Encryption and decryption can be used to the security of data orudimportant documents. Many methods have been developed to perform encryptionudand decryption. In this article, the research is conducted to develop a corpus ofudsemantic similarity in Indonesian, and query rewriting technique that is used as oneudmethod of encryption and decryption. Corpus of semantic similarity is used to find audnew query that will form a new document encryption, and the technique that isuddeveloped in this study is to secure documents in Indonesian. Encrypted documentudis using query rewriting techniques and corpus of semantic similarity, it will be auddocument with a good sentence structure, so it looks like the original document andudis not expected to attract the attention of hackers. The categorization of documentsudwas also performed on the stage of the encryption.
