Automated Security Providence for Dynamic Group in Cloud
Data sharing among group resource in the cloud server is a major problem, so cloud computing provides an efficient and economical solution. Due to the change of membership frequently, data sharing in a multi-owner manner to an untrusted cloud is a challenging issue. This proposal provides a secure data sharing scheme for dynamic group in the cloud, by providingAES encryption while uploading the data, any cloud user can securely share data with others. Meanwhile, the computation cost of encryption and storage overhead scheme are independent with the number of revoked users. In addition, this proposal analyze the security of this scheme with rigorous proofs. One-Time Password is the most popular and easiest forms of authentication that can be used for securing access to accounts. OTP are often referred to as a secure and stronger forms of authentication, and it installed across multiple machines. It provides a multiple levels of security to share data among multi-owner manner. First the user selects the text based password. Then the One-Time Password is automatically generated and sent to the corresponding e-mail account.
