KEY CRYPTANALYSIS H-Rabin Algorithm Using The Kraitchik Method

Introduction to Cryptography and Cryptanalysis

Cryptography is the study of how to protect data to remain safe and confidential from unauthorized parties. In the world of cryptography, there is also a field called cryptanalysis, which is a technique or method used to disassemble or solve the security system of the cryptographic algorithm. Cryptanalysis is a crucial aspect of cryptography as it helps in understanding the strengths and weaknesses of various cryptographic algorithms. In this article, we will discuss the H-Rabin algorithm, a well-known asymmetrical cryptographic algorithm, and its cryptanalysis using the Kraitchik method.

Understanding the H-Rabin Algorithm

The H-Rabin algorithm is a public-key cryptographic algorithm that uses a complicated public key with the formula ${n = p \cdot q \cdot r}$, where ${p}$, ${q}$, and ${r}$ are prime numbers that meet the requirements ${P \equiv Q \equiv R \equiv 3 \, (\text{mod} 4)}$. The safety of the H-Rabin algorithm lies in the difficulty in factoring the value of ${n}$ produced. Therefore, a reliable preparation method is needed to carry out cryptanalysis of this algorithm.

The Kraitchik Method: A Reliable Preparation Method

The Kraitchik method is one of the reliable preparation methods used in cryptanalysis. This method has a complexity that depends on the factors of a number, so it is considered to have good performance in terms of cryptanalysis. The Kraitchik method is a factorization method that can be used to factorize a number into its prime factors. In the context of H-Rabin cryptanalysis, the Kraitchik method is used to factorize the public key ${n}$ into its prime factors ${p}$, ${q}$, and ${r}$.

Challenges in H-Rabin Cryptanalysis Using the Kraitchik Method

However, there are its own challenges in H-Rabin cryptanalysis using the Kraitchik method. H-Rabin requires three prime value secret keys, while the results of the Kraitchik method only produce two numbers. To overcome this, the Kraitchik method process must be done twice. The first process will change the value of ${n}$ (H-Rabin public key) into two excellent factors, which will produce two outputs: ${p}$ (prime number which is the secret key of H-Rabin) and ${x}$ (numbers that are not excellent). After that, the value of ${x}$ will be processed again with the Kraitchik method to get two new values, namely ${Q}$ and ${r}$, both of which are the secret keys of the H-Rabin algorithm.

Solving the Public Key of the H-Rabin Algorithm Using the Kraitchik Method

In this study, the author managed to solve the public key of the H-Rabin algorithm using the Kraitchik method. The results showed that the maximum limit of public keys that can be accessed with this method has a character length of up to 8 digits. This success shows the potential of the Kraitchik method in cryptanalysis, especially for algorithms that have strong mathematical bases such as H-Rabin.

Overall, this study made a significant contribution to the development of cryptanalysis techniques, as well as highlighting the importance of efficient factoring methods in facing security challenges faced by modern cryptographic algorithms. Strong cryptography is very important in maintaining the confidentiality of information in this digital age, and cryptanalysis as discussed can help in the review and improvement of the existing security system.
