Introduction

In today's digital age, the rapid advancement of technology has made it easier for people to access information and communicate with each other. However, this convenience has also led to an increase in cases of data theft and cybercrime. As a result, the need for secure and reliable systems to protect sensitive information has become more pressing than ever. One way to achieve this is through the use of cryptography, which is a method of protecting information by converting it into a code that can only be deciphered by authorized parties.

Cryptography is a broad field that encompasses various algorithms and techniques, including symmetrical and asymmetrical algorithms. Symmetrical algorithms, such as RC4+, are fast and efficient but offer limited security, while asymmetrical algorithms, such as RSA-CRT, provide better security but are slower and more complex. In this study, we aim to combine the strengths of both types of algorithms to create a hybrid cryptosystem that offers a high level of security and efficiency.

Analysis and Explanation

A hybrid cryptosystem is a combination of two or more cryptographic algorithms that work together to provide a higher level of security and efficiency than a single algorithm. In this study, we propose a hybrid system that combines the RC4+ symmetrical algorithm with the RSA-CRT asymmetrical algorithm. The RC4+ algorithm is used to encrypt the main data due to its ability to process information quickly, while the RSA-CRT algorithm is used to encrypt the symmetrical key used by RC4+.

The use of a hybrid system offers several advantages. Firstly, it provides a high level of security by combining the strengths of both symmetrical and asymmetrical algorithms. Secondly, it offers efficiency by using the RC4+ algorithm to encrypt the main data, which is faster than the RSA-CRT algorithm. Finally, it provides flexibility by allowing the user to choose the level of security and efficiency required for a particular application.

Implementation of Hybrid Cryptosystem

The implementation of the hybrid cryptosystem involves two main stages: encryption and decryption. In the encryption stage, the RC4+ algorithm is used to encrypt the main data, while the RSA-CRT algorithm is used to encrypt the symmetrical key used by RC4+. The encrypted data is then transmitted to the recipient, who uses the RSA-CRT algorithm to decrypt the symmetrical key and the RC4+ algorithm to decrypt the main data.

The decryption process involves two main stages: decryption of the symmetrical key and decryption of the main data. In the first stage, the RSA-CRT algorithm is used to decrypt the symmetrical key, while in the second stage, the RC4+ algorithm is used to decrypt the main data.

Results and Discussion

The results of the study show that the hybrid cryptosystem provides a high level of security and efficiency. The time needed for the encryption and decryption process is relatively fast, making it an efficient choice for safeguarding text files. The results also show that the hybrid system provides a high level of key security, making it a relevant solution to maintain the confidentiality of information.

In conclusion, the implementation of the hybrid cryptosystem RSA-CRT algorithm and RC4+ algorithm in securing text files is a relevant solution to maintain the confidentiality of information. The hybrid system offers a high level of security and efficiency, making it an efficient choice for safeguarding text files. The results of the study show that the hybrid system provides a high level of key security, making it a relevant solution to maintain the confidentiality of information.
