Abstract:
A server provides the user's desired data without the server knowing the contents or keywords of data by using a method of searching the desired data without decrypting the encrypted data, such that the privacy for the important data of the user can be secured. Also, the present invention shortens the operation time when searching the encrypted data, such that it can prevent the degradation in efficiency due to excess operation involved in the previous existing methods based on the pairing operation.
