Introduction

In the world of cryptography, data security is a top priority. One method that is often used to protect data is encryption. With the increasing amount of sensitive information being transmitted and stored online, it's essential to choose the right encryption method to ensure the security of data. This study discusses the comparison between two famous encryption methods, namely Probabilistic Encryption and Rivest-Shamir-Adleman (RSA). By understanding the strengths and weaknesses of each method, users can make informed decisions when selecting the right algorithm for their specific needs.

Background

Encryption is a process of converting plaintext data into unreadable ciphertext to protect it from unauthorized access. There are various encryption methods available, each with its own strengths and weaknesses. Probabilistic Encryption and RSA are two popular methods that have been widely used in various applications. However, with the advancement of technology and the emergence of new threats, it's essential to evaluate the effectiveness of these methods in providing data security.

The Benefits of the System Built

This study built a supporting system that implemented the algorithm using a programming language. The system utilized the CSPRNG algorithm (cryptographically secure Pseudo Random Number Generator) based on RSA and Rabin-Miller algorithm. The system has significant benefits, including:

Random Key Generation: The system can produce a random key from a predetermined prime number algorithm.
Prime Number Validation: Users can determine the number of the desired prime number, and the system will validate that the number entered by the user is a prime number (non-composite).
Improved Security: The system ensures that the ciphertext produced is safer than potential attacks.

Method Analysis

1. Probabilistic Encryption

Probabilistic Encryption is a method that utilizes elements of uncertainty in the encryption process. This approach makes the system more resistant to statistical analysis attacks. Although the same two messages are encrypted, the results will be different, making it challenging for attackers to analyze the encrypted data. Probabilistic Encryption offers higher security through uncertainty, making it an attractive option for applications that require high levels of security.

2. Rivest-Shamir-Adleman (RSA)

RSA is one of the most popular asymmetrical encryption algorithms. This method uses a key pair, which is a public key for encryption and a private key for decryption. RSA safety depends on the difficulty of large number factors. However, with advances in technology and quantum algorithms, the challenges of RSA security continue to increase. RSA provides convenience in key management, making it a popular choice for applications that require ease of use.

Comparison of Probabilistic Encryption and RSA

Method	Advantages	Disadvantages
Probabilistic Encryption	Higher security through uncertainty, resistant to statistical analysis attacks	More complex to implement, requires advanced mathematical knowledge
RSA	Convenient key management, widely used and accepted	Security challenges increase with advances in technology and quantum algorithms

Conclusion

By comparing these two methods, it appears that each method has its advantages and disadvantages. Probabilistic Encryption offers higher security through uncertainty, while RSA provides convenience in key management. The selection of the right algorithm depends on the specific needs of the application and the desired level of security. Through a system that is built, it is expected to help users in producing safer encryption keys, so that the processed data can be well protected from attacks.

Future Work

This study provides a comprehensive comparison of Probabilistic Encryption and RSA methods. However, there are several areas that require further research, including:

Implementation of Probabilistic Encryption: Developing a more efficient and user-friendly implementation of Probabilistic Encryption.
Quantum Resistance: Evaluating the effectiveness of RSA in resisting quantum attacks and developing new algorithms that are resistant to quantum attacks.
Comparison with Other Methods: Comparing Probabilistic Encryption and RSA with other encryption methods, such as Elliptic Curve Cryptography (ECC) and Advanced Encryption Standard (AES).
