On the security of RSA textbook signature scheme on Paillier ciphertext
Aleksejus Mihalkovich, Eligijus Sakalauskas · Lietuvos matematikos rinkinys · 2016
In this paper we consider Pailler encryption and RSA textbook signature. We show that due to valuable homomorphic property these algorithms can be used together to obtain a valid signature on a certain combination of ciphertexts. Our goal is to show that this combination of algorithms provide security against chosen plaintext and chosen ciphertext attacks.
