Embodiment Construction

[0041] Embodiments of the invention described herein can be used to build nodes with low memory and / or processing requirements. By providing a secret value on a first channel to be used in communications on a second channel, access can be restricted to units that have physical access to the node. A different random value can be used for each message to prevent replay attacks. The instructions can be hashed together with secret and random values ​​to enable nodes to verify them in a resource efficient manner such that, for example, there is no need to implement encrypted communication protocols such as Transport Layer Security (TLS).

[0042] figure 1 An example system capable of supporting at least some embodiments of the invention is shown.figure 1 The system includes device 110, which may include, for example, a smart phone, cellular phone, tablet device, handheld device, laptop or desktop computer, or other suitable electronic device. Device 110 may include a user interfa...

Abstract

In accordance with an example aspect of the present invention, there is provided an apparatus comprising at least one receiver configured to receive, via a first channel, a secret value and an identifier of a local node and, via a second channel, a random value, and at least one processing core configured to cause transmission to the local node of a first message comprising a hash value, the hash value being derived based on a set comprising the secret value, the random value, and an instruction.

Description

technical field [0001] The invention relates to the field of signal transmission between electrically operated devices for controlling these electrically operated devices. Background technique [0002] Interaction with a distributed system can occur in various ways. In an Ethernet network, for example, devices are interconnected through the network and are accessible to each other in a direct manner. In the Internet, by contrast, messaging between devices can occur using the Internet Protocol (IP), addressing, and domain names. For example, a node may query for an IP address of a desired corresponding node based on a known domain name. Such queries may be made to the Domain Name System (DNS). Changing IP addresses can even be handled without interrupting the connection by updating to DNS. [0003] A sensor network may include sensor nodes interconnected with each other. The sensor nodes may be configured to communicate with each other and provide sensor information to f...
