Disclosed is a method for searchable symmetric encryption. The method for performing searchable encryption and searching for encrypted data includes: setting all necessary variables and preparing a secret key necessary for encryption; encrypting a data using the secret key and a given data and generating an index to be used for later search, to store the encrypted data and the index; generating a trapdoor to be used to search the encrypted data by using the secret key and a keyword to be used for the searching; and searching a desired data using the generated trapdoor and the stored index.
