When it comes to preventing unauthorised access to, destruction of, or inspection of confidential data, information security has always been a major factor. Multimedia information is now used in every field throughout the world. The confidential information that is used in these areas must be kept secure. There are a variety of methods for keeping data secure. One of these is steganography, which is concealing information within other data into a format that the cover information remains unchanged. Cryptography, an encryption process that scrambles data into a written form that is sometimes referred to as a hash, is an auxiliary approach for securing information. Steganography and cryptography each have their own set of benefits and drawbacks. Even though both technologies give security, it is usually a good practise to combine Cryptographic algorithms to create additional layers of security. When cryptographic with steganography are combined, a multi-layer security paradigm is created. The proposed work's main goal is to add an additional layer of protection by using cryptography and steganography to encrypt and embed secret data conveyed across an insecure channel.

Quantum computing has the potential to transforming computational paradigms, posing both a threat and an opportunity to contemporary cryptographic systems and data security frameworks. As quantum algorithms improve, pose a risk to traditional encryption solutions, and the concepts of post-quantum cryptography and quantum-safe security architectures gain momentum, it is of paramount importance that organizations stay ahead of the threat landscape. Keywords— Quantum Computing, Cryptography, Information Systems. This work reviewed the implications of quantum computing in the field of Cryptography and Data Security within Information Systems, analyzing three relevant problems encountered: secure key distribution, computational performance and cryptographic migration; Many works were unable to empirically validate or implement quantum-resistant algorithms in the real world, which represents a significant limitation to existing studies. This work tries to fill this gap by characterizing the security of post-quantum cryptography, including lattice-based, hash-based, and multivariate polynomial cryptosystems, from quantum attacks. Furthermore, we provide a multi-layered security framework that combines quantum-safe encryption, AI-powered anomaly detection, and blockchain-based authentication that would increase resilience against quantum attacks. This research bridges the gap by offering sector-specific insights into quantum security needs across key industries, including finance, healthcare, and government, facilitating the drafting of a standardized security framework and policy recommendations for a quantum-secure future. The research will help organizations and policymakers understand how they can implement scalable quantum-resistant cryptographic solutions and address potential cybersecurity risks associated with the post-quantum world.

Recent breakthroughs in cryptographic technology are being thoroughly scrutinized due to their emphasis on innovative approaches to design, implementation, and attacks. Lightweight cryptography (LWC) is a technological advancement that utilizes a cryptographic algorithm capable of being adjusted to function effectively in various constrained environments. This study provides an in-depth analysis of elliptic curve cryptography (ECC), which is a type of asymmetric cryptographic method known as LWC. This cryptographic approach operates over elliptic curves and has two applications: key exchange and digital signature authentication. Next, we will implement asymmetric cryptographic algorithms and evaluate their efficiency. Elliptic curve elgamal algorithms are implemented for encryption and decryption of data. Elliptic curve Diffie-Hellman key exchange is used for sharing keys. Experimental results have shown that ECC needs small size keys to provide similar security. ECC takes less time in key generation, encryption and decryption of plain text. Time taken by ECC to generate a 2,048 bit long key is 1,653 milliseconds in comparison to 4,258 millisecond taken by Rivest-Shamir-Adleman (RSA) technique.

Cryptography is utilized to make secure data transmission over networks. The algorithm called for cryptography should meet the conditions of authentication, confidentiality, integrity and non-repudiation. Cryptography is a technique used from decenniums to secure and forfend the information and send the data from one place to another without the trepidation of having been read out by some unauthorized and unauthenticated denotes. Several ways has been developed in this field to make the information more secure and evade trespassing. However these methods may have some loopholes or shortcoming which leads to the leakage of information and thus raising a question of information security. The cryptographic technique is utilized not only to provide the security but additionally it deals with data integrity, confidentiality and non-repudiation issues. To safeguard data during transmission or storage, sundry algorithms and methods have been developed in the field of security. A wide range of cryptography approaches are employed, each with its own set of strengths and inhibitions that are acclimated to provide data security. Cryptography can be defined as techniques that cipher data, depending on categorical algorithms that make the data unreadable to the human ocular perceiver unless decrypted by algorithms that are predefined by the sender. It encrypts data utilizing a set of algorithms such as symmetric and asymmetric algorithms. These encryption methods vary in terms of vitality, celerity, and utilization of resources (CPU utilization, recollection, and power). It is utilized to bulwark personal identifiable information (PII) and other confidential data, authenticate identities, avert document tampering, and build trust between servers. Cryptography is one of the most paramount techniques utilized by digital businesses to safeguard the systems that store their most valuable asset – data – whether it is at rest or in kinetic Customer PII, employee PII, perspicacious property, company strategies, and any other confidential information are examples of data. As a result, cryptography is a vital infrastructure, as the aegis of sensitive data increasingly relies on cryptographic solutions. In this paper I have discussed various cryptographic techniques and the inhibitions of those techniques as well.

With the rapid development of the digital age, information security, from personal data to national security, is becoming increasingly crucial. Information security primarily refers to the computation and processing of diverse information in computer systems and information exchange networks in order to safeguard information security. Cryptography is the technical foundation for achieving these objectives. In the early stages of education, advanced mathematics, linear algebra, probability theory, and other fundamental disciplines must be studied, although the practical application of modern algebra, cryptography, number theory, and mathematical knowledge will vary. This study explores the application of current algebra in cryptography, including both traditional and modern cryptographic applications, using a literature review approach. By comparing images from various eras, the researchers discovered that images were classed as "traditional" and "modern" at various times. Moreover, the likelihood of both traditional and modern images being identified throughout the modern era is comparatively higher.

Wireless Sensor Networks are gaining popularity in various fields and areas. But these nodes are vulnerable as they are open networks and easily accessible. The major challenge is to have a secure data transmission between the nodes. To establish a secure transmission, we require a security scheme like a cryptographic algorithm, but this also requires a secure key distribution between nodes. The WSN’s have constraints like limited area, power and memory which restrict all the categories of cryptographic algorithm. Depending upon the criteria’s and constraints, cryptographic algorithm like Elliptic Curve Cryptography ECC is best suitable for WSN’s environment. ECC has a smaller key size, high security and less computation time which makes the node an efficient crypto system. In order to protect the security of data, we propose a novel secure transmission strategy based on Cryptography. In this design, we acquire sensitive information securely so as to make use of the advantage of encryption. Our approach deal with the weakness of limitation in sensor node resources and the security threats, it is suitable for stream data in sensor nodes. The simulation experiments also demonstrate that this approach is effective in transmitting sensitive data covertly with the characteristics of lower energy consumptions and invisibility. This paper describes the implementation of ECC cryptosystem for WSN for secure key and data transmission between the nodes.

Full textAbstract:
Classical cryptographic systems face a hazardous situation because quantum computing operates as a threat vector against classical systems through Shor's and Grover's algorithms. Through Shor's algorithm factoring large integers results in a breach of RSA encryption methods whereas Grover's algorithm enables substantially quicker searches of unsorted databases to diminish symmetric key encryption strength. The advanced features of quantum systems eliminate the foundation of security that classical cryptographic techniques depend on computation complexity for protection. Quantum Key Distribution (QKD) under the principles of quantum mechanics presents an effective solution through quantum cryptography for achieving secure communication. QKD stands apart from classical systems through its complete security because attempts at quantum channel interception automatically disable transmitted information and notifies sender and receiver. The successful deployment of quantum cryptography needs solutions for its high implementation expenses coupled with noise sensitivity along with scalability limitations. The research shows it is vital to actively implement quantum-resistant cryptography now because it will protect sensitive data as the post-quantum computing period begins thus securing global cyberspace infrastructure protection systems. The study demonstrates both promising speed benefits of Hash-Based cryptography but Code-Based cryptography encounters deployment barriers because of its performance restrictions. Future studies must focus on performance development of PQC mechanisms to boost operational speed and sustain security standards.

Security knowledge is one of the foremost challenges in the present day. When the topic is about Information security, the concept of cryptography comes into the picture. Every day, people and organizations use cryptography to maintain the confidentiality of their communications and data as well as to preserve their privacy. Today, one of the most successful methods used by businesses to protect their storage systems, whether at rest or in transit, is cryptography. Yet, cryptography is an effective technique to secure the data, the modern technology can break the cryptographic techniques. But some data encryption algorithms are several times stronger than today's conventional cryptography and can be constructed using quantum computing. They are "Quantum Cryptographic Algorithms ". Quantum cryptography uses the rules of quantum physics instead of classical encryption, which is based on mathematics, to protect and transmit data in a way that cannot be intercepted. Quantum key distribution is the greatest illustration of quantum cryptography and offers a safe solution to the key exchange issue. The proposed work deals with quantum cryptography and mainly focuses on how the quantum cryptographic algorithm is more secure than traditional cryptography.

Cryptography is a key enabling tool in digital security that is needed to protect information, secure communication, and ensure the integrity between connected networks. As cybersecurity threats continue to emerge constantly and, as evidenced by APTs, ransomware, and, later, quantum cyber threats, the need for stronger, more modern generations of cryptographic methods is more urgent than ever. Therefore, this paper seeks to discuss the emerging trends in the most recent cryptographic advancements including post quantum cryptography, homomorphic cryptography and security paradigms leveraging on blockchain system. These techniques are equally effective in correcting significant limitations of existing systems and in improving their overall efficiency and rates. The coursework points out the inherent weaknesses of traditional cryptographic solutions, such as the exposure to quantum computing threat models and their ability to address current and future security needs. Through a brief discussion of the theoretical background and practical implementations, this paper aims to assess the efficiency of the latest cryptographic technologies in strengthening network security measures. Research insights show that using third-generation cryptographic approaches is far more effective in protecting information from new risks. Besides, applying these methods in essential industries, including finance, healthcare, and IoT, supports the practical utilization of these methods. Based on the findings of this research, these innovations should be adopted to secure digital structure in a growing complex environment.

Cryptography is a method of securing data using algorithms that have been developed continuously until now. Cryptography offers security in the form of data confidentiality, for example the confidentiality of data generated through encryption algorithms that scrambles personal information so that it cannot be read or solved by unauthorized parties. One of them is the substitution algorithm and the vigenere cipher is a classic method used for data security. The combination of these algorithm methods becomes a solution for double security as file protection. By using a cryptographic application for data security, the combination of the two method algorithms produces a data file that provides more security to the text file so that it is not easy and difficult to solve.

The article considers the expediency of changing the methods of ensuring information security of automated process control systems (automated process control systems) of extractive industry enterprises. The analysis of foreign experience allowed us to say that the world's leading economies are preparing for the appearance of a cryptographically relevant quantum computer. Many countries have adopted mandatory and recommendatory documents on the transfer of critical information infrastructure to quantum-secure methods of information protection: quantum key distribution or post-quantum cryptography. Both of these methods have their advantages and disadvantages, which must be taken into account when implementing the automated process control system. The analysis shows that post-quantum cryptography, although it requires less economic costs to improve cryptographic information protection systems, but the cryptographic stability of these algorithms is conditionally secure. The study allows us to conclude that it is advisable to recommend quantum key distribution systems for use in the extractive industry...

All the conventional methods of data handling have been replaced by much more sophisticated means. One of the typical shifts of the emerging information society is that information is becoming a crucial if not the most vital source. Information contrasts profoundly from further resources; for example and it can be imitative without cost, it can be erased without leaving traces. [22] Protecting the new resource information is a major issue in the information economy [20]. One such means is a Database. It makes it easier for data related queries butit can be dangerous if this data is leaked or sent outside the organization. A high price is positioned on confidentiality when information concerning statesecrets, business plans, war strategy, medical recordsand financial transactions needs to be stored or transmitted. Since its inception, the Internet has enable [19]. A cyber crime emerging in recent years data breachis one of the most notorious and disastrous data crimes majorly caused due to unsecure database.
