In Database Security Using Encrypted Private Key, we propose a secure data handling scheme for dynamic members of an organization. Firstly, we create a secure way for a private key distribution with a secure communication channel, so that the users can securely obtain their private keys from the organization admin. Secondly, our scheme can achieve fine-grained access control, any user in the group can use the source in the database and revoked users cannot access the database again after they are revoked. Thirdly, we can protect the scheme from collusion attack, which means that revoked users cannot get the original data file even if they conspire with the untrusted database. In our approach, by leveraging polynomial function, we can achieve a secure user revocation scheme. Finally, our scheme can achieve fine efficiency, which means previous users need not to update their private keys for the situation either a new user joins in the group or a user is revoked from the group.
