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.…”

IEEE 802.1x-based user identity-embedded IPv6 address generation scheme by Peng KUANG, Ying LIU, Lin HE, Gang REN

“…Embedding extensible user identities into IPv6 addresses not only provides the possibility of tracing the user identity and finely controlling the user behavior,but also helps to improve the security,auditability and credibility of the Internet.Current schemes that embed user identity within IPv6 address are hard to deploy in practice due to the complexity of DHCPv6 client development or the complicated management of temporary address.Considering the sequential logic between identity authentication and address allocation,a IEEE 802.1x-based user identity-embedded IPv6 address generation scheme was proposed.By conducting identity authentication using layer-2 mechanisms and then assigning IPv6 addresses,this scheme decoupled the process of identity authentication and address allocation,and avoided the limitation of developing new extended DHCPv6 clients for each operating system and maintaining temporary address leases on DHCPv6 servers,which was more deployable.…”

Internet source address verification method based on synchronization and dynamic filtering in address domain by Dan LI, Lancheng QIN, Jianping WU, Yingying SU, Mingwei XU, Xingang SHI, Yunan GU, Tao LIN

“…At the beginning of the design of the Internet architecture,it assumed that all network members were trusted,and did not fully consider the security threat brought by the untrusted network members.For a long time,routers only forward packets based on the destination IP address of the packet,and do not carry out any verification on the source IP address of the packet.The lack of packet level authenticity on the Internet results in the header being maliciously altered.A real source address verification mechanism with routing synchronization and dynamic filtering were proposed.This mechanism constructs the filter table based on the prefix-topology mapping synchronization,the problem of inconsistent state between the filter table and the route caused by routing asymmetry were solved,false positives and false negatives was avoided,and a low-overhead and low-latency source address verification of the IP address prefix level granularity in the address domain were realized.…”

Optimum response scheme of intrusion detection based on information theory by Youliang TIAN, Yulong WU, Qiuxian LI

“…Intrusion detection system (IDS) often inevitably presents major security risks caused by FPs and FNs.However,at present,an effective solution has not been found.In order to solve this problem,an optimal response model of intrusion detection based on information theory was proposed.Firstly,the intruder and IDS in the process of intrusion detection were abstracted into random variables,and the attack and defense model of intruder and IDS was constructed according to the results of the confrontation.Secondly,the defense channel of IDS was designed according to the attack and defense model,then the correct detection of IDS was transformed into the problem of successful transmission of 1 bit information in defensive channel.Finally,the defensive capability of the system was measured by analyzing the channel capacity of the defensive channel,the maximum mutual information of the defensive channel was the defensive limit capability of the IDS,and the corresponding strategy distribution was the optimal response strategy of the defensive capability of the system.The experimental results show that the scheme can effectively reduce the loss caused by FPs and FNs.…”

Block-based fair payment scheme under delegation computation by Ta LI, Youliang TIAN, Kang XIANG, Hongfeng GAO

“…In the traditional delegation computation,due to the self-interested behavior of both participants,there were some problems such as the denial of the principal and the dishonest calculation by the computing party.In the payment phase,a third party was required to ensure the fairness of the payment,which led to extra costs and risks of disclosure of participants' privacy.Game theory was used to analyze the Nash equilibrium solution between the two parties in the payment process,and a fair payment protocol based on time commitment of bitcoin was proposed.Firstly,the bitcoin time commitment technology was used to ensure the fairness of payment.Secondly,the decentralized feature of block chain was used to replace the third-party service to protect the privacy of all parties and realize the source of responsibility.Finally,the scheme was analyzed from the perspective of security and correctness,which proved that the participants choose behavioral strategies honestly in the payment process.The scheme proposed in this paper not only solved the problem of fair payment in traditional delegation computation,but also protected the privacy of participants.…”

Traceable attribute-based encryption scheme with key-delegation abuse resistance by Xixi YAN, Xu HE, Tao LIU, Qing YE, Jinxia YU, Yongli TANG

“…Aiming at the problem that the traceability of a traceable attribute-based encryption (ABE) scheme was not sufficient to address the key abuse completely,a traceable ABE scheme against key-delegation abuse was proposed.A secret parameter was be shared to all user private key components corresponding to attributes,and the decryption was completed by using all these components together,such that only parts of them could not realize the decryption and the real key-delegation abuse resistance ability was be obtained consequently.A short signature technique was employed to prevent the tracing parameter embedded in a user private key from being forged,so as to achieve the traceability of the user who leaked his user private key.Supporting both key-delegation abuse resistance and user tracing enhances the security of the proposed scheme.And compared with related schemes,the proposed scheme has better advantage in terms of the parameters size and the computation cost.…”
