Introduction

The rapid development of technology has brought about numerous benefits, including the ease of data exchange. However, this convenience also poses new challenges related to information security. Digital data, particularly images, is highly vulnerable to abuse, especially those related to copyright. Digital images are often used to store logos, artwork, and other valuable information, making it essential to protect this data from unauthorized parties. One of the solutions that can be relied upon to maintain image security is cryptography. However, security methods that use a single key are considered less secure. To improve security, super encryption techniques are an attractive choice.

What is Super Encryption?

Super encryption is a technique that combines two or more cryptographic algorithms to secure data more effectively. This approach is designed to provide stronger protection against important data, such as digital images, which are often the target of abuse. By utilizing the advantages of each algorithm, the system that is built is not only safer but also efficient in the use of storage space.

Algorithm Analysis

Hill Cipher

Hill Cipher is a cryptographic algorithm that uses a matrix to convert text into an unreadable form. The advantage of Hill Cipher is its ability to encrypt a number of characters at once, thus speeding up the encryption process. However, the weakness lies in the key size that must be square, which can sometimes be a limit in its use.

Key Features of Hill Cipher:

Matrix-based encryption: Hill Cipher uses a matrix to convert text into an unreadable form.
Speedy encryption: Hill Cipher can encrypt a number of characters at once, making it a faster encryption method.
Limitations in key size: The key size must be square, which can sometimes be a limit in its use.

Vigenere Cipher

Vigenere cipher is a simpler but effective encryption method, which uses keys to shift characters in text. The advantage of Vigenere is its simplicity and the ability to strengthen security despite using shorter keys. However, frequency attacks can be a threat if the key is not strong enough.

Key Features of Vigenere Cipher:

Simple encryption method: Vigenere cipher is a simpler encryption method that uses keys to shift characters in text.
Strengthened security: Vigenere cipher can strengthen security despite using shorter keys.
Vulnerability to frequency attacks: Vigenere cipher can be vulnerable to frequency attacks if the key is not strong enough.

Beaufort Cipher

Beaufort Cipher is a variation of Vigenere Cipher that uses a different approach in the encryption and decryption process. The uniqueness of this algorithm is its ability to change the encryption function so as to produce different results even with the same key. This provides an additional level of security that is needed in the super encryption scheme.

Key Features of Beaufort Cipher:

Variation of Vigenere Cipher: Beaufort Cipher is a variation of Vigenere Cipher that uses a different approach in the encryption and decryption process.
Ability to change encryption function: Beaufort Cipher can change the encryption function to produce different results even with the same key.
Additional level of security: Beaufort Cipher provides an additional level of security that is needed in the super encryption scheme.

Application in Image Encryption

The application of super encryption techniques in this study shows promising results. The image file produced after the encryption process has a smaller size compared to the original image file. This shows that the compression process can also be done in conjunction with encryption, thus optimizing the use of storage space.

Benefits of Super Encryption in Image Encryption:

Smaller image file size: The image file produced after the encryption process has a smaller size compared to the original image file.
Optimized storage space: The compression process can be done in conjunction with encryption, thus optimizing the use of storage space.
Improved security: Super encryption provides an additional level of security that is needed in the image encryption process.
