Research on security of mobile payment for commercial bank by Xi CHEN, You-liang TIAN, Zhuo MA, Jian-feng MA

“…There is no doubt that mobile payment is the spotlight in Internet finance now.Although users can enjoy quick and convenient services,they have to face with more severe security problems at the same time:the attack incidents,such as cellphone Trojan and privacy leaks emerge endlessly.Lots of viruses which are designed for attacking financial payments can steal users’ personal information including account,password and verification code in the proceedings of remote payment and near field communication.Security issues have already seriously impeded the further development of the mobile payment market.To solve the above problems,discusses the security issues in mobile terminals,payments,network and interactive logic of banking business from financial institutions’ perspective was discussed systematically.In addition,current status of relevant security key technologies are summarized from academic research community and industry fields.Finally,based on related research achievements,the design of system architecture and suggestions for mobile payment security are proposed,which can guide the future development of commercial bank.…”

Shipwreck Architecture by Simon Weir, Sara Rich

“…This trajectory of ideas is then projected into a creative project: a speculative history of shipwreck architecture where the cutting edge of biological research is projected into a technological future when the distant aims of today’s technology are ancient history: when the first generations of grown buildings are preserved as ruins, when giant decommissioned carbon-capture factories drift like ghost ships across lakes of their inky waste, when people remember when shipwrecks caused by the hazards of rising sea levels were later exposed by sinking sea levels and converted into hotels and theatres, and finally, when these theatrical memories provoke such nostalgia that shipwreck architecture would be replicated and fabricated. …”

Infrastructured Timescapes of the Anthropocene and Climate Change by Claudio Coletta

“…Second, these timescapes are infrastructured, with infrastructure serving both as a key site for producing, organizing and extracting time and as an analytical category to look at temporal work. Finally, because the Anthropocene and Climate Change are temporally infrastructured, efforts at adaptation and mitigation are subject to time leaks, glitches, delays, accelerations, invisibility and performativity that affect time horizons. …”

Data Gathering in Opportunistic Wireless Sensor Networks by Yongxuan Lai, Ziyu Lin

“…The algorithm first collects the network metadata such as history of node encounters and contact durations; then it creates a node contact graph, based on which predictive optimal data gathering locations are dynamically calculated and updated. Finally, the sink is controlled to move to these locations to collect sensing data, avoiding lots of unnecessary data exchanges and message transmissions. …”

Federated edge learning with reconfigurable intelligent surface and its application in Internet of vehicles by Ping WANG, Zhiwei YANG, Heju LI

“…Aiming at the problem that it is difficult to achieve an optimal trade-off between wireless communication and model accuracy in FEEL training caused by the heterogeneity of wireless links and data distribution, a reconfigurable intelligent surface (RIS) enabled federated edge learning system was proposed, which exploited the channel reconfigurability of RIS to adaptively manipulate the signal propagation environment, and utilized the over-the-air computation (Aircomp) to achieve fast model aggregation.Specifically, the convergence behavior of the FEEL algorithm under the influence of wireless channels and data heterogeneity was rigorously derived, and accordingly, an unified wireless resources optimization problem was constructed with the goal of minimizing the learning loss by jointly designing the transceiver design and the RIS phase shift.Simulation results demonstrate that the proposed scheme achieves substantial performance improvement compared against several baselines, and prove that RIS can play an important role in improving the accuracy of Aircomp enabled FEEL systems under data heterogeneity.Finally, the probability of applying it into Internet of vehicles is discussed.…”
