A Survey on Leakage-Resilient KASE for Group Data Sharing with Auxiliary Input via Cloud Storage

Abstract

Abstract:As cloud computing becomes popular, more and more sensitive information are being centralized into the cloud nowadays. For the protection of data privacy, sensitive data usually have to be encrypted before outsourcing, which makes effective data utilization a very challenging task because all the data which we outsource are in encrypted format. In this paper, we have discussed a few approaches for sharing data on cloud with minimal usage of key. We also discuss few data searching technique over encrypted data. While enjoying the advantage and convenience of cloud storage for data sharing, users are becoming more worried about careless leak of data in the cloud. To address this problem we studied various leakage models.

“…Bhagat and Buchade [24] designed the framework for group data sharing using key aggregate searchable encryption (KASE) for auxiliary input through cloud storage. In a group, data sharing using the KASE method helps to create a single key for multiple files and share the key with the client.…”
