Supporting dynamic updates in storage clouds with the Akl-Taylor scheme

In order to overcome such limitations, in this work we provide new results on the Akl-Taylor scheme, by carefully analyzing the problem of supporting dynamic updates, as well as key replacement operations. In doing this, we also perform a rigorous analysis of the Akl-Taylor scheme in the dynamic setting characterizing storage clouds, by considering different key assignment strategies and proving that the corresponding schemes are secure with respect to the notion of key recovery.
