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.

Security of the data is of utmost importance, whenever the data flows on the network. In the current times and t[i]mes to come, cyber security is going to occupy the center stage in the lifecycle of any software. Security is an evergreen and everlasting area, because of the continuous threat from Hackers and Crackers. The proposed work focuses on the protection of the data in the area of Social Network. It has been achieved by the design and development of a new encryption technique called as PentaPlicative Cipher Technique. The PentaPlicative Cipher Technique makes use of multiple keys such as Latitude, Longitude, IP Address and MAC Address of node et al. to securely encrypt the message that needs to be transmitted through a non-secure channel. The paper concludes with an effective comparison in terms of space and time Complexity between Triplicative and PentaPlicative Cipher Technique. [ABSTRACT FROM AUTHOR]

Cryptography system gives security services ability to protect information from people who are authorized to use it. This research introduces elevated information security system via hybrid of new expand Rivest Shamir Adleman (RSA) and data encryption standard (DES) cryptosystem using appropriate standard lgorithms. An Expand Algorithm (ERSA) algorithm Key cryptosystem based on nth large prime number system was introduced. Then a hybrid between the Expand Algorithm (ERSA) with Data Encryption Standard (DES) was applied using four randomly selected variables, each generated from large factor of "N" prime numbers. The information undergoes a cypher text-decryption process which provides strong security and uphold high information confidentiality and integrity of data. Results showed that the use of ERSA and DES algorithm reduced the key generation period and its complexity analysis of encryption and decryption are stronger, unlike the application of traditional RSA algorithm.

Plain text information hiding is vulnerable to active attacks such as deletion and change,which makes the embedded secret information damaged.Blockchain is characterized by non-tampering,non-forgery,anonymity and node information synchronization,making it a natural platform for building hidden channels and ensuring that secret information is not destroyed.This paper proposes the blockchain covert communication model for plain text information hiding.Firstly,the location of the embedded secret information is determined according to the partial order relation.The sender uses the space method to embed the secret information into the plain text content.Then,a scenario of hidden communication in the blockchain network is constructed,and the sender publishes the transaction containing the plain text content to the blockchain network.Finally,after the transaction is packaged and a chain block is formed,any node can obtain the file as the receiver,but only the trusted party can extract the secret information through the inverse process of the embedded algorithm.Experimental comparison and analysis show that the model has better anti-detection,robustness,security and higher hiding capacity.More importantly,the blockchain as a channel enables the identity of the trusted party to be hidden,and the concealment of the communication process is doubly guaranteed.

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]

Plain text data consists of a sequence of encoded characters or “code points” from a given standard such as the Unicode Standard. Some of the most common file formats for digital data used in eScience (CSV, XML, and JSON, for example) are built atop plain text standards. Plain text representations of digital data are often preferred because plain text formats are relatively stable, and they facilitate reuse and interoperability. Despite its ubiquity, plain text is not as plain as it may seem. The set of standards used in modern text encoding (principally, the Unicode Character Set and the related encoding format, UTF-8) have complex architectures when compared to historical standards like ASCII. Further, while the Unicode standard has gained in prominence, text encoding problems are not uncommon in research data curation. This primer provides conceptual foundations for modern text encoding and guidance for common curation and preservation actions related to textual data.
