    Study Notes

    Introduction to DNA Cryptography

    • DNA cryptography is a rapidly developing field using deoxyribonucleic acid (DNA) to encode and transmit information.
    • It leverages DNA's highly complex and stable structure for secure data storage.
    • The technology uses DNA's inherent characteristics to create a robust and secure storage system.
    • Research focuses on DNA's potential for secure data encryption.

    DNA Structure and Properties

    • DNA is a double-helix structure made up of nucleotides (adenine, guanine, cytosine, and thymine).
    • The specific order of these nucleotides creates the genetic code.
    • DNA has high stability and can be stored for long periods.
    • DNA synthesis allows information duplication and replication.
    • DNA is easily manipulated using biotechnology techniques, making it a potential tool for data storage.

    Encoding Information in DNA

    • Information is converted into a sequence of DNA bases (A, T, G, C) representing binary digits (0, 1).
    • Various encoding schemes convert digital data into DNA sequences.
    • Encoding information into DNA precisely requires precise biological synthesis of the DNA strands.
    • Sophisticated algorithms for efficient DNA encoding are essential for practical applications.

    DNA Synthesis and Amplification
