Key path analysis method for large-scale industrial control network by Yaofang ZHANG, Zheyu ZHANG, Haikuo QU, Ge ZHANG, Zibo WANG, Bailing WANG

“…In order to solve the problem of high time-consuming and resource-consuming quantitative calculation of large-scale industrial control network attack graphs, a key path analysis method for large-scale industrial control networks was proposed.Firstly, the idea of cut set was used to calculate the key nodes set of Bayesian attack graph by combining the atomic attack income in industrial control network, which solved the problem that the current cut set algorithm only considers the key nodes in graph structure.Secondly, a dynamic updating strategy of Bayesian attack graph which only updated the attack probability of key nodes was proposed to efficiently calculate the attack probability of the whole graph and analyze the key path of attack graph.The experimental results show that the proposed method can not only ensure the reliability of the calculation results of large-scale industrial control attack graphs, but also can significantly reduce the time consumption and have a significant improvement in the calculation efficiency.…”

A roadmap from the bond strength to the grain-boundary energies and macro strength of metals by Xin Li, Hao Wu, Wang Gao, Qing Jiang

“…Motivated by the role of grain boundaries in the strength of metals, we introduce a predictive model to determine the grain-boundary energies and strength of metals from the cohesive energy and atomic radius. This scheme originates from the d-band characteristics and broken-bond spirit of tight-binding models, and demonstrates that the repulsive/attractive effects play different roles in the variation of bond strength for different metals. …”

Adaptor signature scheme based on ISRSAC digital signature algorithm by Yanshuo ZHANG, Ning LIU, Yuqi YUAN, Yatao YANG

“…The adapter signature scheme can provide good properties of atomic exchange in the block chain, and has been widely used in practice.A new adapter signature scheme was constructed based on a digital signature algorithm for improved security of RSA cryptosystem (ISRSAC).After proving that the proposed scheme satisfied the correctness of the pre-signature, unforgeability, adaptability of the pre-signature, extractability of the evidence and the security of the signature scheme, it was compared with the adapter signature scheme based on the SM2 digital signature algorithm, the Schnorr-based adapter signature scheme and the ECDSA-based adapter signature scheme.And these schemes were analyzed in terms of time overhead and main calculation amount.The analysis results show that the proposed scheme is similar to other schemes in terms of time overhead, but the proposed scheme expands the application scenarios of ISRSAC algorithm in the current environment, and through the combination of ISRSAC algorithm and adapter signature technology, the selection of adapter signature is more flexible and can have a wider range of applications.…”
