The growing complexity of modern Cyber–Physical Systems (CPS) and the frequent communication between their components make them vulnerable to malicious attacks. As a result, secure state estimation is critical requirement for control these systems. Many existing methods suffer from combinatorial which grows with number states sensors in system. This can be mitigated using optimization-based tha...

Encrypting information has been regarded as one of the most substantial approaches to protect users’ sensitive information in radically changing internet technology era. In prior research, researchers have considered similarity search over encrypted documents infeasible, because the single-bit difference of a plaintext would result in an enormous bits difference in the corresponding ciphertext....

This paper presents the design, implementation and evaluation of Mingle, a secure distributed search system. Each participating host runs a Mingle server, which maintains an inverted index of the local file system. Users initiate peerto-peer keyword searches by typing keywords to lightweight Mingle clients. Central to Mingle are its access control mechanisms and its insistence on user convenien...

In this paper we address the problem of outsourcing sensitive strings while still providing the functionality of substring searches. While security is one important aspect that requires careful system design, the practical application of the solution depends on feasible processing time and integration efforts into existing systems. That is, searchable symmetric encryption (SSE) allows queries o...

With the rise of cloud computing, it is increasingly attractive for end-users (organizations and individuals) to outsource the management of their data to a small number of largescale service providers. In this paper, we consider a user who wants to outsource storage and search for a corpus of web documents (e.g., an intranet). At the same time, the corpus may contain confidential documents tha...
