Scalable and secure data sharing for dynamic groups in cloud

摘要: Cloud computing plays an important role in data sharing or transfer of information from one place to another. The services provided by the cloud are greatly enjoyed user. storage user's provides high standard qualities and more enjoyable users. users payment depends on your used cloud. centre shares many performances user efficient way such as utilizes opportunity at right time, waiting perfect responsiveness user, quickly availability efficiency capacity. Sharing group resource among is a major problem, so economical solution. Due frequent change membership, multi-owner manner untrusted still challenging issue. In this paper, we propose secure scheme, for dynamic By providing signature broadcast encryption techniques, any can securely share with others. Meanwhile, overhead computation cost scheme independent number revoked addition, analyze security rigorous proofs. One-Time Password easiest most popular forms authentication that be securing access accounts. Passwords often referred stronger authentication, allowing them install across multiple machines. We provide levels manner. Our model gives full work when compared previous system shown through our simulation implementation analysis.
