Smart Contracts for Incentivized Outsourcing of Computation
, 2022 Outsourcing computation allows a resource limited client to expand its computational capabilities by outsourcing computation to other computing nodes or clouds. A basic requirement of outsourcing is providing assurance that the computation result is correct.

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 ...

Delegation of computation with verification outsourcing
Proceedings of the 2013 ACM symposium on Principles of distributed computing, 2013 In the Cloud Computing paradigm, a user often reduces financial, personnel, and computational burdens by outsourcing computation and other IT services to a professional service provider. However, to be able to assure the correctness of the result, the user still needs to perform the verification himself.

Verifiable outsourced computation over encrypted data [PDF]
Information Sciences, 2019 Abstract In recent years, cloud computing has become the most popular and promising service platform. A cloud user can outsource its heavy computation overhead to a cloud service provider (CSP) and let the CSP make the computation instead. In order to guarantee the correctness of the outsourced processing (e.g., machine learning and data ...

Outsourcing Computing of Large Matrix Jordan Decomposition
Mathematical Problems in Engineering, 2019 The Jordan decomposition of matrix is a typical scientific and engineering computational task, but such computation involves enormous computing resources for large matrices, which is burdensome for the resource‐limited clients. Cloud computing enables computational resource‐limited clients to economically outsource such problems to the cloud server ...

BeeKeeper 2.0: Confidential Blockchain-Enabled IoT System with Fully Homomorphic Computation
Sensors, 2018 Blockchain-enabled Internet of Things (IoT) systems have received extensive attention from academia and industry. Most previous constructions face the risk of leaking sensitive information since the servers can obtain plaintext data from the devices.

Incentivized Outsourced Computation Resistant to Malicious Contractors [PDF]
IEEE Transactions on Dependable and Secure Computing, 2017 With the rise of Internet computing, outsourcing difficult computational tasks became an important need. Yet, once the computation is outsourced, the job owner loses control, and hence it is crucial to provide guarantees against malicious actions of the contractors involved.
