1. How many bits would need to be added to DES’s key in order to double its average brute-force cracking time?
Homework Answers
The time and cost for a brute force attack is approximately 2^(16) more than for TripleDES, and under the assumption that 128 bits of strength is the required security goal, the recommended key exchange modulus size is about 700 bits longer.

I would like to insert a key deriving function into EAX mode, in order to hamper brute-force attacks for a key-size restricted cipher (56 bits). The modification inserts an identical multi-block pattern S behind the corresponding tweaks: Original: OMAC(T||...) where the 128-bit tweak T is either 0, 1, 2. Modification: OMAC(T||S||...) The state of the MAC behind S is different for disjunct tweaks, because the MAC's state behind S can be decrypted back to the original tweak, and identical states...

please explain how they solved this. in a simple way.
Example 5.1 How many padding bits must be added to a message of 100 characters if 8-bit ASCII is used for encoding and the block cipher accepts blocks of 64 bits? Solution Encoding 100 characters using 8-bit ASCII results in an 800-bit message. The plaintext must be divisible by 64. If MI and IPadl are the length of the message and the length of the padding 32 mod 64 This...
