Abstract Elliptic Curve Cryptography (ECC) is one of the strongest and most efficient cryptographic techniques in modern cryptography. This paper gives the following introduction: The introduction of cryptography’s development; the introduction of the elliptic curve; the principle of ECC; the horizontal comparison between ECC and other types of cryptography; the modern breakthrough of ECC; the applications of ECC; by using a method of literature review. The study’s findings indicate that this factor is responsible for the rapid historical development of cryptography, from the classical password to the leap to modern cryptography. Elliptic Curve Cryptography (ECC), as one of the most important modern cryptographies, is stronger than most other cryptographies both in terms of security and strength, because it uses an elliptic curve to construct and, at the same time, uses mathematical operations to encrypt and generate keys. At the same time, elliptic curve cryptography can continue to improve the speed and intensity with the improvement of accelerators, scalar multiplication, and the speed of order operation. The applications of the elliptic curve in ECDSA and SM2 are very efficient, which further illustrates the importance of elliptic curve cryptography.

Black box cryptography is a cryptographic scheme based on a hardware encryption device, operating under the assumption that the device and the user can be trusted. However, with the increasing use of cryptographic algorithms on unreliable open platforms, the threats to black box cryptography systems have become even more significant. As a consequence, white box cryptography have been proposed to securely operate cryptographic algorithms on open platforms by hiding encryption keys during the encryption process, making it difficult for attackers to extract the keys. However, unlike traditional cryptography, white box-based encryption lacks established specifications, making it challenging to verify its structural security. To promote the safer utilization of white box cryptography, CHES organizes The WhibOx Contest periodically, which conducts safety analyses of various white box cryptographic techniques. Among these, the Differential Computation Analysis (DCA) attack proposed by Bos in 2016 is widely utilized in safety analyses and represents a powerful attack technique against robust white box block ciphers. Therefore, this paper analyzes the research trends in white box block ciphers and provides a summary of DCA attacks and relevant countermeasures, adhering to the format of a research paper..

Cryptography is the science used to protect information from unauthorized access. One promising cryptographic algorithm is the McEliece algorithm, which uses code-based cryptography. This algorithm was introduced by Robert McEliece in 1978 and is known for its resistance to attacks from quantum computers, which are expected to be able to break most current cryptographic algorithms. The McEliece algorithm uses binary Goppa code for encryption and decryption, offering high execution speed and resistance to various types of attacks. Although one of its main drawbacks is the large public key size, recent developments in research have shown progress in reducing the key size without sacrificing security. This study aims to explore the working mechanism of the McEliece algorithm, analyze its advantages and disadvantages, and discuss its potential applications in modern technology. The results of this study indicate that the McEliece algorithm has great potential in the field of quantum-safe cryptography, with applications ranging from secret communication to secure data storage.

Data encryption is made possible via DNA sequences. In this paper, two cases utilizing different DNA properties were studied by combining the DNA codes with those conventional cryptography algorithms. The first case concerned on symmetric cryptography that involved DNA coding with OTP (one time pad) algorithms. Asymmetric cryptography was considered in the second case by incorporating the DNA codes in RSA algorithm. The efficiencies of DNA coding in OTP, RSA, and other algorithms were given. As observed, the computational time of RSA algorithm combined with DNA coding was longer. In order to alleviate this problem, data redundancy was reduced by activating the GZIP compressed algorithm. The present experimental results showed that DNA symmetric cryptography worked quite well in both time and size analyses. Nevertheless, it was less efficient than the compressed DNA asymmetric cryptography.

<em>Quantum Cryptography has emerged as a revolutionary approach to network security, leveraging the principles of quantum mechanics to provide unprecedented levels of protection against contemporary and future threats. This paper explores the landscape of quantum cryptography, emphasizing its importance in addressing the dynamic challenges of network security. It outlines four research objectives aimed at investigating various aspects of quantum cryptography and their implications for network security. These objectives encompass exploring advancements in quantum cryptographic protocols, examining practical implementation challenges, assessing threats posed by quantum computers, and evaluating broader implications for security policies and governance frameworks. Through a comparative research design spanning four countries—UK, USA, Indonesia, and Bangladesh—this study collects data on quantum cryptography protocols, implementation challenges, adoption of quantum-resistant cryptography, and governance frameworks. The findings reveal distinct trajectories in the adoption of quantum cryptographic technologies and governance frameworks across these nations. For instance, the adoption rate of quantum cryptography protocols in the USA started at 32.00% in 2010 and decreased to 11.00% by 2023, indicating a gradual decline. Conversely, Bangladesh saw a significant leap in the adoption rate of quantum-resistant cryptography, soaring from 5.00% in 2010 to 80.00% in 2020, reflecting a robust response to emerging threats posed by quantum computing. Despite promising advancements, integrating quantum cryptography into existing networks presents practical challenges, necessitating careful consideration of scalability, compatibility, and performance. Moreover, the emergence of quantum computers underscores the importance of adopting quantum-resistant cryptographic techniques to mitigate potential risks.

<em>Artificial Intelligence (AI) is transforming cryptographic approaches to encryption techniques, automating key generation, and strengthening safety mechanisms against cyber threats. Possible applications include strengthening data protection, detecting vulnerabilities, and optimizing cryptographic protocols. In particular, AI-based cryptographic models enhance the non- disable for security systems against advanced assaults, including those posed by quantum computing. Cryptography leverages AI through machine learning algorithms for anomaly detection, AI-based key management, and neural network-based encryption techniques. Basically, these advancements allow for adaptive security frameworks that can recognize and take action against potential breaches in real time. AI-assisted cryptanalysis can also be used to assess the strength of encryption, therefore restructuring cryptographic practices. Legal protection for AI-driven cryptographic solutions under intellectual property laws, particularly the Patents Act, will remain a crucial area of concern as they continue to evolve. Patentability in cryptography has faced challenges because it relies on mathematical algorithms, which are often not considered patentable in many jurisdictions. However, when technical applications, such as higher efficiency or enhanced security, can be demonstrated by AI-based cryptographic methods, they may find a place under the patent-protectable framework. Novelty, inventive step, and industrial applicability are three of the criteria AI innovations in cryptography must satisfy under the laws of patents, which include the Indian Patents Act, 1970, and European Patent Convention (EPC). The patent framework for cryptography is now developing, with courts and regulatory authorities analyzing the degree of protection that should be accorded to cryptographic mechanisms arising from AI. The paper analyses how AI and cryptography intersect regarding patentability in AI-powered cryptographic systems and the challenges posed by the existing intellectual property frameworks.</em>

ABSTRACT Modern cryptography targeted towards providing data confidentiality still pose some limitations. The security of public-key cryptography is based on unproven assumptions associated with the hardness /complicatedness of certain mathematical problems. However, public-key cryptography is not unconditionally secure: there is no proof that the problems on which it is based are intractable or even that their complexity is not polynomial. Therefore, public-key cryptography is not immune to unexpectedly strong computational power or better cryptanalysis techniques. The strength of modern cryptography is being weakened and with advances of big data, could gradually be suppressed. Moreover, most of the currently used public-key cryptographic schemes could be cracked in polynomial time with a quantum computer. This paper presents a renewed focus in fortifying the confidentiality of big data by proposing a quantum-cryptographic protocol. A framework was constructed for realizing the protocol, considering some characteristics of big data and conceptualized using defined propositions and theorems.
