Homomorphic approximation of non-linear activation functions using the CKKS cryptosystem of the OpenFHE library
Homomorphic computing can be viewed as the holy grail of encryption, as it allows evaluating computations on encrypted data. This enables perfect privacy for cloud applications, as a cloud provider handling user data never gets to see the data it is performing calculations on. Unfortunately, homomorphic cryptosystems c...
