Improved Authentication Scheme for Dynamic Groups in the Cloud
نویسنده
چکیده
Nowadays, most of the organizations managing data to the cloud such that an active member of the group can able to share data with other members of the group. Because of its insecure nature, we propose Initiator which acts as the middleware between the group manager and the data owners for providing versatile authentication mechanism. The initiator sends a key generation request to Group manager [1] with a list of group members. Key confidentiality is provided by INITIATOR due to the security feature of a data sharing scheme. The vulnerabilities that may be exploited by attackers are reduced and the security analyses prove that the middleware is secure. Keywords— IAS, Key Generation Centre, Group Manager, Intruders, Security.

While cloud computing is growing at a remarkable speed, privacy issues are far from being solved. One way to diminish privacy concerns is to store data on the cloud in encrypted form. However, encryption often hinders useful computation cloud services. A theoretical approach is to employ the so-called fully homomorphic encryption, yet the overhead is so high that it is not considered a viable s...
