In this problem, we want to compare the computational performance of symmetric and asymmetric algorithms. Assume a fast public-key library such as OpenSSL [132] that can decrypt data at a rate of 100 Kbit/sec using the RSA algorithm on a modern PC. On the same machine, AES can decrypt at a rate of 17 Mbit/sec. Assume we want to decrypt a movie stored on a DVD. The movie requires1GByteofstorage.Howlongdoesdecryptiontakewitheitheralgorithm?
