10. What is the chance that someone could use the "DES Cracker"-like hardware to crack an AES key? (Read assumptions below) In the late 1990s, specialized "DES Cracker" machines were built that could recover a DES key after a few hours. In other words, by trying possible key values, the hardware could determine which key was used to encrypt a message With the currents technology let's assume that one could build a machine that could recover a DES key in a second (i.e., try 26 keys per second). How many years it takes to crack the AES algorithmm NB: 1 year -31536000 seconds What do you think about the security level of AES? To put that into perspective, the universe is believed to be less than 20 billion years old
