1.3. we consider the long-term security of the advanced encryption standard (aes) with a key length of 128-bit with respect to exhaustive key-search attacks. aes is perhaps the most widely used symmetric cipher at this time. 1. assume that an attacker has a special purpose application specific integrated circuit (asic) which checks 5 · 108 keys per second, and she has a budget of $1 million. one asic costs $50, and we assume 100% overhead for integrating problems 25 the asic (manufacturing the printed circuit boards, power supply, cooling, how many asics can we run in parallel with the given budget? how long does an average key search take? r

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. internet speed levels of "fast comma " "medium comma " and "slow" choose the correct answer below. a. the ordinal level of measurement is most appropriate because the data can be ordered comma but differences left parenthesis obtained by subtraction right parenthesis cannot be found or are meaningless. nothing nothing nothing nothing nothing b. the interval level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is no natural starting point. c. the nominal level of measurement is most appropriate because the data cannot be ordered. nothing d. the ratio level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is a natural starting point.
