Zusammenfassung:A non-transitory, computer-readable medium, comprising instructions that when executed by one or more processors, cause the one or more processors to perform operations that include receiving a request to connect to the wireless access point from a computing device. The request includes a private key. The operations may also include comparing the private key to an index of public keys associated with respective users authorized to connect to the wireless access point, determining that the computing device is authorized to connect to the wireless access point based on the comparison, authorizing the computing device to connect to the wireless access point, encrypting maintenance data associated with one or more industrial automation devices, and transmitting the encrypted maintenance data to the computing device via the wireless access point.
