SUPER ENKRIPSI DENGAN MODIFIKASI VIGENERE CHIPER DENGAN TRANSPOSISI KOLOM KEDALAM SANDI MORSE UNTUK KEAMANAN PESAN

Abstrak

Text message security is a major concern in the digital era due to the risk of interception and unauthorized access. This study proposes a super encryption method by combining modified Vigenere Cipher, columnar transposition, and Morse encryption to enhance text message security. The encryption process begins with the Vigenere algorithm to generate the initial ciphertext, followed by columnar transposition, and concludes with conversion to Morse code. The results demonstrate that this method provides layered security that is difficult to penetrate, making it an effective solution for protecting digital communications from cyber threats. The strength of this method lies in its ability to synergize cryptographic algorithms, offering a higher level of confidentiality compared to conventional methods.
