Analisis Kriptografi Simetris AES dan Kriptografi Asimetris RSA pada Enkripsi Citra Digital

Abstract

Semakin berkembangnya teknologi dan informasi, semakin besar pula resiko atau kejahatan yang terjadi. Salah satu kejahatan yang sering terjadi adalah pemalsuan dan pembajakan informasi yang dikirim. Oleh sebab itu, untuk menjaga kerahasiaan informasi tersebut dibutuhkan sebuah teknologi yang dapat merahasiakan informasi yang dikirim, seperti kriptografi. Berdasarkan kunci yang digunakan, algoritma kriptografi terdiri dari kriptografi simetris dan kriptografi asimetris. Salah satu contoh algoritma kunci simetris adalah algoritma Advanced Encrypted Standard dan kunci asimetris adalah Rivest-Shamir-Adleman. Pada proyek akhir ini, dibangun sebuah sistem enkripsi dan dekripsi citra digital untuk menganalisis performa kedua algortima tersebut. Jenis citra yang digunakan yaitu citra RGB dengan berbagai ukuran yang berbeda. Hasil yang didapatkan pada sistem ini adalah, algoritma AES menghasilkan cipher image yang lebih baik namun algoritma ini membutuhkan waktu proses yang lebih lama dibandingkan dengan algoritma RSA. Kinerja kedua metode dihitung dengan mencari nilai Mean Square Error (MSE) dan Peak Signal to Noise Ratio (PSNR) citra. Dari rata-rata nilai MSE dan PSNR yang didapatkan, ditemukan nilai MSE dan PSNR yang sempurna pada algoritma RSA dengan nilai MSE = 0 dan PSNR = inf.
