英文摘要: Recently, researches on key management scheme for user access control in outsourced databases have been actively done. Because outsourced databases require dealing with a lot of users and data resources, an efficient key management scheme for reducing the number of authentication keys is required. However, the existing schemes have a critical problem that the cost of key management is rapidly increasing as the number of keys becomes larger. To solve the problem, we propose an efficient key management scheme for user access control in outsourced databases. For this, we propose an Resource Set Tree(RST)-based key generation algorithm to reduce key generation cost by merging duplicated data resources. In addition, we propose a hierarchical Chinese Remainder Theorem(CRT)-based key assignment...
