In PKC 2012, a public key encryption based on new multivariate quadratic assumptions is proposed. The compactness and security of the algorithm illumined us in applying it in proxy re-encryption scheme. In this paper, a novel unidirectional PRE scheme (NMQ-PRE) is constructed based on new multivariate quadratic assumptions. The new scheme is a formal PRE scheme and compact in cryptographic protocols. By applying the nature property of multivariate quadratic assumptions, NMQ-PRE is proved chosendoi:10.4304/jcp.8.12.3238-3242 fatcat:dxeg33yykbdalixtxsnwwpfyee
