  • A novel multiphase encryption strategy with Fibonacci numbers and matrices
    Triveni Domada, S. Ashok Kumar, Gudela Ashok, D. Chaya Kumari
    Journal of Discrete Mathematical Sciences and Cryptography, 2025
    This paper proposes multiple encryption methods that secures plaintext by integrating various techniques, including the application of graph theory to trees, Fibonacci matrices, and affine transformations. The use of multiple encryption layers minimizes the risks associated with data encryption by ensuring that the compromise of a single layer does not jeopardize the overall security. This multiencryption method can be extended to public key cryptosystems. We introduce a super encryption technique that employs Laplace transformations and Fibonacci numbers. The process begins by applying the Laplace transformation to a selected function, followed by the incorporation of Fibonacci numbers to super encrypt the plaintext. Decryption is achieved by applying the inverse Laplace transform along with the corresponding Fibonacci numbers.
  • Super-encryption technique of graphs via matricial approach
    Triveni Domada, Gudela Ashok, S. Ashok Kumar, D. Chaya Kumari
    Journal of Discrete Mathematical Sciences and Cryptography, 2024
    Graph theory is quickly becoming an important area of research due to its numerous applications in areas like cryptography, coding theory, communication networks and their security. In this paper a super-encryption method of graphs is proposed via matricial approach for maintaining confidentiality in communicating the messages with two layers of encryption by taking the first level of encryption as the incidence matrix. The message is further encrypted using Fibonacci numbers (taken in matrix form) by adding to the corresponding elements of the product of the incidence matrix of the graph and message (taken as diagonal matrix). Here the graph can be taken as private key. The matrix so formed can be treated as an adjacency matrix which in turn can be represented as a graph and will be sent to the receiver as super encrypted message. The receiver writes the adjacency matrix corresponding to the graph, then subtracts the Fibonacci matrix from adjacency matrix and then multiplies it with the inverse of incidence matrix. Finally, receiver decrypts the message using the private key shared.
  • A new frontier in information security: Polynomial-Fibonacci hybrid cryptography
    Gudela Ashok, S. Ashok Kumar, D. Chaya Kumari, K. V. M. Vara Kumar, Mathe Ramakrishna
    Journal of Discrete Mathematical Sciences and Cryptography, 2024
    This research paper presents an innovative approach to fortify cryptographic systems by integrating Fibonacci polynomials into network security protocols. Leveraging the unique characteristics of polynomials and Fibonacci sequences, our methodology establishes public and private keys, enhancing message transmission security. Initial encryption with polynomials is followed by incorporating Fibonacci polynomials for an added layer of protection. Through this study, we demonstrate how Fibonacci techniques can enhance system security, providing advanced safeguards for network communications. By integrating polynomials and Fibonacci methods, our approach strengthens defense against potential threats, elevating overall system security. This innovative Polynomial-Fibonacci Hybrid Cryptography offers a promising avenue for enhancing data security in contemporary communication systems amidst escalating digital challenges.
  • A type of public cryptosystem using polynomials and pell sequences
    Gudela Ashok, S. Ashok Kumar, D. Chaya Kumari, Mathe Ramakrishna
    Journal of Discrete Mathematical Sciences and Cryptography, 2022
    In this paper, a kind of Public key Cryptosystem is established using Polynomials and Pell sequences by exploiting the properties of both Polynomials and Pell sequences by converting Polynomial into Octal and Binary system. Securing the digital data and modifying it by using modern Cryptographic methods that plays a vital role in Network Security.
  • A secure Diffie-Hellman encryption scheme over elliptic curves using golden matrices
    R. Kumar Bora, S. Ashok Kumar, L. Kishore Kumar, N. Surendra
    Advances in Mathematics Scientific Journal, 2020
    A BSTRACT . In this paper, we proposed a secured Diffie-Hellman encryption scheme over the elliptic curves based on golden matrices. This algorithm works with a bijective function defined from the points on the elliptic curve to ASCII characters. The additional private key has been generated by the matrix, obtained from golden matrices.
