Cloud computing has emerging as a promising pattern for data outsourcing and high-quality data services. However, concerns of sensitive information on cloud potentially causes privacy problems. Data encryption protects data security to some extent, but at the cost of compromised efficiency. Searchable symmetric encryption (SSE) allows retrieval of encrypted data over cloud. In this paper, we focus...
In this paper, we focus on data privacy of searchable symmetric encryption (SSE) in cloud computing. For the first time, we formulate the privacy issue from the aspect of similarity relevance and scheme robustness and then prove server-side ranking based on order-preserving encryption (OPE) inevitably leaks data privacy. In order to solve this problem, we propose a two round searchable encryption...
Spyware is a kind of malicious code that is installed on victims' machines without their content. They spy on the users' behavior and compromise their privacy, while transmitting sensitive information to some remote servers. Current anti-spyware tools are similar to anti-virus products in that they identify known spyware by comparing the binary image to a database of signatures. Unfortunately, these...
