Alvin Mustafa, Hendrawan Hendrawan · 2016
Nowadays, many algorithms in cryptography area has been developed. Choosing the appropriate algorithm and dealing with its tradeoff, require a specific analysis. One of the examples is calculating the optimum encryption algorithm in video encryption. There are various ways to encrypt the video, depend on encryption algorithms (DES, Triple DES, Blowfish, AES, etc), modes of operation (ECB, CBC, CFB, OFB, CTR, etc), and padding modes (ISO10126, PKCS5, or without padding). The purpose of this paper is to calculate the best combination of encryption method regarding to processing time, performance, security, dynamism of system and impact from error propagation using two layer of AHP. The first AHP is to determine encryption algorithm and the second AHP is to determine modes of operation. The conclusion of this paper is the author suggest to use combination of AES/CTR/PKCS5Padding as the optimum method to encrypt the video. In this paper, also include the sample of video before and after encryption method.
