indistinguishability-Based Characterization
Asymmetric encryption Non-malleability Indistinguishability
2008/12/3
We prove the equivalence of two definitions of non-malleable encryption, one based on the
simulation approach of Dolev, Dwork and Naor [6] and the other based on the comparison approach
of Bellare, ...
