Implementation of Affine Cipher Combination and Public Locks with Matrices for File Security

In today's digital age, data security has become a top priority for individuals and organizations alike. With the increasing threat of cyber attacks and data breaches, it is essential to have robust encryption methods in place to protect sensitive information. One popular encryption method is the Affine Cipher, which is known for its ease of use. However, its weakness lies in its vulnerability to the Brute Force method, which can easily reveal encrypted messages. To overcome this weakness, a combination with asymmetrical methods such as RSA or El Gamal can be a solution. Although effective, exponential-based asymmetrical methods such as RSA and El Gamal require significant time and memory for the encryption and decryption process because it uses very large exponential numbers (at least 2^1024) for security.

This study explores alternatives by combining Affine Cipher with a public matrix key as an asymmetrical method. This method offers advantages in terms of time efficiency and memory, as well as strong security. In this article, we will delve into the implementation of this method, its advantages, and the research results.

How does this method work?

The combination of Affine Cipher and public matrix key is a novel approach to encryption. The process involves two main steps: encryption and decryption.

Encryption:

The message is first encrypted using the Affine Cipher. The Affine Cipher encryption key is then encrypted using a public matrix key. This public matrix key is used to encrypt the Affine Cipher key, making it difficult for unauthorized parties to access the encrypted message.

Decryption:

The Affine cipher encryption key is decrypted using a private matrix key. After the Affine Cipher key is obtained, the message can be decrypted using the Affine Cipher decryption process.

Advantages of Combination Method:

The combination of Affine Cipher and public matrix key offers several advantages over traditional encryption methods.

Time and memory efficiency:

This method avoids the use of large exponential numbers, so it is more efficient in terms of time and memory. This is particularly important in scenarios where large amounts of data need to be encrypted and decrypted quickly.

Strong security:

Affine cipher combination with a public key matrix offers an additional layer of security that is difficult to penetrate. The use of a public matrix key to encrypt the Affine Cipher key adds an extra layer of complexity, making it harder for unauthorized parties to access the encrypted message.

Ease of implementation:

This method is relatively easy to implement and integrated into a security system. The use of a public matrix key simplifies the encryption process, making it easier to implement and manage.

Research Result:

The results of this study showed that the relationship between process time and plaintext file size was linear. That is, the greater the size of a plain text file, the longer the time needed for the encryption and decryption process. However, changes in the character in the test data show that the combination of Affine Cipher algorithms and public keys with a relatively safe and simple matrix.

Conclusion:

The combination of affine cipher and public keys with the matrix meets the data integrity requirements. This method offers a solution that is efficient, safe, and relatively easy to apply to secure files. In an increasingly complex digital world, this method can be an effective choice to protect sensitive data from unauthorized access.

Suggestion:

Further research can focus on:

Comparing the performance of this method with other asymmetrical methods such as RSA and El Gamal.
Investigate the effect of matrix size on the safety and efficiency of this method.
Apply this method in various practical scenarios, such as medical file protection, financial data, and personal information.
