Zero-Knowledge Proofs for Enhancing Data Privacy in Multi-Tenant Cloud Environments

Abstract

Data privacy concerns in multi-tenant cloud environments have become increasingly critical as more organizations adopt cloud services. Traditional encryption methods provide data confidentiality but lack assurances against unauthorized access by cloud providers or other tenants sharing the infrastructure. Zero-knowledge proofs (ZKPs) offer a promising solution by allowing one party (the prover) to prove knowledge of certain information to another party (the verifier) without revealing the information itself. This paper explores the application of ZKPs in enhancing data privacy within multi-tenant cloud environments, discussing their benefits, challenges, and potential implementation strategies.
