Web1.2.1 Chimeric FHE Our starting point is the hybrid FHE scheme recently introduced by Brakerski et al. [BDGM19], which we recall in the following. The objective of their work is to build an FHE scheme with best possible rate (in an asymptotic sense) by leveraging the fact that most LWE-based FHE scheme admit an e cient linear noisy decryption.
