PAT: A precise reward scheme achieving anonymity and traceability for crowdcomputing in public clouds

摘要: Abstract While providing anonymity at terminal devices (e.g. Android and iOS devices) is beneficial for users consuming services resources without the risk of being traced), relevant stakeholders providers governments) may require conditional billing purpose or to locate dishonest compromised client devices. In a cloud computing deployment where large number computation tasks are submitted public cloud, server encounter peak hence, responses be delayed. Thus, in this paper, we design first precise reward scheme achieving both traceability crowdcomputing clouds. We then prove security proposed random oracle model, demonstrate practicality using simulations.
