ePrint Report: Verifiable Multi-Client Functional Encryption for Inner Product

Dinh Duy Nguyen, Duong Hieu Phan, David Pointcheval

Joint computation on encrypted data is becoming increasingly crucial with the rise of cloud computing. In theory, multi-party computation (MPC) allows for secure computation, but it is often impractical due to intensive interactions between users. In recent years, the development of multi-client functional encryption (MCFE) has made it possible to perform joint computation on private inputs, without any interaction. Well-settled solutions for linear …
