Attribute-based revocable collaborative access control scheme by Changgen PENG, Zongfeng PENG, Hongfa DING, Youliang TIAN, Rongfei LIU

“…To solve the dynamic update of access rights in attribute-based collaborative access control, a novel scheme was proposed with the revocation of attribute, user and collaborative policy.A formal definition and a security model were presented, the group-based attribute group were changed to reflect the update of rights, and further, an efficient re-encryption algorithm was used to realize the immediate revocation of attributes and users.The translation value was used to achieve the revocation of collaborative policy by update corresponding ciphertext.The security analysis shows the scheme can guarantee data confidentiality, forward/backward security, and resist collusion attack under chosen plaintext attack.Compared with the related works, the proposal achieved more complete and efficient revocation scheme.…”

Improved particle filtering based algorithm for time delay and symbols joint estimation of PSK signals by Nan XIA, Tian-shuang QIU

“…An adaptive particle filtering algorithm based on resampling was proposed for time delay estimation of PSK signals,which could eliminate the influence of inaccurate posterior possibility distribution caused by the small noise variance and the influence of the increase of estimation error caused by the large noise variance.Taking into account the small time delay estimation being invalid in the existing algorithms,a symbol forward and backward detection technique was applied to achieve random time delay accurate estimation in a symbol period.Otherwise,the carrier frequency offset of the received signal was estimated and compensated.Simulation results verify the novel algorithm can achieve more accurate time delay estimation and lower symbol error rate than the existing algorithm.…”

RSPEED：the reliability and real-time routing based on uncertain delay in wireless sensor network by Quan CHEN, Hong GAO

“…The forwarding reliability was proposed by considering the unreliability and the delay of a link,and with which,a novel real-time routing protocol(RSPEED) was designed.The forwarding reliability denoted the probability to deliver the data successfully to the neighbor node under a given deadline,and it was used to achieve probabilistic QoS guarantee in timeliness and reliability.The protocol can also make trade-off between the transmission delay and the reliability of transmission to improve the probability of successful transmission when the environment and link quality is very poor.The experimental results show that the proposed approach can significantly improve the reliability of transmission and reduces the number of the missed deadline,and even when the channel is very poor,it can achieve 20% higher performance than SPEED.…”

Study on the application of IGSO into mobile satellite communication by ZHANG Geng-xin1, LI Su-dan2, GAN Zhong-min1

“…The related coverage performance,Doppler shift and service-supporting capability of the IGSO constellation was studied for the given area.The results show that,the constellation,which consists of two or three IGSO satellites,can achieve good coverage characteristics（the percent of time of one and more satellites coverage and average elevation an-gle）to the Chinese and nearby area with small Doppler shift.The link budget shows that,adopting IGSO can effectively solve the low elevation angle problem faced by GEO satellite,and similar performance,which can only be implemented by a very big GEO satellite,can be achieved by two or three relatively small IGSO satellites.So the solution of adopting IGSO to provide mobile satellite communication system is technically feasible.…”

Secure authentication enhancement scheme for seamless handover and roaming in space information network by Kaiping XUE, Huancheng ZHOU, Wei MENG, Shaohua LI

“…Space information network composed of a variety of heterogeneous networks is widely concerned.However,the space information network is facing more security threats and more likely to roam due to its complex topology and large user scale.Considering the characteristics of space information network,a secure authentication enhancement scheme for seamless handover and roaming in space information network was presented.The fast mutual authentication and reasonable accounting between the user and the visiting domain based on the combination of Token and Hash chain was achieved.In addition,two seamless handover mechanisms were proposed to ensure the continuity of user communication.Finally,security analysis indicates that the scheme can not only provide essential security properties,but also achieve reasonable accounting.…”
