2013 Proceedings of the Twenty-Fourth ACM Symposium on Operating Systems Principles - SOSP '13  
Pantry composes proof-based verifiable computation with untrusted storage: the client expresses its computation in terms of digests that attest to state, and verifiably outsources that computation.  ...  Using Pantry, we extend verifiability to MapReduce jobs, simple database queries, and interactions with private state.  ...  Acknowledgments We first learned of the folklore approach to verifying computations with state from motivating comments by Yuval Ishai and an anonymous NDSS 2012 reviewer.  ...

Charalampos Papamanthou, Elaine Shi, Roberto Tamassia
2013 Lecture Notes in Computer Science  
In the SCC model, a trusted source outsources a function f to an untrusted server, along with a public key for that function (to be used during verification).  ...  We introduce Signatures of Correct Computation (SCC), a new model for verifying dynamic computations in cloud settings.  ...  This work was supported by Intel through the ISTC for Secure Computing, by the National Science Foundation under grants CCF-0424422, 0842695, 0808617 and CNS-1228485, by the Air Force Office of Scientific  ...

How to Delegate and Verify in Public: Verifiable Computation from Attribute-Based Encryption [chapter]

Bryan Parno, Mariana Raykova, Vinod Vaikuntanathan
2012 Lecture Notes in Computer Science  
The wide variety of small, computationally weak devices, and the growing number of computationally intensive tasks makes the delegation of computation to large data centers a desirable solution.  ...  However, computation outsourcing is useful only when the returned result can be trusted, which makes verifiable computation (VC) a must for such scenarios.  ...  Public Verifiable Computation Verifiable computation schemes enable a client to outsource the computation of a function F to an untrusted worker, and verify the correctness of the results returned by the  ...

A Framework for Outsourcing of Secure Computation

Thomas P. Jakobsen, Jesper Buus Nielsen, Claudio Orlandi
2014 Proceedings of the 6th edition of the ACM Workshop on Cloud Computing Security - CCSW '14  
We study the problem of how to efficiently outsource a sensitive computation on secret inputs to a number of untrusted workers, under the assumption that at least one worker is honest.  ...  The clients want to delegate a secure computation of f (x1, . . . , xn) to a set of untrusted workers W1, . . . , Wm.  ...  A notable example is the case of verifiable delegation of computation [GGP10,PHGR13,BSCG + 13, BFR13, BFR13] where one (or more) computationally bounded clients want to perform a computation on an untrusted  ...
