The invention discloses a processing method of time delay calling. The processing method is based on a system. The system comprises a plurality of signaling information detecting and processing devices connected with a relevant number seven signaling link or an IP signaling link and a time delay processing platform connected with a signaling network. The processing method comprises the following steps. A signaling information screening step is performed, the signaling information detecting and processing devices detect and process signaling information which runs through, and relevant information which is called out is screened on the time delay platform through the signaling network. A calling time delay processing step is performed. The time delay processing platform sends called initial address information to a called end office in a time delay mode based on preset service rules and authentication on calling number information, and meanwhile, sends back verified information to a calling end office immediately. The processing method of time delay calling can be performed by being independent of existing communication networks and can avoid upgrading of a node switching device. The function of providing a blacklist and a whitelist is achieved, and in addition, unreasonable calling is effectively limited in a calling process through a time delay continuous method.

The invention discloses a process industry white list access method and system based on identity authentication. The method comprises the steps: starting white list software, and obtaining all operator user lists on a computer through the white list software; making a white list record, and scanning software used on a computer to be included in a white list; in the process that the administrator makes the white list record, correspondingly matching the data in the white list record with an operator; when the operator uses the software used on the computer, obtaining the identity of the operator by the white list software and judging whether the software used on the computer is in the white list record or not. The problems that an existing industrial white list is tedious in generation and rough in management are solved.

The invention relates to a lattice anti-key abuse attribute encryption method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining an access request of a user, and embedding an encryption identifier of user identity information into a user private key to form a key; judging whether the secret key is leaked or not; if the secret key is leaked, the user ID in the leaked secret key is calculated, the user ID is revoked from the white list, and access is terminated. According to the method, on the basis of realizing key tracking and key delegation abuse resistance, complex bilinear operation is avoided, and compared with an attribute encryption scheme on LWE, the efficiency is higher, the overhead is smaller, and the requirements can be better met.
