Security is a very important key matter in any kind of communication, either wired or wireless. At Reicom we dominate the entire communication stack of our radio, hence we have implemented strong security mechanisms at every communication level.

Typically, the majority of the communication systems adopt coding and encryption mechanisms at the transport layer (layer 4 of ISO-OSI model) to protect the transmission of the data, trying to mask them by making them unreadable and complex (i.e. payload encryption).
Other systems go beyond this and try to encode also the lower layers,  generally down to layer 2. It is clear that this effects also the upper layers, above all if the network is a real dynamic hybrid MESH one, in which the addresses of the sender and receiver are not necessarily known in advance.

Today encryption algorithms are based on the knowledge of specific encryption keys and in some cases on their exchange too. These algorithms are normally coded in the communication stack. At Reicom, we have implemented them starting from layer 2 (HSBRA™) up to the higher layers (Clancast™). But... we do more.

HSBRA™ plays an important role: it manages, directly at the hardware level, both MAC radio datagrams encryption (Layer 2 of the ISO-OSI model) and shadowing and masking of each single LLC trunks (Layer 1 of the ISO-OSI model).  It is a unique strong and reliable security solution that acts both on the data transmitted and on the way in which these data are transmitted, down-to the lower physical layer (usually adopted for military and defense application or whenever security is a strong issue)

The strong coding and encryption of the data flowing into the network, combined with a proper coding of the radio datagrams at MAC level directly into the Baseband, solves two important issues of the communication networks:

• Protection of the “digital” identity of every single transceiver (radio node)
• Guaranteed identification of every single transceiver (radio node)

Thanks to coding and encryption algorithms implemented into the HSBRA™ and managed, at higher layers, by the Clancast™ communication stack, the MAC addresses of every radio transceiver are implicitly protected from sniffing attempts (interception and passive acquisition of the data in transit between two nodes or into the entire network), spoofing attempts (identity falsification) and snooping attempts (unauthorized access to third party data and information).

Beyond this, Reicom SDR radio supports hardware based coding and encryption algorithms that, in real time, scramble and encrypt data using state of the art solution like AES 128 and 256 bit encryption, as well as MIL compliant data scramble encoding engine.
