摘要

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