Secure, Privacy-Preserving FPGA-Enabled Architectures for Big Data and Cloud Services: Theory, Methods, and Integrated Design Principles

Abstract

This article presents an original, integrative, and publication-ready examination of secure, privacy-preserving architectures that leverage Field-Programmable Gate Arrays (FPGAs) for big data processing and cloud services. Drawing strictly from the provided references, the work synthesizes prior theoretical contributions, design primitives, and applied systems into a cohesive framework for understanding how reconfigurable hardware can be used to meet confidentiality, integrity, and availability goals while enabling scalable high-performance computation in multi-tenant and cloud settings. The abstract outlines key objectives, methodological approach, primary results, and implications. First, we concisely state the motivation: massive datasets and computational workloads require hardware acceleration, yet introduce new attack surfaces and privacy concerns in cloud and shared infrastructures (Hong et al., 2018; Huffmire et al., 2008). Second, the methodological approach is a normative synthesis of architectural primitives (isolation, memory policy enforcement, and secure accelerators), cryptographic overlay techniques (garbled circuits and privacy-preserving MAC on FPGA), and system-level strategies for trust management and tenancy (Huffmire et al., 2007; Huang et al., 2019; Hussain et al., 2018). Third, primary findings emphasize that combining spatial and temporal isolation primitives (Moats and Drawbridges), enforced memory policies, and hardware-accelerated cryptographic protocols can yield systems that deliver both performance and measurable privacy benefits in cloud-scale deployments (Huffmire et al., 2007; Huffmire et al., 2008; Hong et al., 2018). Fourth, the article contributes a unified theoretical taxonomy, an extended method for mapping dataflow to secure FPGA fabrics, and a set of concrete design recommendations for architects and cloud operators. The discussion addresses trade-offs, limitations, and a roadmap for integrating zero-trust tenancy with reconfigurable hardware accelerators, while the conclusion distills actionable design axioms. The analysis aims to guide future empirical evaluations and stimulate development of secure FPGA-enabled cloud services that are both performant and privacy-aware.
