In recent times, there has been a significant surge in research interest in security, driven by the continuous growth of threats and cyber attacks. Recognizing that existing state-of-the-art security schemes may not adequately address the requirements for lightweight properties and enhanced security measures, the aim of this research is to contribute to the field. The focus is on the development and implementation of lightweight encryption protocols designed to bolster security measures in the face of evolving challenges. The primary objective of this endeavor is to create a secure system utilizing the 3-round Kuznyechik algorithm (SSKA). In this process we introduce key generation algorithm followed by encryption and decryption techniques. The key generation algorithm is mainly based on three-round Kuznyechik algorithm. The Kuznyechik 3-round encryption mechanism has been proven to be effective in producing an imbalanced set at the end of the round and a balanced set before to the third round by employing a set in which the first byte is active and the following bytes are passive. This encourage us to use 3-round Kuznyechik algorithm. Building upon the aforementioned findings, an effective algorithm is suggested for determining the key of the final round in the 3-round Kuznyechik algorithm, employing the integral cryptanalysis method. Based on simulation results, the proposed approach demonstrates noteworthy enhancements in comparison to baseline algorithms concerning time complexity, encryption time, throughput, decryption time, data overhead, and space complexity.

In recent years, the Cyber-Physical System (CPS) is ubiquitous and the core of modern critical infrastructure and industrial applications. Moreover, CPS is used for securing digital transactions and records with a high confidentiality rate. The main issues in CPS are harmful, malicious attacks it will break the application security. This paper proposed a novel Elapid Crypto (EC) mechanism for securing CPS from malicious activity. Furthermore, a mapped interface is created in the CPU to access the instruction set of the developed technique. Also, design an elapid core accelerator in the Instruction set for separating data and providing security using private keys. It will convert the plain text into Ciphertext during Encryption. Thus the developed technique is implemented in MATLAB, and the developed EC mechanism encrypts plain text into ciphertext. Additionally, the achieved performance metrics of the proposed EC mechanism are compared with other techniques in terms of execution time, energy, power, number of cycles, and latency.

In this paper, we propose a compression-based encryption technique which is an advanced technique of tight frame encryption and indirect encryption techniques. The proposed approach is applied on ASCII Text code which does compression and at the same time encryption is performed. It divides plain text into blocks of different sizes 9, 10, 11, 12 and 13 bytes. Further, it undergoes rounds where in each round one byte is compressed at the same time and its preceding seven bytes participate in encryption. It takes a block as input and yields resultant block of size seven bytes. The results depict that the proposed approach does more compression and encryption by generating optimal key sizes in experiments carried out in the investigation. Considering implementation issues, the proposed one is a feasible method to implement in all platforms without requiring additional computation and information and does compression and encryption on plain text data simultaneously at great pace.

Hill Cipher is a reimbursement coding system that converts specific textual content codes into numbers and does no longer exchange the location of fixed symbols. The symbol modifications simplest in step with the English letter table inclusive of (26) characters handiest. An encoded Hill Cipher algorithm was used that multiplication the square matrix of the apparent text with a non-public key and then combined it with the Triple Pass Protocol method used to repeat the encryption three times without relying on a personal key. Also, you could decode the code and go back it to the express textual content. The cause of mixing algorithms is to cozy the message without any key change among the sender and the recipient.

The data communication has been growing in present day. Therefore, the data encryption became very essential in secured data transmission and storage and protecting data contents from intruder and unauthorized persons. In this paper, a fast technique for text encryption depending on genetic algorithm is presented. The encryption approach is achieved by the genetic operators Crossover and mutation. The encryption proposal technique based on dividing the plain text characters into pairs, and applying the crossover operation between them, followed by the mutation operation to get the encrypted text. The experimental results show that the proposal provides an important improvement in encryption rate with comparatively high-speed processing. [ABSTRACT FROM AUTHOR]

With the fast increase in airspace density and high‐safety requirements on aviation, automatic dependent surveillance‐broadcast (ADS‐B) is regarded as the primary method in the next generation air traffic surveillance. The ADS‐B data is broadcast with the plain text without sufficient security measures, which results in various attack patterns emerging. However, in terms of constrictions with laws and regulations, ADS‐B attack data is difficult to collect and obtain, which is essential for data security research studies. To deal with the absence of ADS‐B attack data in real environments, the construction strategy on ADS‐B attack data is proposed. For construction fidelity, ADS‐B data features are analysed and modelled at first. Then the popular and classical attack patterns on ADS‐B data are analysed to establish threat models. Based on the original ADS‐B data sets, the construction strategy is designed to focus on attack target selection, key parameter determination, and mixture strategy, reproducing the attack intentions. The constructed ADS‐B attack data sets are hybrid data sets including the normal and attack data. By simulation analyses, the feasibility and availability of the construction strategy were validated with real ADS‐B data. [ABSTRACT FROM AUTHOR]

Automatic detection of encoding and language of the text is part of the Greenstone Digital Library Software (GSDL) for building and distributing digital collections. It is developed by the University of Waikato (New Zealand) in cooperation with UNESCO. The automatic encoding and language detection in Slavic languages is difficult and it sometimes fails. The aim is to detect cases of failure. The automatic detection in the GSDL is based on n-grams method. The most frequent n-grams for Czech are presented. The whole process of automatic detection in the GSDL is described. The input documents to test collections are plain texts encoded in ISO-8859-1, ISO-8859-2 and Windows-1250. We manually evaluated the quality of automatic detection. To the causes of errors belong the improper language model predominance and the incorrect switch to Windows-1250. We carried out further tests on documents that were more complex. [ABSTRACT FROM AUTHOR]

Cryptography is an art of converting information (Plain Text) using encrypting algorithms into a form that cannot be understood (Cipher Text) without access to specific decoding algorithms. The key goal of cryptography is to protect data against unauthorized third-party access by applying encryption and Decryption Techniques. The paper proposes an algorithm which uses a randomized technique in order to encrypt and decrypt information. The proposed algorithm uses techniques of cryptography using various versions of Caesar Cipher and a protocol to implement this algorithm using public key generation and randomized technique (generation of random key) . The algorithm uses actual global time of the sending of message to generate the public key. The algorithm is mainly implemented for Mobile Communication. The paper reviews about the proposed algorithm and implements the algorithm by taking five plain texts (of a text message sent from one mobile to another) an input and calculates the corresponding cipher texts. The paper also determines the number of computations in each of the cases and in proposed randomized technique as well as in individual and compares them in order to obtain effective result. It also highlights the pros and cons of using proposed randomized approach in Mobile cryptography. [ABSTRACT FROM AUTHOR]

This Ρroject measured the effect of using hyΡermedia annotations on short and long-term vocabulary retention in teaching vocabulary through Web-based language learning activities. A total of 62 university students were randomly assigned into two homogeneous grouΡs and then both grouΡs were given a Ρretest. Both grouΡs covered 12 exΡository Ρassages selected by the researchers from the BBC website. The subjects had to sit for an immediate quiz to measure the short-term effect of the treatment and finally, at the end of the course and a two week interval, subjects sat for their Ρost-test. Findings revealed that there was a significant effect of the hyΡermedia annotations on the retention of vocabulary in the short term ( ΡB0.05). However, the Ρost-test results indicated that the effect of the treatment in the long term faded away and the significance of the means was not sufficiently high to reject the null hyΡothesis.
