Searchable Symmetric Encryption with Forward Search
Privacy
ABSTRACT:
Searchable symmetric encryption (SSE) has been widely applied in the encrypted
database for queries in practice. Although SSE is powerful and feature-rich, it is
always plagued by information leaks. Some recent attacks point out that forward
privacy which disallows leakage from update operations, now becomes a basic
requirement for any newly designed SSE schemes. However, the subsequent
search operations can still leak a significant amount of information. To further
strengthen security, we extend the definition of forward privacy and propose the
notion of “forward search privacy”. Intuitively, it requires search operations over
newly added documents do not leak any information about past queries. The
enhanced security notion poses new challenges to the design of SSE. We address
the challenges by developing the hidden pointer technique (HPT) and propose a
new SSE scheme called Khons, which satisfies our security notion (with the
original forward privacy notion) and is also efficient. We implemented Khons and
our experiment results on large dataset (wikipedia) show that it is more efficient
than existing SSEschemes with forward privacy.

Searchable Symmetric Encryption with Forward Search Privacy

  • 1. Searchable Symmetric Encryption with Forward Search Privacy ABSTRACT: Searchable symmetric encryption (SSE) has been widely applied in the encrypted database for queries in practice. Although SSE is powerful and feature-rich, it is always plagued by information leaks. Some recent attacks point out that forward privacy which disallows leakage from update operations, now becomes a basic requirement for any newly designed SSE schemes. However, the subsequent search operations can still leak a significant amount of information. To further strengthen security, we extend the definition of forward privacy and propose the notion of “forward search privacy”. Intuitively, it requires search operations over newly added documents do not leak any information about past queries. The enhanced security notion poses new challenges to the design of SSE. We address the challenges by developing the hidden pointer technique (HPT) and propose a new SSE scheme called Khons, which satisfies our security notion (with the original forward privacy notion) and is also efficient. We implemented Khons and our experiment results on large dataset (wikipedia) show that it is more efficient than existing SSEschemes with forward privacy.
