Query: Publicly Verifiable Outsourced Computation with a Key Distribution
  Centre   The combination of software-as-a-service and the increasing use of mobile
devices gives rise to a considerable difference in computational power between
servers and clients. Thus, there is a desire for clients to outsource the
evaluation of complex functions to a server and to be able to verify that the
resulting value is correct. Previous work in this area of Publicly Verifiable
Outsourced Computation (PVC) requires a costly pre-processing stage. However,
in many practical situations multiple clients will be interested in the same
set of core functions and will make use of the same servers. Thus, the
pre-processing phase may be performed many more times than is necessary. In
this paper we introduce a Key Distribution Center (KDC) that handles the
generation and distribution of the keys that are required to support PVC,
thereby eliminating this redundancy. We define a number of new security models
and functionalities that arise with the introduction of the KDC, and present a
construction of such a scheme built upon Key-Policy Attribute-based Encryption.
