Ckks security
WebTheir main observation is that a decryption result in approximate homomorphic encryption, such as for the Cheon-Kim-Kim-Song (CKKS) scheme, leaks information about the LWE noise in the approximation error. This noise can be … WebCKKS is an approximate homomorphic encryption scheme. It's possible that the error incurred during CKKS encryption and homomorphic operations is too great. By running the plaintext and ciphertext computations in parallel, HIT can compare the results after each step and help the developer understand where the computation is failing.
