DDoS defense with IP traceback and path identification by JIN Guang, ZHANG Fei, QIAN Jiang-bo, ZHANG Hong-hao

“…A novel idea to combine both IP traceback and path identification（Pi） was proposed,and malicious packets could be identified and filtered at located upstream nodes.Then a practical packet marking and filtering scheme was proposed.The nodes along the path out of the destination domain deployed Pi.Meanwhile the border router of the destination domain deployed the traceback marking scheme.The victim could retrieve related information from arrived malicious packets.Then Pi-based filtering could be implemented at the border ingresses.A practical marking,storing and filtering scheme was provided in detail.The results of large-scale simulations with authoritative Internet topologies show the scheme is effective to alleviate attack impacts on the victim and upstream links in the destination domain.…”

Optimization design of structure invulnerability for air defense multiple sensor network by Cheng-yu SUN, Mao-xing SHEN, Hao SHENG, Jin-ke XIAO

“…To improve the invulnerability of air defense multiple sensor network,its topological structure optimization model was established with the constraint of network node’s degree and network connectivity,combined with the total sum of network’s natural connectivity for attack strategy as object function.Then,solving steps of the model were designed based on improve artificial immune algorithm to solve the model.In order to improve the searching efficiency of the algorithm,new steps of immune review and antibody correction were designed to increase the number of effective antibodies in population.Simulation and results prove rationality of the model and feasibility of the modified artificial immune algorithm,optimization based on the index of total natural connectivity for attack strategy can improve the invulnerability of air defense multiple sensor network.…”

Coda: The Open by Michael Palmer

“…Exploring little known areas in American poetry, namely the 1973 anthology of Open Poetry put out by Ronald Gross and George Quasha, but also Charles Olson’s projective verse project, the full scope of Duncan’s Opening of the Field comes into view as an attempt at a new condition of poetry, as a kind of topological reality, where compositional decisions proceed seemingly from ad hoc pressures as if it too were a form of listening to the text. …”

On r-Generalized Fuzzy ℓ-Closed Sets: Properties and Applications by I. M. Taha

“…In the present study, we introduce and characterize the class of r-generalized fuzzy ℓ-closed sets in a fuzzy ideal topological space X,τ,ℓ in Šostak sense. Also, we show that r-generalized fuzzy closed set by Kim and Park (2002) ⟹r-generalized fuzzy ℓ-closed set, but the converse need not be true. …”

UAV ad hoc network link prediction based on deep graph embedding by Jian SHU, Qining WANG, Linlan LIU

“…Aiming at the characteristics of the UAV ad hoc network (UAANET), such as topological temporal-varying, node mobility and intermittent connection, a temporal graph embedding model was proposed to present the preprocessed UAANET.To improve the sampling efficiency, the sampling interval was calculated based on linear probability.The network structure features were mapped to the relationship between nodes, and the contextual semantic features of nodes were extracted by adversarial training.With the help of long and short-term memory network, the temporal characteristics of the UAANET were extracted to predict the connection at the next moment.AUC, MAP, and Error Rate were employed as evaluation indexes.The simulation experiments based on NS-3 show that compared with Node2vec, DDNE and E-LSTM-D, the proposed method has a better accuracy.…”

Optimal path identification to defend against DDoS attacks by JIN Guang1, YANG Jian-gang1, LI Yuan2, ZHANG Hui-zhan2

“…A novel packet marking scheme,optimal path identification（OPi）,was proposed to defend against DDoS at-tacks.Instead of using fixed 1 or 2 bit in previous schemes,in OPi a router deduces the traveling distance of an arrived packet by its TTL value and inserts a variable-length marking of 1~16 bit into the packet.The marking field is filled completely even the path is very short and the distinguishability is improved.OPi outperforms previous schemes,espe-cially when attacker paths adjoin user paths seriously.To obtain better performance,an OPi+TTL filtering strategy was proposed to frustrate attackers’ tries with spoofed initial TTL values.Theoretical analyses and simulations with actual Internet topologies show OPi performs excellently.…”
