Abstract: The invention relates to a method (300) for operating an industrial network (100). The industrial network (100) has at least one network device (101), which can be actuated by a central control device (103), and a local interface (102) for locally accessing (A) the network device (101). The method has the following steps: transmitting (301) an access request (Q) for locally accessing (A) the network device (101) via the local interface (A) to the central control device (103); authenticating (302) the access request (Q) by means of the central control device (103); and setting up (304) the local interface (102) by means of the central control device in order to locally access (A) the network device (101) on the basis of the access request (Q). The invention further relates to a corresponding industrial network. By using the proposed method and the proposed industrial network, access to the network device can be configured more efficiently and without loss.

Abstract: A computer implemented method, computer program product, server and clients for preserving privacy and accountability. The server receives from a first client computer pseudonymous, encrypted data and stores the pseudonymous, encrypted data. The -server further receives receiving at from a second client computer a data request for the pseudonymous, encrypted data and provides the pseudonymous, encrypted data to the second client computer in response to the data request. The server receives from the second client computer a signed key request for at least one key, wherein the at least one key is configured to decrypt the pseudonymous, encrypted data and wherein the signed key request comprises a public key of the second client computer. The server receives from the first client computer the at least one key, wherein the at least one key is encrypted with the public key of the second client computer and provides the at least one encrypted key to the second client computer in response to the signed key request.
