Abstract
Some important security needs include authentication, confidentiality, integrity, non-repudiation, and user privacy. Many security systems include these required protections for information transmission. The encryption process is one of the most important security measures. Many secure encryption algorithms are based on different keys and key lengths to ensure a high degree of security. GIF file format is common file format that is used in several application, securing these files through transmission is imperative. In this paper, an efficient method for encryption GIF file is proposed based on using modified present algorithm, modified ZUC stream cipher, and an efficient method for key generation based on simulation of a dynamic billiard table to generate number that control the encryption results. The proposed method tests through experiments on tests the randomness of generated sequences, the quality of encrypted image MSE, PSNR, SSIM , entropy, the time consuming for encryption, and the differential attack test through NPCR and UCAI. All experiments satisfy the standard results and the method could used in all types of multimedia file format.
