Verifiable computation with access control in cloud computing

Journal of Supercomputing, 2013
With the tremendous growth of cloud computing, verifiable computation has been firstly formalized by Gennaro et al. and then studied widely to provide integrity guarantees in the outsourced computation. However, existing verifiable computation protocols either work in the secret key setting or in the public key setting, namely, work either for single ...

Stateful Multi-client Verifiable Computation

Lecture Notes in Computer Science, 2018
This paper develops an asynchronous cryptographic protocol for outsourcing arbitrary stateful computation among multiple clients to an untrusted server, while guaranteeing integrity of the data. The clients communicate only with the server and merely store a short authenticator to ensure that the server does not cheat.

A Survey of Verifiable Computation

Mobile Networks and Applications, 2017
Internet of Things (IoT) has taken place to motivate various intelligent applications with the data collected by the things”. Meanwhile, Cloud computing offers an efficient and convenient way to store, process and analyze huge amount of data. Because a Cloud Service Provider (CSP) that is employed to store and process user private data is actually not ...

Batch Verifiable Computation with Public Verifiability for Outsourcing Polynomials and Matrix Computations

2016
In a verifiable computation VC scheme, a client asks a server to perform some outsourced computations, and the latter returns the results as its response. The results can be verified privately or publicly. Fiore and Gennaro CCS 2012 constructed publicly verifiable protocols for secure outsourcing polynomials and matrix computations.

Verifiable Outsourced Computation

Proceedings of the ACM Symposium on Principles of Distributed Computing, 2017
I will review recent (and not so recent) research on the topic of Verifiable Outsourced Computation. The problem of verifying the correctness of computations done by untrusted parties was a driving motivation behind some of the most celebrated results in Complexity Theory in the 90's, from Interactive Proofs to the PCP Theorem.

Verifiable Computation of Large Polynomials

2015
Due to the proliferation of powerful cloud service, verifiable computation, which makes a computationally weak client perform intensive computations possible through outsourcing tasks to a powerful server, is attracting increasing attention. The correctness of the returned result should be verified as the server may be not trusted. In this paper, we
