Abstract: Various examples are directed to systems and methods using a database management system. The database management system may generate a root certificate for a database host of the database management system and a first host certificate using the root certificate. The database management system may receive, from a first client associated with the first tenant, a request to access the root certificate stored at a root certificate storage location and send the root certificate to the first client. The database management system may receive, from the first client, a request to establish a secure communication connection. The secure communication connection with the first client may be established at least in part by providing the first host certificate to the first client.

Abstract: A LIDAR system. The LIDAR system includes a light transmitting unit and a light receiving unit. A beam path is formed between the light transmitting unit and the light receiving unit of the LIDAR system, in order to optically scan surroundings of the LIDAR system during the operation of the LIDAR system. The LIDAR system is configured to recognize a contamination of the beam path, based on LIDAR measured data, which have been obtained during the optical scanning of the surroundings. A method for recognizing a contamination of a beam path of a LIDAR system is described, including recognizing the contamination by the LIDAR system based on LIDAR measured data, which have been obtained during an optical scanning of surroundings of the LIDAR system.
