    The typical cloud storage architecture was presented as research objects and the privacy preserving mechanism of attribute-based encryption cloud storage including following aspects-data owner,cloud servers,au-thorized agency,data user and revocation of user was researched.By analyzing and comparing,it was discovered that the privacy preserving problems of cloud storage could be divided into privacy issues of users' identity,sensitive attribute information disclosure and leakage of privacy content in the system.Aiming at the above problems,the current privacy preserving mechanism of attribute-based encryption cloud storage was studied and shortages of the present schemes,possible solutions and the study trend in the future were discussed.

    Due to the lack of metric standards and the metric imprecise problems of cloud service information secu-rity,the research status of the relevant standards at home and abroad were introduced.As for the demand for infor-mation security measurement requirements of the trusted cloud,the advantages and disadvantages of metric models based on the trusted root were analyzed.At last,the future research direction which was to study a scalable com-bined,real-time,privacy protected,easy to transplant and less cost metrics model was pointed out.

    The traditional file sharing way is single,lack of security,and the shared file's permission autonomous control is too high.To solve these problems,a file encrypted storage and hierarchical access control scheme was proposed.Through increasing classification management unit in the system,classification of users and documents,users of file access control were achieved,the scope of file access control was realized.Security of file storage and transmission was realized through encryption,the key storage was simplified using hierarchical key.Server file en-cryption and decryption operations were achieved through a special password card,which reduced the server work-load and accelerated the file encryption and decryption processing.The scheme was verified on PC and Zynq plat-form,and the predetermined function was realized.

    In space-earth integration network,high-speed movement of space nodes brings in the problem of fre-quent satellite access router (SAR) handover.A group-based secure handover scheme for multiple mobility nodes (MN) utilizing satellite trajectory prediction was proposed.By using the movement features of the corresponding entities,an efficient aggregation mechanism for the interaction message occurred during the multi-MN handover was put forward.By using predictable satellite trajectory,authentication and session key agreement between new SAR and MN was accomplished beforehand with the secure context.Compared with existing schemes,the proposed scheme can provide necessary security features,lower the handover delay,and reduce the computation and commu-nication overhead of mutual authentication and key agreement.The proposed scheme well suits the space-earth inte-gration network,where the satellite node is energy constraint.

    Differential demodulation is an important method of solving the information transmission which is used in the high dynamic condition of the wireless communication.The coding rate for differential modulation and detec-tions neither be too high,nor be too low.To find the optimal coding rate,the Shannon limit of error free transmis-sions with different rates for differential BPSK and differential QPSK were derived.Thereafter,the optimal coding rate was obtained from the view point of information theory.Convolutional codes and Turbo codes with different rates were employed,and simulations were conducted for the verification of the result.

    The particular characters of Trojan are not fully taken into consideration by existed network attack effect evaluation systems which mainly focus on DDoS and Warm.A few Trojan harm measurement systems is somewhat short for objectivity and completeness as the result of that its indicator values is confined to manually marked and qualitative values.Under the circumstances,the analysis of Trojan's features were started from,and a hierarchical index system which accepted both quantitative and qualitative values,and both manually marked and system col-lected values was built.Then,a FAHP based evaluation model was proposed to evaluate the Trojan attack effect.Meanwhile,a many-to-one method to ensemble multiple weight vectors was proposed.Finally,the rationality of proposed evaluation system was verified by comparison with others.

    In order to analyze the potential vulnerabilities in the firmware systematically and effectively,a formal verification method based on TLA,in a collaborated form of software and hardware was proposed.With this method,the interaction mechanism of software and hardware in the computer boot process was modeled and analyzed.By adjusting the attack model,a secure vulnerability in the update process of the firmware was found,and its existence by an experiment,which proved the reliability of formal verification was demonstrated.

    In order to extract feature information of side channel signal from the strong noise,the approach of signal feature extraction was proposed on account of empirical mode decomposition (EMD) and difference spectrum of singular value.Firstly,using EMD to decompose the original side channel signal,the correlation coefficient between all the intrinsic mode functions (IMF) and the original signal were calculated to find the component of biggest simi-lar characteristic.Then,to make a singular value decomposition of IMF component and corresponding difference spectrum of singular values was obtained.Finally,according to the difference spectrum,the filtered and recon-structed signal of IMF component was obtained,and the feature information of component was further extracted.The actual examples show that the method can extract characteristic information of side channel signal validly and improve the SNR and success rate of attack of signal successfully.
