Here, we are investigating the block cipher AES (Rijndael) which has a key length of 128 bits. Assume that we have a special purpose chip which searches (5.107) keys per second. We parallelize 100,000 of the chips. How long does an average key search take? Relate this time to the age of the universe (about 10 years)?
