    Cost analysis of stratospheric albedo modification delivery systems by Justin McClellan, David W Keith, Jay Apt

    Published 2012-01-01
    “…We conclude that (a) the basic technological capability to deliver material to the stratosphere at million tonne per year rates exists today, (b) based on prior literature, a few million tonnes per year would be sufficient to alter radiative forcing by an amount roughly equivalent to the growth of anticipated greenhouse gas forcing over the next half century, and that (c) several different methods could possibly deliver this quantity for less than $8B per year. …”

    Efficiently Secure Architecture for Future Network by YANG Xin, LI Hui, QUE Jianming, MA Zhentai, LI Gengxin, YAO Yao, WANG Bin, JIANG Fuli

    Published 2023-03-01
    “…Traditional IP-based Internet offers an end-to-end data transport service and has developed rapidly in the past half-century.However,serious security incidents emerged from attacks based on traditional networks.Traditional security mechanisms(e.g.,firewalls,intrusion detection systems) enhance security.However,most of them only provide some remedial strategies rather than solve the address-security problem radically due to the lack of change in network design.The overall in-depth security of the networked system cannot be guaranteed without a fundamental change.In order to meet the development requirements of the next generation of an endogenous security network,one of the future networks,the multi-identifier network(MIN),is introduced as our research background.This paper proposes an efficient scheme in hieratical architecture that provides comprehensive protection by addressing the security aspects pertaining to the network and application layers.At the network layer,the proposed architecture develops a multi-identifier routing scheme with embedded identity-based authentication and packet signature mechanisms to provide data tamper-resistance and traceability.At the application layer,the proposed architecture designs a mimic defensive scheme combined with weighted network centrality measures.This scheme focuses on protecting the core components of the whole network to improve the service's robustness and efficiently resist potential attacks.This paper tests and evaluates the proposed scheme from a theoretical and practical perspective.An analytical model is built based on the random walk for theoretical evaluation.In experiments,the proposed scheme is developed in MIN as MIN-VPN.Then considering IP-VPN as a baseline,anti-attack tests are conducted on IP-VPN and MIN-VPN.The results of theoretical evaluations and experiments show that the proposed scheme provides excellent transmission performance and successful defense against various TCP/IP-based attacks with acceptable defensive cost,demonstrating this security mechanism's effectiveness.In addition,after long-period penetration testing in three international elite security contests,the proposed method is effectively immune to all TCP/IP-based attacks from thousands of professional teams,thus verifying its strong security.…”
