Throughput Analysis of Symmetric Algorithms
Today's world, for secure data transmission via Internet or any public network, there is no alternative to cryptography. The role of cryptography is most important in the field of network security. In this paper, we compare the various cryptographic algorithms. On the basis of parameter taken as time various cryptographic algorithms are evaluated on different audio and video files. Different audio and video files are having different processing speed on which various size of file are processed. Calculation of time for encryption and decryption in different audio and video file format such as .vob, .mp3 and .DAT, having file size for audio 1 MB to 10MB and for video 1MB to 1100MB respectively. Encryption processing time and decryption processing time are compared between various cryptographic algorithms which come out to be not too much. Overall time depend on the corresponding file size. Throughput analysis also done.
