Abstract

Since Rijndael algorithm was selected as the Advanced Encryption Standard (AES) by NIST, optimization research for the AES has been actively conducted on various IoT-based processors. In an 8-bit AVR environment, LIGHT version of Fast AES CTR-mode Encryption (FACE-LIGHT) was proposed at ICISC'2019 conference. However, in a Wireless Sensor Network environment, where sessions are frequently changed, FACE-LIGHT seems not efficient in terms of available memory and generating a pre-computation table. In this article, we present a new column-wise fashion implementation. Unlike previous best AES implementations, our proposed implementation in an 8-bit AVR microcontroller combines SubBytes, ShiftRows, and MixColums operations and optimizes the operation speed through efficient register scheduling. Our constant-time implementation uses a significantly less table than FACE-LIGHT in an 8-bit AVR microcontroller, achieving 2,251, 2,706, and 3,160 clock cycles when encrypting 128-bit data for each of three security levels. In particular, our 256-bit security level AES implementation is the fastest AES implementation as far as we know in 8-bit AVR microcontroller. Finally, we apply our implementation in CounTeR-mode_Deterministic Random Bit Generator (CTR_DRBG), one of the upper algorithms of a symmetric-key algorithm, to prove the generality of our optimization technology in various operating modes of AES.

Abstract

Using microcontroller systems becomes a routine in various measurement and control tasks. Their wide availability together with a huge potential of extending their functionality by additional modules allows developing advanced measuring and monitoring systems by non-specialists. However, using popular example codes often leads the user to pass over or not to be aware of the limitations of the system and drawing too farreaching conclusions on the basis of incorrectly performed measurements This paper deals with the problem of choosing the right method for performing measurements using an acquisition system based on the budget Arduino UNO solution. The main assumption was to use the standard, widely available Arduino libraries. The work focuses on the scenario when data should be subject to time and frequency analysis in the later processing. The operating limits of the device were also determined depending on the data transmission method used. [ABSTRACT FROM AUTHOR]

Abstract

Most of Safes lock system is still using conventional methods nowadays. The conventional method leads to the safes’ burglary. Some of the causes are the safes’ code that can be tracked easily and the key can be duplicated. Previous research on safes’ security has ever been done. The weakness of the study is there is no security system using cryptographic algorithms for data security. The development of a safes security system by implementing ElGamal algorithms is done by following the engineering approach with the stages of methods analysis and design system, implementation and testing of the analysis and the discussion of the overall system. In the analysis and design of mathematical models using ElGamal algorithms, uses fast powering theorems and applications design uses Object Oriented Programming. In the analysis of hardware refers to the datasheet and calculation of the value of electrical characteristics of the circuit. In the safes lock system, the outcome of the research is a safes prototype which is equipped with enhancements that include a series of processing algorithms, the data viewer, a wireless data transfer device, the Android smartphone as a system of user authorization. For the lock safes systems is using a locked solenoid. The control system is done by a lock safes android smartphone via Bluetooth communication. The test results also indicate the system will open the safes if the code and the public key is entered correctly, and the system will not open if one of the codes or the public-keys are wrong or both are wrong.

25. Multiprecision multiplication on AVR revisited.

Author

Hutter, Michael and Schwabe, Peter

Abstract

This paper presents new speed records for multiprecision multiplication on the AVR ATmega family of 8-bit microcontrollers. For example, our software takes only 1,969 cycles for the multiplication of two 160-bit integers; this is more than 15 % faster than that demonstrated in previous work. For 256-bit inputs, our software is not only the first to break through the 6,000-cycle barrier; with only 4,771 cycles it also breaks through the 5,000-cycle barrier and is more than 21 % faster than previous work. We achieve these speed records by carefully optimizing the Karatsuba multiplication technique for AVR ATmega. One might expect that subquadratic-complexity Karatsuba multiplication is only faster than algorithms with quadratic complexity for large inputs. This paper shows that it is in fact faster than fully unrolled product-scanning multiplication already for surprisingly small inputs, starting at 48 bits. Our results thus make Karatsuba multiplication the method of choice for high-performance implementations of elliptic-curve cryptography on AVR ATmega microcontrollers. [ABSTRACT FROM AUTHOR]

Abstract

As the world population grows, energy consumption is increasing, widening is the power deficiency. This creates more demand for energy efficient devices in the market. The lighting systems that are widely being used now do not employ any control energy utilization. In this paper we present wireless embedded control that can be used for both indoor lighting as well as outdoor lighting to switch on/off the lights and as well to reduce the light intensity of LED light which can reduce the power consumption effectively. This improves energy efficiency of the lighting system as well as provides a sophisticated control over the energy consumption of the system. [ABSTRACT FROM PUBLISHER]

Abstract

The door is an essential part of any structure that provides access and security of lives and properties. The manual operation of a door could be cumbersome and laborious when the traffic volume is high. Also, it has been observed that doors could serve as a medium of spreading the deadly coronavirus disease 2019 (COVID-19) infection. Therefore, a prototype automatic sliding door that plays a crucial role in curbing the spread of this infectious diseases has been designed and implemented in this paper. The design of the prototype sliding door is in two parts namely; the structural part and the automation part. The structural design of the door was achieved using the Microsoft Visio 2016 while the design of the automation system was achieved using express printed circuit board. The implementation of the structural part was achieved using 1 inch particle board while the implementation of the automation system was based on the components like the active infrared sensor, resistors (10 kΩ), capacitor (1000 µF), transistors (TIP41 Q8, BC548 Q7), LED indicators, press button switch, pulley system, drive belt, stepper motor (IP65), and ATMEGA 8 microcontroller. The result of the tests carried out on the door showed that the prototype automatic sliding door was characterized by average opening time, closing time, delay time, and optimal sensing range of 3.10 s, 3.05 s, 5.72 s, and 23.5 cm, respectively. It can therefore be concluded from this work that the prototype automatic sliding door is effective in overriding the manual operation of the door.

Abstract

Sustav dodjele prioriteta pametne utičnice je sustav u kojemu mikroupravljač Atmel ATmega16 upravlja relejnim modulom za otvaranje ili zatvaranje izmjeničnog strujnog kruga ovisno o varijablama unešenim od strane korisnika. Mikrokontroler moţe raditi u jezgrenom načinu rada pri kojem korisnik upravlja sustavom pomoći tipki direktno spojenim na mikrokontroler i u mobilnom načinu rada gdje korisnik moţe upravljati sustavom svojim mobilnim ureĎajem koristeći Bluetooth tehnologiju. Dodjela prioriteta zamišljena je na način da korisnik koji prvi odabere ţeljeni termin i relejnu jedinicu ima prioritet nad tom jedinicom u tom terminu. Ţeli li se drugi korisnik prijaviti u tom terminu, sustav odašilje poruku na mobilni ureĎaj korisnika da je termin prethodno zauzet i ispisuje ime korisnika koji ga je zauzeo. Smartplug priority assignment system is designed as a device in which microcontroller Atmel ATmega16 controls a relay module for opening and closing alternating current circuits depending on the commands entered by multiple users. The microcontroller has 2 modes of operation. The first mode, called „Core Mode“, allows the user to enter the commands using pushbuttons near the microcontroller. The second mode of operation, called „Mobile mode“, allows the user to enter the commands by using a personal mobile device via Bluetooth technology. Priority allocation means that the first user who enters his opening period and chooses a relay number gets priority during that period for that relay. If any other user tries to connect during that period, the system will send a message to his mobile device via Bluetooth that says that that period is already occupied and it will display the name of the user that has priority during that period.
