PENGAMANAN CITRA DIGITAL MENGGUNAKAN ALGORITMA KRIPTOGRAFI RC4
Keywords:
Citra Digital, Kriptografi, RC4, EnkripsiAbstract
The increased use of digital images in communication and social media raises the risk of interception, manipulation, and unauthorized access. This study evaluates the security of JPEG and PNG formatted images using an enhanced RC4 cryptographic algorithm through longer key lengths, key randomness, and the use of salt. The objectives include the implementation of RC4 on images, the assessment of the security level of the encryption results, and testing resilience against brute force and dictionary attacks. It is hoped that strengthening RC4 will enhance security without sacrificing the efficiency of the encryption process for visual media.
