Abstract: Edge computing processes data locally instead of in the cloud. Blockchain can secure edge computing data. An edge server’s data storage request should be a blockchain transaction with the data owner’s signature. A blockchain…
Abstract: Service-Based Systems (SBSs) and Software as a Service (SaaS) are emerging as cloud computing dominates software engineering. Cloud services handle many client requests. If many users need multiple Quality of Service (QoS) attributes, selecting…
Abstract: Mobile apps’ rapid growth brings performance and energy issues. However, application-level code sharing is limited. This paper designs, implements, and deploys mobile device transparent machine code sharing. SnapCode allows machine code sharing across many…
Abstract: I/O virtualization performance is limited by hypervisor intervention in the virtual I/O event path due to costly VM exits. Hardware-based Posted-Interrupt (PI) technology emerged due to the failures of software solutions to virtual interrupt…
Abstract: Electricity prices vary by time and location. Cloud workflow applications transmit geo-distributed data between heterogeneous servers in intra- and inter-data centers. When scheduling workflow tasks to heterogeneous servers in cloud data centers, varying electricity…
Abstract: Energy costs dominate cloud computing today. Energy-aware task scheduling is crucial. Heterogeneous clusters can save energy by scheduling tasks based on deadlines, data locality, and resource utilization. Task list construction, scheduling, and slot list…
Abstract: Cloud computing is increasingly used to host massive datasets. Existing research suggests encrypting sensitive data before outsourcing and using Searchable Symmetric Encryption (SSE) for keyword-based searches over the ciphertexts since the cloud service provider…
Abstract: SDN and NFV make cloud Service Function Chain (SFC) deployment efficient and flexible. However, without knowledge of underlying network configurations, overlay networks cannot efficiently chain Virtualized Network Functions (VNFs). Many deterministic VNF placement and…
Abstract: In delegated computing, encrypted signal processing can protect sensitive signals from untrusted cloud servers and unauthorized users without affecting the accuracy of large-volume signal analysis and processing. Most approaches use Paillier’s public key additively…
Abstract: Cloud VMs are susceptible to performance issues due to colocated tenants’ unpredictable contention for shared physical resources. In public clouds, provider-centric solutions like careful co-scheduling and VM migration require customer VM profiling, which is…
Abstract: Dumb nodes degrade sensor-cloud system performance. This article considers dumb nodes in the sensor-cloud platform and proposes a dynamic pricing scheme. The literature on sensor-cloud pricing assumes a perfect environment with working sensor nodes….
Abstract: Searching sensitive data securely in cloud storage is difficult. Searchable encryption secures data without compromising privacy or usability. Scholars study public-key encryption with keyword search (PEKS), an important searchable encryption branch. Most PEKS schemes…
