SDN based e-mail repudiation source restraining method by Zhi-geng HAN, Xia FENG, Geng CHEN

“…With the limitation of controllability of the existing Internet architecture,the existing secure e-mail technology such as certified e-mail can only post detection but cannot source restraining on e-mail repudiation.Based on the idea of control and data separation of software-defined networking technology,by means of bypass attaching customized repudiation restrain unit to the traditional e-mail model.An e-mail repudiation source restraining method was proposed without destroying the existing e-mail structure.After presenting e-mail evidence binding protocol,repudiation behavior detection algorithm,certified reputation evaluation model,and repudiation restraining strategy formation algorithm embedded in repudiation restrain unit,the effectiveness were tested of the proposed method in 4 cross scenarios.The experimental results show that,under the premise of compatibility with the current e-mail system,the method can source restrain e-mail repudiation effectively.…”

Multi-authority ABS supporting dendritic access structure by Ruo MO, Jian-feng MA, Xi-meng LIU, Qi LI

“…Attribute-based signature (ABS),which could realize fine-grained access control,was considered to be an important method for anonymous authentication in cloud computing.However,normal ABS only provided simple access control through threshold structure and thus could not cope with the large-scale attribute sets of users in the cloud.Moreover,the attribute sets were supervised by only one attribute authority,which increased the cost of computation and storage.The whole system was in danger of collapsing once the attribute authority was breached.Aiming at tackling the problems above,a novel scheme,was proposed called multi-authority ABS supporting dendritic access structure which supported any AND,OR and threshold gates and affords more flexible access control.Meanwhile,the attribute sets of users were classified by diverse attribute authorities which reduced the overhead and the risk of systems.Besides,the scheme is proved to be selective predicate chosen message attack secure in the random oracle model.…”

HDFS-oriented cryptographic key resource control mechanism by Wei JIN, Fenghua LI, Mingjie YU, Yunchuan GUO, Ziyan ZHOU, Liang FANG

“…The big data environment presents the characteristics of multi-user cross-network cross-access, multi-service collaborative computing, cross-service data flow, and complex management of massive files.The existing access control models and mechanisms are not fully applicable for big data scenarios.In response to the needs of fine-grained access control and multi-service strategy normalization for cryptographic data in the big data environment, starting from the scene elements and attributes of access control, the HDFS-oriented CKCM was proposed by mapping the cyberspace-oriented access control (CoAC) model.Subsequently, a fine-grained access control management model for HDFS was proposed, including management sub-models and management supporting models.The Z-notation was used to formally describe the management functions and management methods in the management model.Finally, the CKCM system was implemented based on XACML to realize fine-grained secure access control for managing file and secret keys in HDFS.…”

Millimeter-wave array enabled UAV-to-UAV communication technology by Zhenyu XIAO, Ke LIU, Lipeng ZHU

“…As the application scope of unmanned aerial vehicle (UAV) expands and the tasks become more complicated, the demands for large bandwidth, high data rate and antijamming capability in UAV-to-UAV (V2V) communication grow rapidly.With abundant spectrum resource, millimeter-wave (mmWave) array communication has been one of the key technologies to support V2V communications.Focusing on the emerging field of mmWave array V2V communication, the difficulties and challenges in point-to-point communication and unmanned aerial vehicle ad-hoc network were analyzed.The problems and approaches for channel modeling, robust beamforming, secure communication in point-to-point communication and neighbor discovery, routing decisions, resource allocation, distributed deployment in unmanned aerial vehicle ad-hoc network were reviewed.Some valuable research directions were summarized to provide inspiration for future relevant research.…”

Comparative study of anonymous network Tor and I2P by Yun YANG, Lingyan LI, Qingzheng WEI

“…Tor is the most deployed anonymous communication system,providing online anonymity and privacy protection,while the invisible Internet project allows applications to send messages to each other anonymously and securely by using garlic routing.The anonymous network Tor and I2P have been highly valued by the academic community and the industry,and are also welcomed by users.The key difference between the design concept between the Tor network and the I2P is that I2P attempts to transfer the existing Internet service to the I2P network,and service implementation is provided within the framework,while Thor allows anonymous access to implement and operate external Internet services separately.The anonymous networks Tor and I2P in terms of terminology,project development,anonymous services,key technologies,threat types,etc.were compared,revealing the inherent and essential differences between the two anonymous networks.…”

Possible paths towards sustainable tourism development in a high-mountain resort by Laurent Arcuset

“…The local approach of "sustainable tourism", indeed, seems for the moment rather to aim - as in many other high mountain ski resorts - towards a more environmental management of the basic urban functions than a real questioning of a tourist model based upon the triptych development of the ski slopes, securizing of the snow resource and touristic real estate programs.…”

Practical group signature scheme with verifier-local revocation by LI Ji-guo, SUN Gang, ZHANG Yi-chen

“…An efficient approach of member revocation in group signature is verifier-local revocation.In this approach,revocation messages are only sent to signature verifiers,while signers have no involvement.There are some problems in group signature with verifier-local revocation;for example,some group signature schemes do not have exculpability and the computation cost of revocation check is dependent on the length of the revocation list,and so on.In order to solve above problems,and aim at the application of group signatures for enabling privacy-preserving attestation,a practical group signature scheme with verifier-local revocation based on the strong Diffie-Hellman assumption and decision linear Diffie-Hellman assumption,which was proven to be secure in the random Oracle model was proposed.The efficiency of the proposed scheme was analyzed.Compared with the existing verifier-local revocation group signatures,the computa-tion cost of revocation check in the scheme is independent of the length of the revocation list.At the same time,the scheme satisfies exculpability and backward unlinkability.…”

Privacy-preserving attribute-based encryption scheme on ideal lattices by Xixi YAN, Yuan LIU, Zichen LI, Yongli TANG, Qing YE

“…Based on the small key size and high encryption efficiency on ideal lattices,a privacy-preserving attribute-based encryption scheme on ideal lattices was proposed,which could support flexible access policies and privacy protection for the users.In the scheme,a semi-hidden policy was introduced to protect the users’ privacy.Thus,the sensitive values of user’s attributes are hidden to prevent from revealing to any third parties.In addition,the extended Shamir secret-sharing schemes was used to construct the access tree structure which can support “and” “or” and “threshold” operations of attributes with a high flexibility.Besides,the scheme was proved to be secure against chosen plaintext attack under the standard mode.Compared to the existing related schemes,the scheme can yield significant performance benefits,especially the size of system public/secret keys,users’ secret key and ciphertext.It is more effective in the large scale distributed environment.…”
