Outsourcing databases into cloud increases the need of data security. Executing queries over encrypted data preserves a certain degree of confidentiality. In this paper, we propose an efficient algorithm to run computations on data encrypted for different principals. The proposed algorithm allows users to run queries over encrypted columns directly without decrypting all records.
