Summary
This paper presents Mimi, a new system for searching encrypted data (searchable encryption, where users can find information in coded databases without revealing what they're looking for) that uses two-factor verification to confirm results are correct. Mimi addresses problems in existing systems by using a special tree structure to speed up result verification, supporting fast searches even with large datasets, and protecting encryption keys from being stolen. The system also allows multiple users to search the same encrypted data and handles changes to user permissions and data over time.
