ePrint Report: X-Cipher: Achieving Data Resiliency in Homomorphic Ciphertexts

Adam Caulfield, Nabiha Raza, Peizhao Hu

Homomorphic encryption (HE) allows for computations on encrypted data without requiring decryption. HE is commonly applied to outsource computation on private data. Due to the additional risks caused by data outsourcing, the ability to recover from losses
is essential, but doing so on data encrypted under an HE scheme introduces additional challenges for recovery and usability. This work introduces X-Cipher, which aims to make HE …
