Penerapan Algoritma Gronsfeld Dengan Pembangkit Kunci Quicksort Untuk Mengamankan Pesan Rahasia

Abstract

The numerous issues often encountered in securing confidential messages revolve around message leaks. Message leaks occur through various means, such as eavesdropping. Eavesdropping happens when unauthorized parties manage to access and obtain information from ongoing communications. One way to maintain the confidentiality of secret messages is through encryption and decryption, known as cryptography, achieved by transforming the original message (plaintext) into a secret message (ciphertext). In this study, the results of the encrypted character ciphertext are v, v, w, ^, ™, ʽ, ¦, ¥, -, ¼, Ý, ó, ⁒, x, [], ", [], #, S, a, I, p, p. These findings can serve as an alternative solution to safeguard message confidentiality, ensuring only the message owner and those with knowledge of the key can access it. The Gronsfeld Cipher cryptographic method can also enhance the security of the Quicksort algorithm, a cryptographic algorithm, by generating a more randomized text message that does not reveal patterns connecting it to the original text message.
