Verifying Outsourced Computation in an Edge Computing Marketplace
Machine Learning & Applications, 2022 An edge computing marketplace could enable IoT devices (Outsourcers) to outsource computation to any participating node (Contractors) in their proximity. In return, these nodes receive a reward for providing computation resources. In this work, we propose a scheme that verifies the integrity of arbitrary deterministic functions in the presence of both ...

Outsourcing Private RAM Computation [PDF]
2014 IEEE 55th Annual Symposium on Foundations of Computer Science, 2014 We construct the first schemes that allow a client to privately outsource arbitrary program executions to a remote server while ensuring that: (I) the client's work is small and essentially independent of the complexity of the computation being outsourced, and (II) the server's work is only proportional to the run-time of the computation on a random ...

Algorithms for Outsourcing Pairing Computation [PDF]
, 2015 We address the question of how a computationally limited device may outsource pairing computation in cryptography to another, potentially malicious, but much more computationally powerful device. We introduce two new efficient protocols for securely outsourcing pairing computations to an untrusted helper.

Verifiable delegation of computation on outsourced data [PDF]
Proceedings of the 2013 ACM SIGSAC conference on Computer & communications security - CCS '13, 2013 We address the problem in which a client stores a large amount of data with an untrusted server in such a way that, at any moment, the client can ask the server to compute a function on some portion of its outsourced data. In this scenario, the client must be able to efficiently verify the correctness of the result despite no longer knowing the inputs ...

A Comprehensive Survey on Secure Outsourced Computation and Its Applications
IEEE Access, 2019 With the ever-increasing requirement of storage and computation resources, it is unrealistic for local devices (with limited sources) to implement large-scale data processing.

Secure outsourcing of scientific computations [PDF]
, 2002 We investigate the outsourcing of numerical and scientific computations using the following framework: A customer who needs computations done but lacks the computational resources (computing power, appropriate software, or programming expertise) to do these locally would like to use an external agent to perform these computations. This currently arises

Practical Secure Computation Outsourcing [PDF]
ACM Computing Surveys, 2018 The rapid development of cloud computing promotes a wide deployment of data and computation outsourcing to cloud service providers by resource-limited entities. Based on a pay-per-use model, a client without enough computational power can easily outsource large-scale computational tasks to a cloud. Nonetheless, the issue of security and privacy becomes

Optimal Contracts for Outsourced Computation [PDF]
, 2014 While expensive cryptographically verifiable computation aims at defeating malicious agents, many civil purposes of outsourced computation tolerate a weaker notion of security, i.e., “lazy-but-honest” contractors. Targeting this type of agents, we develop optimal contracts for outsourcing of computational tasks via appropriate use of rewards ...

Privacy-preserving trajectory similarity computation method
Tongxin xuebao, 2022 To tackle privacy concerns on user information leakage in trajectory outsourcing services, a privacy-preserving trajectory similarity computation (pTSC) method was proposed.A trajectory outsourcing service provider was enabled to store encrypted ...
