Algebraic Attack on FHE-Friendly Cipher HERA Using Multiple Collisions

Algebraic Attack on FHE-Friendly Cipher HERA Using Multiple Collisions

Fully homomorphic encryption (FHE) is an advanced cryptography technique to allow computations (i.e., addition and multiplication) over encrypted data. After years of effort, the performance of FHE has been significantly improved and it has moved from theory to practice. The transciphering framewor...
