| 1 | Cryptanalysis of efficient proxy signature schemes for mobile communication显示文摘In a proxy signature scheme, an original signer is allowed to delegate his signing power to a designated person, called the proxy signer and the proxy signer is able to sign the messages on behalf of the original signer. Recently, Lu, Dong and Cao proposed two proxy signature schemes for mobile communication (see Sci China Ser F-Inf Sci, 2008, 51(2): 183–195). Although they proved that their schemes are secure in the random oracle model, we disprove their claim and show that their schemes are not secure. | LI FaGen SHIRASE Masaaki TAKAGI Tsuyoshi | 2010 | Science China(Information Sciences)2010，53，10： | 6 |
| 2 | Efficient and Provably Secure Multi-Recipient Signcryption from Bilinear Pairings显示文摘Signcryption is a cryptographic primitive that performs signature and encryption simultaneously, at lower computational costs and communication overheads than the signature-then- en- cryption approach. In this paper, we propose an efficient multi-recipient signcryption scheme based on the bilinear pairings, which broadcasts a message to multiple users in a secure and au- thenticated manner. We prove its semantic security and unforge- ability under the Gap Diffie-Hellman problem assumption in the random oracle model. The proposed scheme is more efficient than re-signcrypting a message n times using a signcryption scheme in terms of computational costs and communication overheads. | LI Fagen HU Yupu LIU Shuanggen | 2007 | Wuhan University Journal of Natural Sciences2007，12，1： | 5 |
| 3 | An Efficient Identity-Based Anonymous Signcryption Scheme显示文摘Signcryption is a cryptographic primitive that performs encryption and signature in a single logical step more efficiently than signthen-encrypt approach. Till now, various kinds of signcryption schemes have been proposed. Among them, the requirement of signcrypter’s privacy protection is needful in some practical applications. In this paper, a new identity-based anonymous signcryption scheme from bilinear pairings, which is the organic combination of identity-based ring signature and encryption scheme, is proposed. The proposed scheme is indistinguishable against the chosen ciphertext attack under the Decisional Bilinear Diffie-Hellman assumption in the random oracle model. Its unforgeability relies on the computational Diffie-Hellman problem. Compared with the previous schemes, the new scheme is more efficient in computation. | YU Yong LI Fagen XU Chunxiang SUN Ying | 2008 | Wuhan University Journal of Natural Sciences2008，13，6： | 4 |

| 6 | Preparation of WO3 thin films by dip film-drawing for photoelectrochemical performance显示文摘Here we report the WO3 thin films on F-doped SnO2 conducting glass (FTO) substrates which were prepared by using dip film-drawing method. Dip film-drawing was a simple, convenient, economical method and in largescale to prepare photoanodes for future applications. The FTO substrates were dipped in tungstic acid solution then film-drawn included 3, 6, 9, 12 and 15 times for prepared different thicknesses of WO3 thin film photoanodes. Then the photoa no des were employed as the electrodes in photoelectrochemical property Keywords: WO3 thin films Dip film-drawing Photoelectrochemical Thicknesses Large-scale measurements, which include scan linear sweep, repeated on/off illumination cycles, electrochemical impedanee spectroscopy and incident phot on to current conversion efficiency, respectively. The results showed that the WO3 thin films dipped 9 times with 175 nm thicknesses had the best photoelectrochemical performance of 0.067 mA·cm^-2 at 1.23 V versus RHE. | Dongbo Xu Lili Li Weiqiang Fan Fagen Wang Hongye Bai Baodong Mao Weidong Shi | 2019 | Chinese Journal of Chemical Engineering2019，27，5： | 1 |

| 20 | Entangled chimeras in nonlocally coupled bicomponent phase oscillators:From synchronous to asynchronous chimeras显示文摘Chimera states,a symmetry-breaking spatiotemporal pattern in nonlocally coupled identical dynamical units,have been identified in various systems and generalized to coupled nonidentical oscillators.It has been shown that strong heterogeneity in the frequencies of nonidentical oscillators might be harmful to chimera states.In this work,we consider a ring of nonlocally coupled bicomponent phase oscillators in which two types of oscillators are randomly distributed along the ring:some oscillators with natural.frequency w1 and others with w2.In this model,the heterogeneity in frequency is measured by frequency mismatch|w1-w2|between the oscillators in these two subpopulations.We report that the nonlocally coupled bicomponent phase oscillators allow for chimera states no matter how large the frequency mismatch is.The bicomponent oscillators are composed of two chimera states,one supported by oscillators with natural frequency wI and the other by oscillators with natural frequency w2.The two chimera states in two subpopulations are synchronized at weak frequency mismatch,in which the coberent oscillators in thern share similar mean phase velocity,and are desynchronized at large frequency mismatch,in which the coherent oscillators in different subpopulations have distinct mean phase velocities.The synchronization-desynchronization transition between chimera states in these two subpopulations is observed with the increase in the frequency mismatch.The observed phenomena are theoretically analyzed by passing to the continuum limit and using the Ott-Antonsen approach. | Qiong-Lin Dai Xiao-Xuan Liu Kai Yang Hong-Yan Cheng Hai-Hong Li Fagen Xie Jun-Zhong Yang | 2020 | Frontiers of physics2020，15，6： | 0 |
