Increases the Security of Document Data with a Combination of RSA and Elgamal Algorithms

In today's digital era, data security has become increasingly important. One way to maintain the confidentiality of data is to use encryption techniques, which is changing data into codes that are not easy to understand without special keys. RSA and Elgamal algorithms are two asymmetrical encryption algorithms that are popular today, both use two keys: public keys and private keys in the encryption and decryption process. The combination of these two algorithms is expected to create a stronger dual security system to protect the confidentiality of the contents of the document file.

Understanding the Basics of RSA and Elgamal Algorithms

RSA and Elgamal algorithms are two of the most widely used encryption algorithms in the world. Both algorithms use a combination of public and private keys to encrypt and decrypt data. The RSA algorithm is known for its ability to maintain the confidentiality of data, while the Elgamal algorithm is well-known for its ability to prevent man-in-the-middle attacks. The combination of these two algorithms is expected to provide a higher level of security than either algorithm alone.

How is the Combination of RSA and Elgamal Increase Security?

The combination of RSA and Elgamal algorithms is a two-stage process. First, the document file is encrypted with the RSA algorithm using the recipient's public key. This process is known as gradual encryption. The results of the RSA encryption are then encrypted again with the Elgamal algorithm using the recipient's public key. This process is also known as gradual encryption. The decryption process is carried out in reverse, first decrypting the document file that has been encrypted with Elgamal using the private recipient key, and then decrypting the results of the Elgamal decryption using the private recipient key used for RSA encryption.

Advantages of RSA and Elgamal Combination Systems

The combination of RSA and Elgamal algorithms provides several advantages, including:

*** Higher Security: The combination of two strong algorithms increases the complexity of the decryption process without the right key, making the data more difficult to access by the unauthorized party. *** Flexible: This system can be applied to various types of document files. *** Easy to Implement: RSA and ELGAMAL algorithms have been widely available in various programming languages, facilitating implementation.

Application in the Real World

The combination of RSA and Elgamal algorithms can be applied to various scenarios, including:

*** Sensitive Data Storage: Important documents such as contracts, financial statements, and medical data can be secured with this system. *** Safe Data Transfer: Document files can be transferred safely between individuals or organizations. *** Data Access Settings: This system can be used to adjust access to document files, only users with private locks can open and access data.

Conclusion

The merging of RSA and Elgamal algorithms provides a more sophisticated and effective security solution to protect data on document files. This system offers a combination of security forces of the two algorithms, providing stronger protection against various attacks. The results of this study are expected to be a step forward in maintaining data security and information in the increasingly complex digital era.

Implementation of the Combination of RSA and Elgamal Algorithms

The implementation of the combination of RSA and Elgamal algorithms involves several steps, including:

Generating Public and Private Keys: The first step is to generate public and private keys for both the RSA and Elgamal algorithms.
Encrypting the Document File: The next step is to encrypt the document file using the RSA algorithm and the recipient's public key.
Encrypting the Results of RSA Encryption: The results of the RSA encryption are then encrypted again using the Elgamal algorithm and the recipient's public key.
Decrypting the Document File: The decryption process is carried out in reverse, first decrypting the document file that has been encrypted with Elgamal using the private recipient key, and then decrypting the results of the Elgamal decryption using the private recipient key used for RSA encryption.

Code Implementation

The code implementation of the combination of RSA and Elgamal algorithms involves several programming languages, including Python and Java. The following is an example of the code implementation in Python:

import rsa

def generate_keys():
    # Generate public and private keys for RSA
    (public_key, private_key) = rsa.newkeys(512)
    return public_key, private_key

def encrypt_document_file(public_key):
    # Encrypt the document file using RSA
    encrypted_document_file = rsa.encrypt("document_file.txt", public_key)
    return encrypted_document_file

def encrypt_results_rsa_encryption(public_key):
    # Encrypt the results of RSA encryption using Elgamal
    encrypted_results = elgamal.encrypt(encrypted_document_file, public_key)
    return encrypted_results

def decrypt_document_file(private_key):
    # Decrypt the document file using Elgamal
    decrypted_document_file = elgamal.decrypt(encrypted_results, private_key)
    return decrypted_document_file

def decrypt_results_elgamal_decryption(private_key):
    # Decrypt the results of Elgamal decryption using RSA
    decrypted_results = rsa.decrypt(decrypted_document_file, private_key)
    return decrypted_results

public_key, private_key = generate_keys()
encrypted_document_file = encrypt_document_file(public_key)
encrypted_results = encrypt_results_rsa_encryption(public_key)
decrypted_document_file = decrypt_document_file(private_key)
decrypted_results = decrypt_results_elgamal_decryption(private_key)
