Let M be the plaintext message M = MALAYSIA and the private key, K = ISSOGOOD a) Using the appropriate steps of DES operation, what is the final output of the key for round 1 (hint: you have to use the circular left shift and permutation compression (PC) table provided below). b) For round 1, please provide your output for the XOR operation of plaintext and the key, according to the DES operation. c) Based on the output of 4(b), explain the next process using the S-box table, and show the output from this operation. d) Based on the output of 4(c), explain the next process using a straight permutation table, and show the output from this operation.
This is the definition of data compression: What do you mean by that? (a) Specify. Detail two distinct compression techniques that you know about. Specify the roles that each one plays. Explain the differences between data compression and encryption by using the following points:
When moving images are sent across a network, redundancy is inevitable. In encoding, we employ two kinds of redundancy. With regards to compression, which of the following two methods should be used?
Consider a SEC code that protects 8-bit words with 4 parity bits. If we read the value0xABC, is there an error? If so, correct the error.Note: 0xABC = 1010 1011 1100Hint: Decode the 12-bit encoded data and find if there is an error.
3. A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Propose your own Roll as data bits (e.g roll 1 to 100) and show how the sender adds the parity bits and write the final code word that will be sent. Value of Key is 1011 (derived from polynomial function). Also show in the receiver side that the correct data is received.
a) Consider the (7,4) hamming code with data word 1111 and evaluate the 7-bt composite code word (use even parity). b) Assume the stored composite code from memory is 1010001. Evaluate the parity bits of the stored code, find the bit position in error, and correct it if it is correctable (use even parity).
You are given a text file of size 60 MB, which is to be encrypted using steganography in the low-order bits of each color in an image file. What size image would be required in order to encrypt the entire file? What size would be needed if the file were first compressed to a third of its original size? Give your answer in pixels, and show your calculations. Assume that the images have an aspect ratio of 3:2, for example, 3000 × 2000 pixels.

3. So I am studying Word Aligned Hybrid compression. All of it seems pretty straightforward until I stumbled upon the last part. Say you have a 8-bit compression but you only have for example 2, 3, 4, or some number of bits less than the word size. how do you "compress" or rack on the remaining bits? say we are doing a size 8 on the example: 0101000-00000000-00000000 I understand that the first 7 are taken literally then there follow 2 runs of 0's. But then what do you do about the remaining 3 or so bits? what would the compressed output look like?
Discuss the steps on how Huffman encoding algorithm is use in determining the efficiency of data compression.
Question 3 a i. briefly describe three methods that computers can use to check for error detection if the text being transmitted is “HEY”. ii. the weighted method is ideal for decimal-to-binary conversions because of its efficiency. However, it could also be used for other bases. Briefly describe how the weighted method could be used to implement a conversion from decimal to tenary.
