Database management is resource consuming. An appealing solution is to export
database services to the cloud, which raises privacy concerns, too. Among the existing
approaches, cryptoindexis a simple solution (not so secure) that transforms a domain
to a set of random IDs. It is easy to process queries on transformed data. However, the
result may have low precision. In this task, you will implement a simple crypto index method and experiment with single dimensional range query on transformed data.
