Implementation of Text Security using the Rabin-P Algorithm and the End of File Algorithm

Introduction

In today's digital era, the exchange of data and information in the form of text messages has become a common practice. However, the security of text messages has become a crucial issue to prevent abuse by unauthorized parties in the transaction process. This study aims to combine the Rabin-P and End of File (EOF) algorithms as a solution to secure text messages.

Understanding the Rabin-P Algorithm

The Rabin-P algorithm is a derivative of the Rabin encryption system, which utilizes a single decryption key in the form of prime numbers to improve data encryption and performance. In its implementation, Rabin-P uses a public key N for encryption and a private key P (prime number) for decryption. This algorithm provides strong cryptographic protection against invalid access, making it an ideal choice for securing sensitive data.

Understanding the End of File (EOF) Algorithm

The EOF algorithm is a steganographic method that hides secret data or messages at the end of the file. This method places the header or data sign at the end of the file, so it does not cause problems in various types of files. The EOF algorithm is a simple yet effective method for hiding text messages in a hidden way.

Combining the Rabin-P and EOF Algorithms

This study results in the conclusion that text messages can be secured by cryptographic methods, then attached to the image file as a closing media using the Steganography method. After that, text messages can be separated from closing media and returned to their original form. The combination of Rabin-P and EOF algorithms offers several advantages in securing text messages:

*** Multiple Security: ** Rabin-P provides strong cryptographic protection against invalid access, while EOF hides text messages in the closing media so it is difficult to detect. ** Efficiency: ** Rabin-P with a single decryption key increases the efficiency and speed of encryption/decryption compared to other asymmetrical cryptographic methods. *** Flexibility: ** EOF can be applied to various types of files, including images, audio, and video, thus allowing the hiding text messages in a hidden way.

Benefits of the Rabin-P and EOF Algorithm Combination

This article provides a deeper understanding of the security technique of text messages by combining the Rabin-P and EOF algorithm. Its application can provide effective solutions to various needs, such as:

*** Financial Transactions: ** securing sensitive transaction data such as account numbers and credit card information. ** Business Communication: ** Protect company internal data and confidential information from invalid access. *** Personal Communication: ** Ensuring personal communication privacy, such as text and email messages.

Implementation of the Rabin-P and EOF Algorithm

To implement the Rabin-P and EOF algorithm, the following steps can be taken:

  1. Generate a public key N and a private key P: The public key N is used for encryption, while the private key P is used for decryption.
  2. Encrypt the text message using the public key N: The text message is encrypted using the public key N to produce a ciphertext.
  3. Hide the ciphertext at the end of the file using the EOF algorithm: The ciphertext is hidden at the end of the file using the EOF algorithm.
  4. Attach the file to an image file as a closing media: The file is attached to an image file as a closing media using the Steganography method.
  5. Separate the text message from the closing media: The text message is separated from the closing media and returned to its original form.

Conclusion

In conclusion, the combination of the Rabin-P and EOF algorithms offers a secure and efficient solution for text message security. The Rabin-P algorithm provides strong cryptographic protection against invalid access, while the EOF algorithm hides text messages in a hidden way. The benefits of this combination include multiple security, efficiency, and flexibility.
