Earlier in the class we discussed how a Meet in the Middle attack made double-DES (encrypting something twice in a row with two separate keys of DES) not nearly as secure as we might think. This came at the cost of storing many possible decryptions in a table. For this question I want you to calculate how much storage space it would take to store the information necessary to do a meet in the middle attack on double-AES (of 128 bits). State any assumptions you have to make. This storage size should be in gigabytes. This might be a large number.

Answer:-
To convert 2^{113} bits to gigabyte we need to divide 2^{113} /8000000000. This will give you the answer in gigabyte which is ofcourse a large number.

Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
