Pengujian dilakukan pada dua jenis data, yaitu data sensor (suhu, kelembapan, arus, tegangan) dan data string dengan panjang bervariasi dari 8 hingga 100 karakter. Hasil menunjukkan bahwa kedua algoritma berhasil melakukan enkripsi dan dekripsi dengan tingkat keberhasilan 100%. Waktu enkripsi RSA rata-rata 0,0104 detik dan dekripsi 9,1284 detik, sedangkan RC 4 mencatat waktu enkripsi 0,1894 detik dan dekripsi 0,1616 detik. Namun, pada data string pendek hingga menengah, RC 4 mencatat waktu enkripsi lebih cepat (0,027–0,132 ms) dibanding RSA (0,007–0,035 ms), namun menjadi lebih lambat untuk data besar (RC 4: 0,389 ms vs RSA: 0,092 ms pada 100 karakter). Dari sisi keamanan, pengujian brute force menunjukkan bahwa algoritma RSA memiliki ketahanan tinggi karena tidak berhasil dibobol hingga batas waktu pengujian selama 952,871–1001,652 s (±15– 16 menit) pada berbagai variasi pesan. Sebaliknya, RC 4 lebih rentan, dengan kunci berhasil ditemukan dalam rentang waktu 52,871–85,983 s (±0,88–1,43 menit), dan seluruh pesan berhasil didekripsi setelah kunci ditemukan. Dalam aspek efisiensi energi, RC 4 mengonsumsi energi lebih rendah (0,233–0,322 joule) dibanding RSA (0,2954–0,4024 joule) per siklus pengiriman data. Berdasarkan hasil tersebut, RC 4 lebih unggul untuk efisiensi waktu dan energi dalam komunikasi data pendek, sedangkan RSA unggul dalam keamanan distribusi kunci pada sistem yang memerlukan perlindungan tinggi.","\u003Cp>Wireless Sensor Network (WSN) merupakan teknologi jaringan nirkabel yang digunakan untuk mengumpulkan dan mengirimkan payload data, namun rawan terhadap intersepsi data sehingga diperlukan pengamanan menggunakan kriptografi.
