On the soundness of authenticate-then-encrypt: formalizing the malleability of symmetric encryption
A communication channel from an honest sender A to an honest receiver B can be described as a system with three interfaces labeled A, B, and E (the adversary), respectively, where...

Non-Malleable Non-Interactive Zero Knowledge and Adaptive Chosen-Ciphertext Security
We introduce the notion of non-malleable noninteractive zero-knowledge (NIZK) proof systems. We show how to transform any ordinary NIZK proof system into one that has strong non-m...

Homomorphic encryption from codes
We propose a new homomorphic encryption scheme based on the hardness of decoding under independent random noise from certain affine families of codes. Unlike in previous latticeba...

New Public Key Cryptosystems Based on the Dependent-RSA Problems
Since the Diffie-Hellman paper, asymmetric encryption has been a very important topic, and furthermore ever well studied. However, between the efficiency of RSA and the security of...

On the Security of ElGamal Based Encryption
The ElGamal encryption scheme has been proposed several years ago and is one of the few probabilistic encryption schemes. However, its security has never been concretely proven bas...
