Hiding solutions in 3-SAT formulas can be used in privacy protection and data security. Although the typical q-hidden algorithm could cancel the attraction to the unique predefined solution, and generate deceptive 3-SAT formulas with unique predefined solution, few works have mentioned that with multiple predefined solutions. Therefore, the objective of this paper is to propose algorithms which could...
The negative database (NDB) is a new technique for privacy preserving and information hiding. It hides information by storing the complementary set instead of the original data. In order to protect the hidden information, NDBs should be hard-to-reverse. In this paper, we propose the Khidden algorithm for generating hard-to-reverse NDBs (called Khidden-NDBs). The K-hidden algorithm could be controlled...
Cognitive radio (CR) is a promising technology which improves the spectrum utilization. Cooperative spectrum sensing (CSS) has been adopted to exploit spatial diversity in cognitive radio networks (CRNs). Since CSS is subject to attacks from malicious users, several secure schemes have been proposed recently. But, they only utilize current information to estimate the reliability of secondary users...
In this paper, the value-relevance of the Chinese stock market investment and accounting information is studied from three aspects of the stock price, stock value and stock risk. It is found that, in terms of the value-relevance of the Chinese stock market and accounting information, the accounting information released by listed companies did pass information to the stock market in China, making the...
A web service security analysis model based on program slicing is proposed, which can be used to find existence of critical information disclosure vulnerabilities and proliferation of such vulnerabilities in a web service net, and eventually improve protection of critical information. Web service protocol is analyzed to obtain external service interfaces; source code is sliced to obtain interface...
