Abstract: A computer-implemented method for error-correction-encoding and encrypting of a file is provided. The file is split into at least two blocks. The first block is encrypted using a given encryption key. The encrypted first block is encoded twice using a first and second forward error correction code of the first block. Each subsequent block is encrypted by performing an algebraic operation. The encrypted block is encoded twice using a first and second forward error correction code for this block, wherein a cryptographic indexing function provides a set of indices used by the second forward error correction code to produce the second encoded chunk. The first encoded chunks of each encrypted block are outputted. The computer-implemented method enables secure transmission of a file content between low power devices.

Abstract: A method for checking a license for the usage of at least one performance property in an Internet of things device, is provided, having the steps of—ascertaining at least one license condition for the usage of the performance property of the IoT device by at least one attribute contained in a license identifier, —transmitting and storing the license identifier, —checking the license condition by a) generating a pseudo-access which is assigned to the performance property using a pseudo-holding unit and b) checking an authorization for the pseudo-access by checking the attribute of the license identifier using a verification unit, and—activating the at least one performance property if the pseudo-access is confirmed, wherein the license identifier, the pseudo-holding unit, and the verification unit are designed based on a specification for verifiable credentials.

Abstract: Provided is a network adapter for unidirectional transmission of a user data stream to a bidirectional network interface, the network adapter including: a first connection unit which is physically connected to a bidirectional network interface of a first device; a second connection unit which is physically connected to a bidirectional network interface of a second device; and a terminating unit which has at least one bit transmission module and which is designed to establish a bidirectional data link to the network interface of the first device, to receive the user data stream from the first device exclusively in a unidirectional fashion via the data link, and not to send a user data stream to the first device.

Abstract: Provided is a method for decoupled transmission of data between networks having different security requirements, in which, in a first network having high security requirements, first data from a first application are transmitted in a communication exclusively between components within the first network via multiple communication links, data being captured in the first network by at least one monitoring device per communication link in a decoupled manner and being transmitted to a second network having lower security requirements. Also, a corresponding arrangement is also provided.

Abstract: A one-way coupling device for the feedback-free transmission of data from the first network with high security requirements into a second network with low security requirements, containing a request unit, an eavesdropping unit and a receiving unit, wherein the request unit is formed so as to provide a first communication link within the first network to at least one device and, moreover, to request first data from the at least one device and then to transmit the first data via a second communication link on a separate line loop of the request unit, and the eavesdropping unit, which is formed so as to eavesdrop on data on the separate line loop and to transmit data to a receiving unit which is arranged in the second network. Also, a corresponding request unit, a corresponding method and a corresponding computer program product is also provided.
