Investigating the Adoption of Hybrid Encrypted Cloud Data Deduplication With Game Theory

Encrypted data deduplication, along with different preferences in access control, brings the birth of hybrid encrypted cloud deduplication (H-DEDU for short). However, whether H-DEDU can be successfully deployed practice has not been seriously investigated. Obviously, adoption depends on it bring economic benefits to all stakeholders. But existing models storage fail support due complicated interactions among In this article, we establish a formal model by formulating utilities involved stakeholders, i.e., holders, owners, and Cloud Storage Providers (CSPs). Then, construct multi-stage Stackelberg game, which consists Holder Participation Game, Owner Online CSP Pricing capture system We further analyze conditions existence sub-game perfect Nash Equilibrium propose gradient-based algorithm help stakeholders choose near-optimal strategies. Extensive experiments show feasibility proposed achieving game. Additionally, investigate effects parameters related CSP, owners holders adoption. Our study advises best strategies adopt H-DEDU.
