Achieving Simple, Secure and Efficient Hierarchical Access Control in Cloud Computing
Abstract—Achieving Simple, Secure and Efficient Hierarchical Access Control in Cloud Computing. Access control is an indispensable security component of cloud computing, and hierarchical access control is of < Final Year Projects 2016 > interest since in practice one is entitled to different access privileges. A hierarchical key assignment scheme based on linear-geometry as the solution of flexible and fine-grained hierarchical access control in cloud computing. In our scheme, the encryption key of each class in the hierarchy is associated with a private vector and a public vector, and the inner product of the private vector of an ancestor class and the public vector of its descendant class can be used to derive the encryption key of that descendant class.
