      <abstract>
        <p>This study investigated a novel cryptographic approach involving the encryption of plaintext using the coefficients of a Taylor series for the logarithm function multiplied by its corresponding index. The decryption process utilized the Laplace transform of the logarithm function and its inverse. Through this methodology, several innovative mathematical encryptions and decryption formulas were derived. The study also includes a practical example to demonstrate the broader implications of the findings.</p>
