In the face of an untrusted cloud infrastructure, outsourced data needs to be protected. Fully homomorphic encryption is one solution that also allows performing operations on outsourced data. However, the involved high overhead of today’s fully homomorphic encryption techniques outweigh cloud cost saving advantages, rendering it impractical. We present EPiC, a practical, efficient protocol for...

This study is focused on intraand inter-organizational communication managed by client organizations in outsourced information system development (ISD) projects. Previous research shows the importance of internal communication in an organization when it adopts an integrated IS. Outsourcing literature also notes the importance of managing communication and knowledge exchange with the vendor. How...

This study examines the moderating effect of buyer-supplier trust on the relationship between outsourced formal contracts and supplier delivery performance in the domain of public sector procurement. In so doing, we extend the paradigm that formal contracts and relational governance mechanism function as complements rather than substitutes. Using a cross sectional data from a survey of 612 staf...

Secure multiparty computation (SMC) offers a technique to preserve functionality and data privacy in mobile applications. Current protocols that make this costly cryptographic construction feasible on mobile devices securely outsource the bulk of the computation to a cloud provider. However, these outsourcing techniques are built on specific secure computation assumptions and tools, and applyin...
