Abstract

Cloud computing is beneficial in terms of low cost and accessibility of data. In the preceding research, the issue of data replication is solved on distributed systems. To ensure the security, the existing system used a Multilevel Differential Evolution Threshold (MDET) based secret sharing scheme of security in cloud computing. However the existing system is not useful for multiple cloud users and the problem of resource wastage is not solved optimally. To avoid the above mentioned issues, in the proposed system, Multilevel Bat Threshold (MBT) is proposed to protect the secret keys. For improving the privacy as well as security, MBT algorithm is used to encrypt the file using the secret key prior to share out the keys between resource providers whom assume to be honest. In the proposed research, it split secret keys into multiple shares and stores them in diverse locations using MBT secret sharing algorithm. To handle the data corruption issue, Multi-Stage Stochastic Integer Programming (MSSIP) is adopts the intuitive idea of Quality of Service (QoS) to perform data replication. MBT secret sharing scheme create replicas of secret shares and distribute them among multiple resource providers to ensure availability. Thus the result proves that the proposed MBT based secret sharing scheme is potential to handle threats as well as to identify relate vulnerabilities with possible solutions when compared to existing state of art methods. It provides higher security and privacy for multi cloud users using MBT algorithm significantly.
