  • Cryptanalysis of HuangChang partially blind signature scheme

    Fangguo Zhang   Xiaofeng Chen  

    Partially blind signature is an extension of blind signature that allows a signer to sign a partially blinded message that include pre-agreed information such as expiry date or collateral conditions in the resulting signatures. It is more useful than blind signature in many applications, such as electronic cash (e-cash) system. Recently, Huang and Chang proposed a new design of efficient partially blind signature scheme. However, in this paper, we show that Huang-Chang partially blind signature scheme is not secure, this scheme does not meet the basic property of a partially blind signature, partial blindness: a malicious user (requester) can prepare a special public information a' and then remove the original information a from the signer's signature to obtain a signature with this special information.

    A smart home device control method, apparatus and device, and a non-volatile computer storage medium. The method comprises: acquiring input information input by a user based on a natural dialogue mode interface (S101); obtaining a control instruction for a smart home device according to the input information (S102); and sending the control instruction to the smart home device, so as to enable the smart home device to execute an operation according to the control instruction (S103). Due to the fact that a natural dialogue mode interface is adopted as the mode of interaction with a user, there is no need to display all controllable controls, of the smart home device provided by an application on a screen of a terminal. Therefore, the problem of increased data interaction between an application and a processing engine used by the application due to the limited display area of the terminal in the prior art can be avoided, and accordingly the processing burden of the processing engine is reduced.

  • Preparation of CeO2 micro/nanostructure and their photocatalytic properties in glow discharge electrolysis

    Huang, Chang   Wu, Xiaoqing   Ren, Wei   Shi, Peng  

    Abstract It is well known that CeO2 is a key commercial catalyst with a correlation to morphology and size, and the glow discharge electrolysis (GDE) is an advanced oxidation process to treat wastewater. In this article, CeO2 nanodots and shuttle-shaped rods were prepared by the sol–gel method and the homogeneous precipitation method, respectively. The average diameter of the nanodots is about 10 nm, while the diameters and the lengths of the rods are 500 nm and 1–5 μm. The effect of CeO2 sample on decoloration rate of methyl orange (MO) was investigated in the GDE system. Experimental results indicated that the decoloration rates of MO were increased after adding two kinds of CeO2 photocatalysts. Furthermore, the decoloration rates of MO catalyzed by shuttle-shaped CeO2 rods were higher than that catalyzed by CeO2 nanodots. It is demonstrated that UV-light generated in the process of GDE can activate CeO2 photocatalyst, and the morphology and size of CeO2 have influence on its catalytic performance. This method can be considered in the treatment of dye wastewater.
