Digital keys are a core concept in establishing secure networks, one as relevant in a data center application as it is at the edge of the tactical battlefield. While cryptography (crypto) uses both symmetric and asymmetric keys for different functions, for this column we’ll focus on asymmetric cryptography in which different keys are used for locking and unlocking.
The vision of hardware interoperability at the tactical edge, from air platforms to ground vehicles to base stations, is now being realized. Because MOSA [modular open systems approach] is an approach and not itself a standard, solutions that support this vision can be achieved through many different means as long as interfaces and communications protocols are based on open standards. There remains a key area to address, though, to achieve seamless interoperability between heterogeneous systems. Consider, for example, the Sensor Open Systems Architecture (SOSA) Technical Standard: While most aspects of sensor processing system architectures are well-defined within SOSA, one area that has not been rigidly defined is the network configuration and operational environment of individual cards and modules.
A software-defined WAN (SD-WAN) can establish a data fabric capable of dealing with any tactical edge scenario where reliable WAN is needed.
