The invention discloses a searching method for an impossible differential path of a related key of a block cipher. As an impossible differential attack method and a related key attack method are combined, the problems of automatic searching of the impossible differential path of the related key and searching of a longest analysis path in cryptanalysis are solved, and deeper and more thorough analysis for a cryptographic algorithm can be carried out. According to the searching method for the impossible differential path of the related key of the block cipher, the method for searching the impossible differential path of the related key is upgraded from the traditional manual analysis to computer automatic searching, the disadvantages that an existing manual analysis method is fussy and error-prone when being used for analyzing the cryptographic algorithm are avoided, the maximum length of the impossible differential path of the related key of the block cipher algorithm can be calculated rapidly and accurately, and the cryptanalysis efficiency is improved. The searching method for the impossible differential path of the related key of the block cipher realizes transformation of the cryptographic algorithm from a non-generalized Feistel structure to a generalized Feistel structure, can be widely applied to automatic search of the impossible differential paths of related keys of various cryptographic algorithms in different structures.

The invention relates to a Web3D encryption method based on a dongle, in particular to a data encryption method through the USB (Universal Serial Bus) dongle under the condition of low costs. According to the encryption method, the whole Web3D operation interface is subjected to encryption protection by utilizing the USB dongle, namely, a user can perform a three-dimensional interactive operation on a browser only when the dongle is inserted into a client server, as long as no dongle is detected, the interface is locked, so that illegal embezzlement and access of data is prevented. Compared with other specialized dongles, ordinary dongles has low price. Besides, the Web3D encryption method based on the dongle is applicable to Web3D files of different formats and flexible.

The invention discloses an advertisement pushing and intelligent screening intelligent wardrobe control method. The advertisement pushing and intelligent screening intelligent wardrobe control method comprises the steps of (1) determining the age and gender of a user through a face recognition system of an intelligent wardrobe, (2) positioning environmental factors through the intelligent wardrobe, (3) by combining the age and gender of the user with the positioned environmental factors, pushing advertisement on the display screen of the intelligent wardrobe.

The invention relates to the field of municipal public facilities, in particular to a well lid with a safety warning device. The well lid with the safety warning device comprises the well lid, the warning device and a support device; connecting rods connected with a well wall are arranged on two sides of the support device; the warning device is mounted between the well lid and the support device; the warning device includes a warning box; a compressed gas box is arranged at the bottom of the warning box; a separation plate for stopping gas leakage is arranged at the upper part of the compressed gas box; a through hole connected with the compressed gas box is formed in the middle position of the separation plate; extension springs are arranged on two sides of the upper part of the separation plate; a slide plate is arranged at the upper parts of the extension springs; a lifting rod matched with the through hole is arranged in the middle position of the slide plate; and an exhaust port is formed in the outer side between the separation plate and the slide plate, and is connected and provided with a warning airbag. The device prevents loss of the well lid and accidental falling of pedestrians and vehicles into a pit, and reduces the danger.
