Disclosed are a mimic defense system based on certificate identity authentication, and a certificate issuing method. Said system comprises an underlying device, an intermediate controller and a certificate issuing center, the intermediate controller and the certificate issuing center being respectively provided with a unique certificate, a public key of each certificate being stored in the certificate, and a corresponding private key being stored privately by each device and being not disclosed to the outside. In said method, a device sends a certificate request file to an intermediate controller; after verifying the identity, the intermediate controller applies for a certificate to a certificate issuing center; after issuing the certificate, the certificate issuing center sends the certificate to an underlying device by means of the intermediate controller; and the underlying device installs the certificate. The intermediate controller using a mimic structure in the present invention can effectively defense attacks from attackers, and during the work of a determination module, if output results of heterogeneous executors are inconsistent, the determination module can also determine in time whether the heterogeneous executors are attacked, and maintain and repair the system in time.

[TANG LIANG, CHEN ZHONGLIN, TANG MING, CHEN ZONGYOU, JIANG YUNSHENG, TANG ZHANKUN, ZOU RONG, JIANG LIQUAN] CN;CN The invention discloses a method for preparing high-quality golden Sophora japonica tea with Flos Sophorae Immaturus original color. Flos Sophorae Immaturus of golden Sophora japonica seedling trees are used as raw materials, so the quality of the raw materials is well controlled. The steps of fixation-cooling-stirring-secondary cooling-secondary stirring-tertiary cooling are adopted to avoid the loss of original colors of Flos Sophorae Immaturus under steaming resulted by the continuous long-term high-temperature treatment of Flos Sophorae Immaturus with high moisture. The key steps are carried out on machines, which has strong operability and can realize industrial production. The golden Sophora japonica tea made by this method is bright green and fresh, with excellent appearance; the tea soup is yellow green, and tastes full of fragrance; the golden Sophora japonica tea enriches the existing varieties of Sophora japonica tea and meets the needs of different consumer groups, which has good practical significance.
