Zigbee technology introduction Zigbee is wireless PAN (Personal Area Network) technology developed to support automation, machine-to-machine communication, remote control and monitoring of IoT devices. It evolved from IEEE 802.15.4 wireless standard and supported by the ZigBee Alliance. IEEE 802.15.4 standard determines specifications for the physical and data link layer and Zigbee Alliance provides standards from network layer to application layer. While Zigbee determines the contents of the transmitted message, the 802.15.4 standard provides details about the robust radio communication and medium access control. The Zigbee Alliance, as a non-profit association, develops open global Zigbee standard for use in the Internet of Things...

I get accused of focusing too much on 5G as the only future IoT connectivity option. I do write a lot about how 5G will revolutionize our society, become the most critical of critical infrastructures and about security threats with 5G. I see 5G, with its low latency, high bandwidth, network slicing and ubiquitous coverage becoming the foundational capability for mission critical industrial, agricultural, financial, medical, education, energy and transportation, even military and emergency services IoT communication needs. That’s not to say that 5G is the only IoT connectivity option. There are plenty of others. IoT applications have some common requirements...

Quantum computing holds the potential to revolutionize fields where classical computers struggle, particularly in areas involving complex quantum systems, large-scale optimization, and cryptography. The power of quantum computing lies in its ability to leverage the principles of quantum mechanics—superposition and entanglement—to perform certain types of calculations much more efficiently than classical computers.

Ultra high speed, high quality 5G networks are expected to provide the connectivity required for massive IoT adoption, remote robotic surgery as well as instant movie downloads and 3D mobile gaming. The technology boasts incredible reliability and low latency and promises to enable the next industrial revolution and society 5.0. Assuming that 5G policy and regulatory issues are sorted out. However, recent hype generated by mobile operators and false promises inevitably mean that unreasonable early expectations will go unmet. So far, China and Huawei have out-competed Americans in development and deployment of 5G technology. The Trump Administration is keenly aware...

Hyped as the technology that will transform the world, 5G is moving past the buzzword stage with first implementations coming to life in 2019. Nations are racing to 5G with such fervor that it now became one of the hottest hot-button geopolitical issues. With latency as low as 1 ms and speeds of up to 4 Gbps, as well as a wider range of frequency bands and enhanced capacity, 5G will be able to accommodate innovative use cases and much greater numbers of connected devices, driving overall growth for Internet of Things (IoT). In addition to the speed and capacity improvements,...

Don’t let the “5G” in the title confuse you. This post is not only about the telcos’ core networks, but about the 5G security and privacy issues in our (very) near, and very different future that 5G will enable. In the 5G-enabled massive Internet of Things (mIoT) world we’re about to find ourselves in, we are expected to have 1000 devices connected for every person… These devices will be the components of the ‘5G operating system’ for our smart cities, our industry 4.0, our smart homes, smart transportation, smart healthcare, and much more. To enable this future, we will...

Cryptographic systems rely on the unpredictability and randomness of numbers to secure data. In cryptography, the strength of encryption keys depends on their unpredictability. Unpredictable and truly random numbers—those that remain secure even against extensive computational resources and are completely unknown to adversaries—are among the most essential elements in cryptography and cybersecurity.

Quantum Artificial Intelligence (QAI) represents an emerging frontier where quantum computing meets artificial intelligence. This interdisciplinary field explores how quantum algorithms can enhance, accelerate, and expand the capabilities of conventional AI systems. Quantum computing's potential to process complex datasets exponentially faster than classical computers could revolutionize areas like machine learning, optimization, and pattern recognition.

The intricate giant chandelier of copper tubes, wires, and shielding often leaves people puzzled and curious. This image of a quantum computer is quite striking and unlike any classical computer we've seen before. This unique appearance is not just for show; it's a direct result of the specific technological requirements needed to operate quantum computers, particularly those based on superconducting qubits.

Fidelity in quantum computing measures the accuracy of quantum operations, including how effectively a quantum computer can perform calculations without errors. In quantum systems, noise and decoherence can degrade the coherence of quantum states, leading to errors and reduced computational accuracy. Errors are not just common; they're expected. Quantum states are delicate, easily disturbed by external factors like temperature fluctuations, electromagnetic fields, and even stray cosmic rays.

Cybersecuring railway systems from potential attackers must become paramount in the digitization that those systems currently undergo. Their cybersecurity is too closely interlinked with the railway safety to leave the door open to disruption. To make matters worse, they are increasingly being targeted. Railway systems have long been critical. Mass transit systems move hundreds of thousands of people throughout urban areas each work day. Freight systems move an estimated 40 tons of freight for every person in the U.S. every year. Imagine the chaos if they were disrupted. These systems have always been challenging to secure. Even urban mass transit systems...

As IoT adoption continues to proliferate, manufactures and adopters are increasingly aware of cybersecurity risks to IoT. Yet, even among the IoT security professionals, one significant potential remote attack vector is often overlooked: intentional electromagnetic interference (IEMI). Electromagnetic interference (EMI) surrounds us – natural causes, such as solar flares and lightning; and man-made sources such as radio and TV broadcasting, radars, microwaves and many others all emit electromagnetic waves that could disrupt operation of electrical and electronic devices. That is, if devices wouldn’t comply with numerous electromagnetic compatibility (EMC) standards which ensure correct operation in common electromagnetic environment and resilience...

While Stuxnet is gone, the world now knows what can be accomplished through cyber-kinetic attacks. As we approach the 10th anniversary of when Stuxnet was (likely) deployed, it is worthwhile to examine the effect it still has on our world. As the world’s first-ever cyberweapon, it opened Pandora’s box. It was the first true cyber-kinetic weapon – and it changed military history and is changing world history, as well. Its impact on the future cannot be overstated. Stuxnet’s beginnings Stuxnet is believed to have been conceived jointly by the U.S. and Israel in 2005 or 2006 to cripple Iran’s nuclear weapon development...

In their growing efforts to increase efficiencies through digitization and automation, railways are becoming increasingly vulnerable to cyber-kinetic attacks as they move away from strictly mechanical systems and bespoke standalone systems to digital, open-platform, standardized equipment built using Commercial Off the Shelf (COTS) components. In addition, the increasing use of networked control and automation systems enable remote access of public and private networks. Finally, the large geographical spread of railway systems, involving multiple providers and even multiple countries, and the vast number of people involved in operating and maintaining those widespread systems offer attackers an almost unlimited number of attack...

As our cities, our transportation, our energy and manufacturing – our everything – increasingly embrace Internet of Things (IoT) and Industrial Controls Systems (ICS), securing its underlying cyber-physical systems (CPS) grows ever more crucial. Yet, even among engineers and cybersecurity specialists, one potential attack trajectory is often overlooked: Intentional Electromagnetic Interference (IEMI). ICS and IoT – digital systems that run today’s modern society – rely on changes in electrical charges flowing through physical equipment. Creating the 1s and 0s of which all digital information is composed requires electronic switching processes in circuits. The current used in this process is not...
