Abstract: While multi-key homomorphic encryption (MKHE) ensures privacy in federated learning (FL) by encrypting model updates, its requirement for aggregate ciphertext decryption and dropout handling ...

I'm getting the following error when I try to decrypt a password using your code, do you have any idea what the issue could be. The password i'm trying to decrypt is ...

OpenSSH has joined the high-stakes fight to protect data from quantum computers. The latest version of the widely used encryption and connectivity tool has been fitted with new features to prevent ...

I have been trying to apply a refresh/bootstrap operation on a ciphertext after a MulRelin operation using CKKS. Decrypting the resulting ciphertext returns completely incorrect values. E.g.

Abstract: In the last few decades, ciphertext-policy attribute-based encryption (CP-ABE) technology has attracted great interest, since it can provide fine-grained, flexible, and access control for ...
