“…Texts with pictures, sounds, and animations will be interesting point for primary students to create effective learning. The presence of pictures, sounds, and animations is no longer impossible in digital era, considering the development of technology [46]. It is able to help teacher in producing media or teaching material which is appropriate with primary students' characters that are easily bored and more interested in new things [47].…”

Android based teaching material can facilitate students and teacher in the inside and outside classroom learning using smartphone. This study aims to investigate the ways in utilizing construct 2 apps to create android based material to teach early reading for primary students. This study is qualitative research in form of explorative case study which includes students in private and public primary schools at five regencies of Indonesia. The research data is collected using questionnaire and interview. It is analyzed using content analysis. The results of study show that android based material of early reading can be created by utilizing three steps. The conclusion of this study is that android based material of early reading is firstly created by investigating the need of material for primary students. Secondly, it creates the concepts of materials by preparing the material compositions, creating material order, and creating teaching material tools. Thirdly, construct 2 apps is utilized to make the teaching materials based on the concepts by creating parts of learning guide, invitation for praying, materials, evaluation, and games.

“…Therefore, there are more converter stations built in China. Under the same power conversion conditions, the cost of UAV converter station is lower, and the line loss is smaller [4][5][6] , which is more suitable for China's power supply and distribution environment. However, in recent years, the internal equipment arrangement of UAV converter station in China has become more and more dense, and the composition complexity has become higher and higher.…”

Conventional encryption and return method of UAV converter station inspection image mainly uses Fibonacci scrambling technology to generate two-dimensional encryption mapping, which is easily affected by pixel iteration, resulting in a high difference in peak signal-to-noise ratio. Therefore, a new encryption and return method of UAV converter station inspection image is needed, and an encryption and return algorithm of UAV converter station inspection image is designed based on chaotic sequence. The experimental results show that the difference between the peak signal-to-noise ratio (PSNR) before and after the encrypted return of the inspection encrypted image of the UAV converter station is small, which proves that the encrypted return of the inspection encrypted image is effective, reliable and has certain application value, and has made certain contributions to improving the inspection effect of the UAV converter station.

“…However, this analysis did not extend to security implications. Distinct cryptographic strategies using face anti-magic labelling were unveiled by Kuppan et al [17], while Rao et al [18] advanced a novel image encryption approach through visual cryptography, leveraging the Least Significant Bit (LSB) technique in the spatial domain. In another study, Rama et al [19] augmented the use of CA for DES key generation, primarily benefitting from the randomness induced by CA rule 30, although a limitation was observed in the reduced key size.…”

Cryptosystems worldwide employ techniques for the encryption and decryption of sensitive data, relying extensively on secret keys. In this context, the generation of a randomized, secured secret key and its size hold paramount significance in ensuring confidentiality, data integrity, and resistance to a plethora of security attacks, rendering it arduous for potential intruders to predict key sequences. This study aims to generate the highly secured randomized secret key, minimize the time complexity and ensure efficiency of the cryptosystem. In the key generation methodology presented, a novel approach was introduced, taking into account the receiver's credentials and employing the elementary cellular automata (CA). Rule 150 of CA was strategically leveraged to generate a secret key, undergoing numerous iterations to bolster security, intricacy, and to compound the predictability challenge of the key. Python was the chosen medium for the implementation of the proposed model. Time complexity was rigorously evaluated, and a comparative analysis was conducted against established cryptographic algorithms, notably Rivest-Shamir-Adleman (RSA) and Advanced Encryption Standard (AES), to ascertain efficiency. Subsequently, a frequency analysis, underpinned by a letter frequency distribution chart, was undertaken to confirm the randomness of the resultant ciphertext (CT). To further validate the robustness of the proposed model, security assessments encompassing brute force attacks, CT attacks, known plaintext (PT) attacks, and chosen PT attacks were meticulously examined. Cumulative findings corroborate the heightened security and efficiency of the proposed model in contrast to its predecessors. Anticipated future research horizons include the potential incorporation of CA in domains such as image and video encryption, blockchain technology, cryptocurrency, and digital signatures, aiming to cultivate superior security infrastructures.
