Summary
Sertainty UXP encryption is feasible for LoRaWAN IoT security, enhancing data protection despite adding overhead. This solution offers a viable path for securing resource-constrained networks with careful implementation.
Area of Science:
- Internet of Things (IoT) security
- Wireless communication protocols
- Cryptography and data encryption
Background:
- LoRaWAN (Long Range Wide Area Network) offers low-power, long-range communication but has security vulnerabilities, particularly with AES-128 in ECB mode.
- Sertainty UXP (Unbreakable Exchange Protocol) uses AES-256-GCM for authenticated encryption with data-level access control, suitable for sensitive IoT data.
Purpose of the Study:
- To evaluate the feasibility and performance of Sertainty UXP encryption within LoRaWAN's payload and performance constraints.
- To compare UXP's overhead and effectiveness against other encryption algorithms like ASCON-128, SPECK, and XTEA.
Main Methods:
- Implemented and compared AES-256-GCM (UXP), ASCON-128, SPECK, and XTEA encryption algorithms.
- Encrypted smart meter data and transmitted it over LoRaWAN using a LoRa-E5 development board.
- Evaluated system performance based on latency, payload size, and message integrity, with payload splitting for LoRaWAN compatibility.
Main Results:
- Integrating Sertainty UXP encryption into LoRaWAN is technically feasible.
- UXP integration introduces additional overhead and latency compared to simpler encryption methods.
- Payload splitting and reassembly were necessary to meet LoRaWAN transmission constraints.
Conclusions:
- Sertainty UXP offers enhanced end-to-end IoT security by embedding robust encryption and controls directly into data objects.
- UXP presents a viable, forward-looking solution for securing resource-constrained networks like LoRaWAN.
- Successful implementation requires careful management of trade-offs between security strength and transmission efficiency.

01:21Pilot and Numeric Relaying
533
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:27Line Protection with Impedance Relays
500
Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.

715
Directional relays, essential for managing unidirectional fault currents, enhance the safety and efficiency of power systems. On power lines equipped with directional relays, faults downstream (to the right) of the current transformer typically cause the fault current to lag the bus voltage by approximately 90 degrees, known as the forward direction. In contrast, upstream (left-side) faults may result in the fault current leading the bus voltage by nearly 90 degrees, termed the reverse...

00:59Propagation of Uncertainty from Random Error
2.2K
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

01:25Network Function of a Circuit
995
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

00:59Uncertainty: Overview
1.9K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.
