-This protocol develops the idea of delegation of quantum computation to a server in a multi-party setting with guarantee for secrecy of both the data and the computation.
+This [https://arxiv.org/abs/1606.09200 example protocol] achieves the functionality of [[Secure Client- Server Delegated Computation|Delegation Quantum Computation]] to a server for multiple Clients with the guarantee that Server is unknown of any Clients' inputs/outpts/computation. This protocol is an extension of [[Preapre-and-Send Universal Blind Quantum Computation]] in the multiparty setting.
-It performs computation on encrypted data in the Measurement Based Quantum Computing framework.
-This protocol is a direct extension of '''Universal Blind Quantum Computation (to be linked)''' in the multiparty setting.

 The Protocol consists of 2 phases: Preparation phase and Computation phase.

 * '''Input qubits:''' For the input qubit states, each client one-time pads their qubit and uses secret sharing schemes to share the secret values with other clients. The honest behaviour for every client is enforced via the given protocol. The server then one-time pads them and measures the one-time padded qubits and announces the measurement values.
