Introduction to DNA Cryptography

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

• DNA synthesis methods, like polymerase chain reaction (PCR), allow for accurate replication and amplification of DNA sequences.
• These processes are crucial for creating and manipulating DNA-encoded data.
• Advanced methods like Solid-Phase Synthesis and automated techniques are key for high throughput and accurate DNA encoding.
• Accurate and efficient DNA strand synthesis is critical for data integrity.

Data Security Aspects

• DNA's inherent stability makes DNA cryptography a potential solution for long-term data storage and secure transmission.
• DNA sequences are difficult to counterfeit or modify.
• Concerns about access to and alteration of DNA data are important.

Current Research Directions
