Abstract

Keamanan dan kerahasiaan dalam berkomunikasi menjadi suatu kebutuhan agar informasi yang dikirim dan diterima tidak disalahgunakan oleh pihak-pihak yang kurang bertanggung jawab. Keamanan dan kerahasiaan informasi dapat dijaga dengan memanfaatkan kriptografi. Kriptografi tidak hanya menyediakan alat untuk keamanan informasi, tetapi juga sekumpulan teknik yang berguna untuk keamanan dan kerahasiaan informasi. Salah satu metode enkripsi dan dekripsi yang dapat digunakan yaitu algoritma caesar chiper. Hanya saja algoritma caesar chiper mudah untuk dipecahkan sehingga pada jurnal ini penulis meningkatkan keamanan dari suatu pesan teks dengan memodifikasi algoritma caesar chiper dalam bentuk sandi morse.   Kata Kunci :Keamanan Pesan Teks, Algoritma Caesar Chiper, Sandi Morse

To know the factors influencing the acceptance of CBT can be known by using TAM method 3. The significant standard used in this research is 5%. In accordance with the results of research, then obtained the factors that affect the acceptance of the use of CBT is Job Relevance, Output Quality, and Perceived Ease of Use significant effect on Perceived Usefulness. Computer Anxiety has a significant effect on Perceived Ease of Use. Interactivity, Honesty, Perceived Usefulness, and Perceived Ease of Use have significant effect on Behavioral Intention. Behavioral Intention has significant effect on Use Behavioral.
