WebCKKS explained, Part 3: Encryption and Decryption. Third part of the series CKKS explained where we see how to build an HE system from RLWE, implement encryption, decryption, addition and multiplication. … Webprocedure for CKKS has a large associated error, and, prior to this work, it was not possible to perform high precision computations in CKKS since bootstrapping would reduce the precision of the plaintext. Obtaining high precision bootstrapping of CKKS is particularly important since many applications of CKKS require high precision computation.
