Abstract: Cloud users can use a TPA to verify data integrity with public verification. However, quantum computer breakthroughs suggest cloud applications. Most public verification schemes use conventional hardness assumptions, which are vulnerable to future quantum…

Abstract: DNA marking, genomic sequencing, and genetic disease prediction use DNA similarity search. Users are also storing DNA data on the cloud to save money as data grows rapidly. DNA data is sensitive, so the…

Abstract: This projects considers delay requirements when scheduling virtual machines (VMs) in a queueing cloud computing system with stochastic arrivals of heterogeneous jobs. In such a cloud computing system, delay-optimal VM scheduling is a multi-resource…

Abstract: Globally distributed datacenters replicate service data for more cloud services to improve quality and reliability. Replication generates many one-to-many bulk data transfers over inter-datacenter networks. These data transfers must be completed within deadlines to…

Abstract: Cloud computing is mature, but security and privacy concerns remain. Cryptographic solutions to secure cloud services and protect cloud data are still being researched. This paper critiques the wide range of cryptographic schemes used…

Abstract: Security and privacy concerns prevent enterprises and users from adopting cloud computing and reaping its cost savings and business agility. Cloud services’ heterogeneity and dynamicity increase attack surfaces, causing these concerns. Effective and flexible…

Abstract: Mobile edge computing (MEC) has gained popularity due to its low latency, location awareness, and mobility support, which offsets cloud computing’s drawbacks. However, QoS-aware recommendation and composition of MEC services may fail due to…

Abstract: Combining atomic services into a value-added service may help cloud users meet their diverse needs. Existing studies rarely consider concurrency of composite service requests among multiple users and thus lack an incentive mechanism to…

Abstract: For resource-constrained clients to save money, outsourcing complex, intensive tasks to public cloud vendors is inevitable. Public cloud vendors are usually untrustworthy. They may accidentally leak data, misuse data, compromise privacy, or corrupt computational…

Abstract: Trajectory segmentation segments sequential trajectory. These segments form various applications. Trajectory segment indexing, storage, and query require a system framework. A distributed solution is suggested for segments larger than a single processing node. This…

Abstract: IoT has been a hot topic lately. In IoT, blockchain is trusted, reliable, and decentralized. The blockchain’s drawbacks prevent it from being a generic IoT platform. IoT nodes lack computing and networking resources. Unfortunately,…

Abstract: Performance tuning improves system performance and reduces cloud computing resources needed to support an application. Cloud performance tuning must be automated due to the growing number of parameters and system complexity. Modern tuning methods…
