The development of location-based services (LBS) caused serious privacy concerns.Semantic-based pri-vacy-preserving approaches is an important part of privacy protection in LBS.The recent work on location privacy protection based on semantics were summarized,including key factors in design of privacy protection,the feasibility of semantic protection,related concepts.Then semantic-based location privacy-preserving mechanisms,measure-ment methods of semantic similarity,evaluation index of privacy for semantic location privacy were discussed.Fi-nally,some future research directions of semantic-based location privacy protection were prospected.

Quantum secret sharing (QSS) is one important branch of quantum cryptography.Based on the studies of multi-shared quantum bits,a new dynamic quantum bit sharing protocol was proposed.The participation of the shared members is hierarchical in this protocol.The quantum information leader,in the absence of the establishment of a new quantum channel,can remove some of the participants in the secret reconstruction system.After the layoffs,the leader can also update the quantum information using quantum operations,and the remaining effective partici-pants can recover the new quantum information without performing additional operations.In addition,the correct-ness,security and the hierarchy of the participants of the protocol were discussed.

With the rapid development and wide application of the digital media technology,the information security problem is becoming more and more highly attention.Because of the various kinds of medias,previous research works have focused on a specific digital media from,such as text,image,audio and video.As a fact that all the objects were expressed in digital forms under the environment of computer and network,a unified form for all kinds of digital media under the complex number base system was proposed.The algorithm of the digital media signal and the complex number intercom version were given,so the relationship among the digital media could be converted to the corresponding geometric relationship on the complex plane.In the experiments,the proposed method was applied to the application of the digital media information hiding.

Most of the interfaces for mobile application and server interaction use the Web API for communication,but the Web API introduced by these mobile applications may introduce new security issues.To facilitate the study of the security of Web API,a system for automatically discovering the server-side Web API interface in APK files based on the conventional Android program testing framework was designed and implemented.This system can help to develop the research on private server-side Web API interface security.

Aiming at the security problem that the existing in electronic surveys,such as information fraud,privacy security etc.An anonymous electronic survey scheme based on non-interactive zero knowledge proofs (NIZK) was constructed,which had the characteristics of self-organization,non-interactive,anti-replay,and high efficiency.The system uses the NIZK protocol and the Boneh-Boyen signature scheme to verify the user's identity in non-interactive manner,which guarantees the authenticity of the scheme.The system also uses the Pedersen commitment scheme and the pseudo random function to hide the user's identity and the related information,which guarantees the ano-nymity.Security analysis show that the system has security features such as malicious users attack resistance and anonymity.Finally,the function of the system was also verified and the result show that the system can accomplish all the functions correctly and guarantee the anonymity and authenticity of the system effectively.

Based on the reaserch status of networking troubleshooting in software defined network,a new net-working troubleshooting method was proposed.A TCP packet marked in head field was sent and detailed forward information in every hop would be written in its data filed once the test packet was matched.Taking advantages of the programmable feature of the controller and OpenFlow extensible match,special flow table was designed for matching test-used packet.The analysis module extracted and split the forward information,and thus printed the suspicious network problem which can be used to track and located the problematic network node.The experiment results indicate that the proposed method is fairy efficient.
