AES128 encryption and Challenge Reponse authentication

The NEOCORTEC Mesh Network technology has features build into the core of the protocol stack which makes it very secure and reliable. To make sure payload data or network communication in general can not be monitored by an untrusted entity, all wireless communication between the nodes is encrypted using AES128. To prevent playback attacks, each payload data exchange between a source node and a sink node, is protected with a challenge-response mechanism that will make it impossible to simply record a previous transmission, and re-transmit it again. This without adding transmission latency.

Local and end-to-end ACK/NACK

In addition to the security features, there are a number of features which helps to increase the reliablity of the data transmission: Local ACK/NACK ensures that when the payload data travels from one node to the next, it is ensured that the sending node gets notified whether the transmission was successful or not. End-to-end ACK/NACK ensures that once the payload data has been delivered at the sink node, an acknowledgement package is routed back to the source node. This acknowledgement is delivered to the application layer. Alternatively, if the payload data did not reach its destination before the user programmable timeout period has been reached, a non-acknowledge will be generated by the protocol stack and delivered to the application layer. All this happens “under the hood”, and the application layer does not need to worry about it.

Avoiding Radio Noise

To fight radio noise – be it noise in general or communication signals from other technologies operating in the same unlicensed frequency band – Frequency Hopping Spread Spectrum is used to spread the transmission evenly in the frequency band. Each node has its own randomly selected hopping scheme, which means that it will transmit on a new channel each time it transmits.
