Abstract

Di era digital, kebutuhan akan algoritma kriptografi yang andal semakin penting untuk melindungi data sensitif. AES-GCM dan ChaCha20-Poly1305 adalah dua algoritma populer yang digunakan, namun keduanya memiliki trade-off antara kinerja dan keamanan. Penelitian ini bertujuan mengevaluasi kedua algoritma melalui pengujian kinerja dan simulasi serangan timing. Pengujian kinerja dilakukan dengan mengukur waktu enkripsi dan dekripsi pada berbagai ukuran data, sedangkan simulasi serangan timing menilai kerentanan terhadap serangan tersebut. Hasil penelitian menunjukkan bahwa AES-GCM lebih lambat dibandingkan ChaCha20-Poly1305, terutama pada data berukuran besar, tetapi menawarkan ketahanan lebih baik terhadap serangan timing. Sebaliknya, ChaCha20-Poly1305 unggul dalam kecepatan, menjadikannya pilihan ideal untuk aplikasi dengan kebutuhan performa tinggi tanpa mengorbankan keamanan dasar.

Abstract

This study analyzes the responses of Micro, Small, and Medium Enterprises (MSMEs) in dealing with unfair business competition in the traditional food sector, particularly ketempling products in Kuningan Regency. The research employs a qualitative approach using interviews with two ketempling MSME actors as informants. The findings indicate that MSMEs experience competitive pressure, especially in terms of price competition and product similarity. Nevertheless, the business actors choose not to engage in unfair practices such as extreme price cutting or product imitation. Instead, they emphasize product quality, the use of high-quality raw materials, and improved consumer services as their main survival strategies. In addition, the utilization of social media and product diversification plays an important role in adapting to increasingly competitive market conditions, particularly in the post–COVID-19 period. This study concludes that business strategies oriented toward quality, innovation, and business ethics represent a sustainable approach for MSMEs to withstand unfair competition and build a positive business image among consumers.
