**Hybrid Cryptosystem uses Public H-Rabin Key Algorithm and RC6 Cipher Block Algorithm in Data Security**

Introduction

In today's digital age, data security has become a crucial aspect of protecting sensitive information from unauthorized access. With the increasing sophistication of technological developments, threats to data security are also on the rise. Irresponsible parties can reveal confidential information, making data security a top priority. To overcome this problem, a method is needed to protect data or information using message encoding techniques in cryptography. One effective solution is the application of a hybrid cryptographic system, by combining two different algorithms. In this case, the RC6 symmetrical algorithm and H-Rabin asymmetrical algorithms are used simultaneously to secure data.

Understanding the RC6 Algorithm

The RC6 algorithm is a symmetrical algorithm that has several advantages, including the speed of encryption and decryption processes. This process takes place in the same way, without increasing the size of the encryption file. However, one of the weaknesses of the symmetrical algorithm is the need to distribute keys safely. Therefore, asymmetrical algorithms are needed to secure the key distribution. This is where the H-Rabin algorithm plays an important role. H-Rabin is a development of the Rabin algorithm, which has the advantage of producing eight possible cipher, making it more difficult for cryptanalyst to solve.

The Role of H-Rabin Algorithm in Data Security

H-Rabin is an asymmetrical algorithm that uses a different key for each encryption and decryption process, thereby increasing the level of security. Recent research shows that the key length (cipherkey) produced by the H-Rabin algorithm is greater than the key length of the original message (Plainkey). This shows that the longer the key and message used, the longer the time needed for the encryption and decryption process. In terms of complexity, the RC6 algorithm has complexity θ (n) in the encryption and decryption process. Meanwhile, the H-Rabin algorithm also shows the complexity of θ (n) in both processes, assuming that the exponential function of the modulo can be completed in time θ (1).

The Advantages of Hybrid Cryptographic System

The advantage of this hybrid cryptographic system lies in a combination of two supporting algorithms. The symmetrical algorithm provides speed to the encryption and decryption process, while the asymmetrical algorithm provides an additional layer of security in terms of key distribution. By applying this method, the level of data security can be significantly increased, reducing the risk of leakage information that can endanger the confidentiality of data.

The Application of Hybrid Cryptographic Systems

The application of hybrid cryptographic systems using the H-Rabin and RC6 algorithms is not only useful in maintaining data confidentiality, but also as a preventive measure to increasingly complex security threats. By understanding and using this technology, individuals and organizations can increase their defense against attacks that might occur, and protect the important information they have.

Conclusion

In conclusion, the hybrid cryptographic system using the H-Rabin public key algorithm and the RC6 cipher block algorithm is a powerful tool in safeguarding data. By combining the advantages of symmetrical and asymmetrical algorithms, this system provides a high level of security and reduces the risk of data leakage. As technology continues to evolve, the need for advanced data security measures will only increase. By understanding and applying this technology, individuals and organizations can protect their sensitive information and stay ahead of the threats.
