Outline of Final Research Achievements |
By utilizing cloud environments, we can outsource computer system maintenance, but simultaneously we encounter the risk of disclosing confidential data. Thus it is important to realize countermeasures against such a threat. However, employing encryption techniques simply prevents outsourcing of computation on confidential data. In this project, we worked on developing cryptographic techniques by which we can outsource and utilize confidential data simultaneously.
