Web15 de mai. de 2024 · Almost all (modern) public-key schemes are presented in that way: with all the other parameters as functions of the security parameter $\lambda$. So, it is not exclusive to FHE schemes. And even if a scheme is not presented in this way, we may reason in the same way the paper did in order to obtain a security parameter. Webleveled homomorphic encryption scheme. The scheme in question claimed to withstand precisely such attacks, and was the only scheme of its kind to do so at the time. This part of the thesis culminates with Article III, which is an overview article on the IND-CCA1 security of all acknowledged homomorphic encryption schemes.
