Priority-based message forwarding and query processing in opportunistic wireless sensor network by Yong-xuan LAI, Zi-yu LIN

“…A priority-based algorithm called PBQ was proposed for the query forwarding and processing in opportunistic wireless sensor network.Through the user-defined query priorities,the proposed algorithm properly selects the relay nodes and controlls the forwarding and the amount of messages.Meanwhile,the query priorities were adjusted dynamically so that the query results could be forwarded back to the source node of the query quickly and the residual query request messages could be cleaned up from the network,saving lots of unnecessary transmissions and improving the overall utility of query processing.Simulating results show that PBQ could effectively improve the success rate of queries,and reduce the cost and delay of query processing in opportunistic wireless sensor network.…”

Cryptanalysis of a hybrid-structured onion routing scheme by Long-hai LI, Shao-feng FU, Rui-dan SU, Xiang-quan CHE

“…SHI Jin-qiao et al's hybrid-structured onion routing scheme was analysed and some security flaws were found in their design.The first flaw was derived from the malleability of its cryptographic message format which could be exploited by attackers to redirect an onion message or embed tags into it for tracing its routing path.The second flaw was the vulnerability of relay servers to chosen ciphertext attack.Three different attacks were presented that each broke the sender-receiver unlinkability entirely at a relatively low co To evade these attacks,a modified scheme was also proposed which could capture malicious nodes by using upstream investigation.…”

Delay and energy minimization for MEC-based secure communication by Pinyi REN, Qian XU

“…Considering a physical-layer-security-aided confidential document transmission problem,a secure transmission strategy was proposed where the base station equipped with a mobile edge computing (MEC) server served as a relay to help compress,forward,and decompress.First,the Poisson point process was used to calculate the secure transmission probability for the scenario with multiple potential eavesdroppers.Then,a delay and energy minimization problem was formulated under a constraint on the two-hop secure transmission probability.The optimal compression and decompression scheme was obtained using the one-dimensional search combined with linear programming.Simulation results show that the document compression is necessary for the link with small achievable secrecy rate under a given secure transmission probability; otherwise,the document should be directly transmitted without compression.…”

Research on secret key generation based on wireless channel characteristics in body area network by Jingjing HUANG

“…Wireless body area network (WBAN) is a human-centered wireless network.With limitations of power and computation capabilities of WBAN, the significant challenge of ensuring security is how to generate a shared key between two entities based on a lightweight symmetric cryptography.To investigate this issue, a secret key generation scheme in ultra-wideband (UWB) WBAN was designed.In this scheme, the difference of multipath relative delay and its average value were chosen as common random source to reduce key mismatch probability.Furthermore, with the aid of relay, secret key generation rate could be increased.Simulation and test results demonstrate that the proposed scheme can achieve a good tradeoff between key match probability and key generation rate.Furthermore, security analysis of the scheme was also provided to validate its feasibility.…”

Research on cognitive user pairing and cooperative sensing by Zhi-hua BAO, Shi-bing ZHANG, Xiao-ge ZHANG, Gong-an QIU

“…Aim at the shortages of the cooperative algorithm in sensing and time slot spent,an optimal cognitive users pairing and cooperative sensing algorithm was proposed.To achieve the best sensing performance,the pairing criterion was adopted where the one with the best receive SNR was used for the sense user and the one with the second-best receive SNR was used for the relay.According to optimizing cooperation threshold,non-cooperative or cooperative mode was selected,which made time slot spent much lower but sensing ability slight decreasing.Meanwhile,a lower bound of the detection probability and the time slot spent were derived in Rayleigh flat fading channels.Numerical results show the proposed algorithm has higher detection probability and lower time slot spent than the existing one.…”
