Cryptographs Hybrid One Time Algorithm On and RSA RPrime Algorithm in Securing Text Files

In today's digital age, data and information security is a growing concern. With the rapid advancement of technology, the need for effective data security systems is increasingly urgent. One solution to maintain data security is to use cryptography, a method of converting data into an unreadable form to prevent unauthorized access. Cryptography has two key types: symmetrical and asymmetrical. In this study, we adopted the Hybrid Cryptosystem method that combined the two key types to provide effective solutions in safeguarding text files.

Understanding Cryptography

Cryptography works by converting data into an unreadable form, making it difficult for unauthorized parties to access. The two key types of cryptography are symmetrical and asymmetrical. Symmetrical key cryptography uses only one key for data encryption and decryption, while asymmetrical key cryptography uses two keys: public keys and private keys. The symmetrical key serves to secure data, while the asymmetrical key is used to secure the symmetrical key itself, a process known as a hybrid cryptosystem.

Hybrid Cryptosystem Method

The Hybrid Cryptosystem method combines the advantages of symmetrical and asymmetrical algorithms to provide a secure and efficient data encryption system. The two algorithms used in this study are One Time Pad (OTP) as a symmetrical algorithm and RSA RPrime as an asymmetrical algorithm. The text file that is the object of research is files with *.doc, *.txt, and *.rtf formats. In the testing, the results show that the time needed for file encryption with the *.doc format is longer than other formats. However, the security process using the OTP and RSA RPrime algorithm was successful, as evidenced by the decrypted file size being smaller than the file size when encrypted.

Analysis of the Hybrid Cryptosystem Method

Combining symmetrical and asymmetrical algorithms in one cryptographic system provides its own advantages. One of the advantages of using one time pad is its very high safety, as long as the key used is really random and never used more than once. However, the biggest challenge of OTP is in terms of key storage and distribution, which can be complicated if not managed properly. RSA RPrime, as an asymmetrical algorithm, provides solutions to key distribution problems using public keys that can be distributed freely. However, RSA RPrime tends to be slower in the encryption process compared to symmetrical algorithms.

Advantages of Hybrid Cryptosystem

The application of this cryptosystem hybrid can optimize speed and security. By using the OTP algorithm for data encryption and RSA RPrime to protect symmetrical keys, this system minimizes security risks that may arise due to key management. The hybrid approach not only increases the level of security but also ensures efficiency in data processing. This is because the OTP algorithm provides high safety, while RSA RPrime provides solutions to key distribution problems.

Conclusion

From the results of this study, it can be concluded that the implementation of hybrid cryptography that combines the One Time Pad and RSA RPrime algorithm can provide effective solutions in safeguarding text files. The test shows that although the encryption process in the *.Doc format takes longer, this method is able to secure data with smaller file size results after decryption. Both show that this hybrid approach not only increases the level of security, but also ensures efficiency in data processing. Thus, the use of hybrid cryptography is highly recommended to maintain information security in various file formats in the current digital era.

Recommendations

Based on the results of this study, the following recommendations can be made:

The use of hybrid cryptography should be implemented in various file formats to maintain information security.
