Interpretable Encrypted Searchable Neural Networks
This work addresses efficiency issues in cloud security for users needing encrypted search with dynamic updates, representing an incremental improvement over existing methods.
The paper tackles the problem of high computation and communication overhead in traditional searchable encryption for dynamic cloud environments by proposing interpretable encrypted searchable neural networks (IESNN), which reduce query complexity to near O(log N) with low overhead.
In cloud security, traditional searchable encryption (SE) requires high computation and communication overhead for dynamic search and update. The clever combination of machine learning (ML) and SE may be a new way to solve this problem. This paper proposes interpretable encrypted searchable neural networks (IESNN) to explore probabilistic query, balanced index tree construction and automatic weight update in an encrypted cloud environment. In IESNN, probabilistic learning is used to obtain search ranking for searchable index, and probabilistic query is performed based on ciphertext index, which reduces the computational complexity of query significantly. Compared to traditional SE, it is proposed that adversarial learning and automatic weight update in response to user's timely query of the latest data set without expensive communication overhead. The proposed IESNN performs better than the previous works, bringing the query complexity closer to $O(\log N)$ and introducing low overhead on computation and communication.
