ENSURING SECURITY PROOF IN CLOUD NETWORK
Journal Title: Indian Journal of Computer Science and Engineering - Year 2015, Vol 6, Issue 4
Abstract
Cloud Computing is developed and used by all enterprise in world to outsource their data. To maintain confidentiality of shared data against entrusted party encryption of data is important. Many scheme is introduced to achieve security of outsource data in cloud .But they fails to achieve data integrity in cloud. Sometimes entrusted cloud service provider modifies or deletes the data without getting permission from owner in cloud. In this paper we investigate the basic problem of data integrity in cloud. Homomorphic Hierarchical Attribute Based Encryption with integrity proof is proposed in this paper to avoid security risk in cloud. Performance of Homomorphic Hierarchical Attribute Based Encryption is compared with key-aggregate cryptosystem (KAC) and Hierarchical Attribute based encryption(HABE) scheme in cloudsim. Based on data integrity, confidentiality and Validity of data best encryption algorithm is chosen in cloud
