Hybrid Cryptosystem RSA and Hill Cipher Algorithm with Fingerprint Lock: A Comprehensive Analysis

In today's digital age, information security has become a top priority. With the increasing reliance on digital communication, the need to protect sensitive information has never been more pressing. One effective way to safeguard data is through the use of cryptographic systems. This article delves into the analysis of a hybrid cryptographic system that combines the RSA algorithm, an asymmetrical key system, with the Hill Cipher, a symmetrical key system. The integration of fingerprints as an encryption key adds an extra layer of security, making it an attractive solution for protecting sensitive information.

Understanding Cryptographic Hybrid Algorithms

A hybrid cryptographic system is a combination of two or more cryptographic algorithms, each with its unique characteristics and strengths. In this study, we focus on the integration of RSA and Hill Cipher algorithms. RSA is an asymmetrical key system, where a pair of keys is used for encryption and decryption. The public key is used for encryption, while the private key is used for decryption. On the other hand, the Hill Cipher is a symmetrical key system, where the same key is used for both encryption and decryption.

The Role of Fingerprints in Cryptographic Systems

Fingerprints have been widely used as a biometric authentication method. In this study, we explore the use of fingerprints as an encryption key in a hybrid cryptographic system. By using fingerprints as a key, the actual key used for encryption is hidden, making it more difficult for unauthorized individuals to access the encrypted data. This adds an extra layer of security to the system, making it more resistant to attacks.

The Benefits of a Hybrid Cryptographic System

A hybrid cryptographic system that combines RSA and Hill Cipher algorithms with the use of fingerprints as a key offers several benefits. Firstly, it provides an additional layer of security, making it more difficult for unauthorized individuals to access the encrypted data. Secondly, it ensures that the key used for encryption is different from the key used for decryption, making it more resistant to attacks. Finally, it provides a fast and efficient encryption and decryption process, making it an attractive solution for protecting sensitive information.

Message Security and Integrity

One of the key findings of this study is that the security of messages increases significantly using a hybrid cryptographic system. The use of fingerprints as an encryption key ensures that the key used for encryption is different from the key used for decryption. This makes it very difficult for those who are not authorized to guess the key used, because the number of characters sent to the recipient is not the same as the actual number of key characters.

Encryption and Decryption Process Time

This study also evaluated the time needed to decrypt ciphertext using the RSA hybrid algorithm and Hill Cipher. Although the time needed to decrypt with this method is longer than using only the Hill Cipher algorithm, the decryption results remain the same. This is because every character encrypted into one ASCII character, so that the file size before and after encryption remains consistent.

The Importance of Modulo 256

One of the key factors in the encryption process is the use of Modulo 256. In this calculation, the character limit after encrypted and decrypted ranges from 0 to 255. This ensures that there is no data loss during the encryption and decryption process, as well as maintaining the integrity of the message sent.

Conclusion

In conclusion, a hybrid cryptographic system that combines RSA and Hill Cipher algorithms with the use of fingerprints as a key offers great potential in increasing message security. Although there is a slight increase in time needed for decryption, the benefits in terms of security and efficiency cannot be ignored. With cryptographic technology that continues to develop, the use of systems like this will be increasingly relevant in protecting information in the increasingly complex digital world.

Future Directions

Future research directions include exploring the use of other biometric authentication methods, such as facial recognition or voice recognition, as an encryption key. Additionally, the development of more efficient and secure cryptographic algorithms is essential to keep pace with the evolving digital landscape.

Recommendations

Based on the findings of this study, we recommend the use of hybrid cryptographic systems that combine RSA and Hill Cipher algorithms with the use of fingerprints as a key. This system offers a high level of security and efficiency, making it an attractive solution for protecting sensitive information.

Limitations

This study has several limitations. Firstly, the use of fingerprints as an encryption key may not be suitable for all applications, particularly those that require high-speed encryption and decryption. Secondly, the use of Modulo 256 may not be suitable for all types of data, particularly those that require a larger character limit.

Conclusion

In conclusion, this study provides a comprehensive analysis of a hybrid cryptographic system that combines RSA and Hill Cipher algorithms with the use of fingerprints as a key. The findings of this study demonstrate the potential of this system in increasing message security and efficiency. We recommend the use of this system for protecting sensitive information and highlight the need for further research in this area.
