What would be the encoded version of the message using LZW compression technique

xxyz xxy xxyz xxyz xxyz

Expert Solution

Some Infomation about LZW encoding.

Encoded o/p :- It contain message sequence.

index :- It is unique index of a certain pattern

Initial LZW dictionary:- It contain unique letter with unique index in the given sequence.

Algo:

1. Start with initial letter of the given sequence check it already exist in the table or not . If yes, then add another next letter do the same thing.

2. Give this pattern a unique index. Write the index of the entry which match the new pattern upto second last letter in the encoded o/p row.

3.Now find the another new pattern and start with last letter of the previous pattern.

4. Repeat the these again until string exhaust.

Answer:

Encode message: 1 1 2 3 4 2 8 7 5 11 6

Note: In some other methods , They use assci codes of the letter as index but the procedure of the answer is same.

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.

Stream Cipher. A message is encoded by exclusive-or’ing each bit with a random bit stream. (In exclusive or, 0⊕0 = 0, 1⊕0 = 1, 0⊕1 = 1, and 1⊕1 = 0.) a. Recover the original message from the random stream and encrypted stream, by filling in the blanks in the “Recovered” and “ASCII” rows. (In the ASCII column, interpret the byte as an ASCII character and write the value in that row.) Message: ? ? ? ? ? ? ?...
