Using a technique called randomized encryption, convert textbook AES and RSA to a secured version with an initialization vector (IV). Assume we have a message (m) with 128 bits, show how to encrypt (m) with secured AES. Explain why IEEE 802.11 (i.e., WEP) is not secure due to the inappropriate usage of an IV.

Perform a Web search for “Announcing the Advanced Encryption Standard (AES).” Read this document, which is a FIPS 197 standard. Write a short overview of the development and implementation of this cryptosystem. Your response must include the type of Algorithm used, the size of data blocks that can be processed, and the lengths of the cipher keys.

Applying what you have learned... When politicians make claims that we need to spend a large amount of money to achieve a goal, the claim is often made without legitimate evidence to support a claim that a given program will have a particular result. Let's say that a politician wants to implement a nation-wide education program. The politician gave four examples of schools that used the program: scores at the schools increased 0.5, 1, 2, and 2.5 points respectively (the...
