Computer Science Question

Bit Level Manipulation

Write a simple bit manipulation code that allows users to indicate decimal number and bit system (i.g 4/8/16/32/64) in which binary number will be outputted. Apart from that you have to calculate the corresponding one’s and two’s complement of the decimal number. However, the only named variables you may use are pointer variables; all others must be anonymous variables.

Pay close attention to the following aspects:

  • error checking
  • loop function
  • pointer variables
  • code efficiency(smart code), readability, documentation.

 

One-time pad (OTP) encryption is provably secure. It would be expected that an unbreak- able encryption method would be highly desirable yet it is not widely used. Describe what makes OTP hard to use in practice.

Question 1

One-time pad (OTP) encryption is provably secure. It would be expected that an unbreak- able encryption method would be highly desirable yet it is not widely used. Describe what makes OTP hard to use in practice.

Question 2

Comparing secret-key and public-key encryption, what is the main advantage that the latter offers over the former?

Question 3

The definition of a Shift Cipher can be expressed as follows:

Def. Let x, y, k ∈ Z26 with the encryption operation as ek(x) ≡ x + k mod 26 and the decryption operation as dk(y)  y – k mod 26.

Given the provided letter encoding, what would be the encoding of the plaintext word ATTACK after applying a shift cipher with a k=17?

Question 4

Assume a hash function H(m) which is collision resistant. This particular function maps a message of arbitrary bit length into an n-bit hash value. Can we assume that for all messages

m, mj with m

m’, we have H(m)

H(mj)? You must explain your answer to receive credit.

 

(Hint: see textbook section about Secure Hash Functions.)

 

Question 5

Develop a single program using any programming language (e.g. Java, Python, C++, etc.) that:

  1. Encrypts and decrypts a message using the Cesar’s The user encrypting the message is prompted to enter a message and then a key that indicates the displacement. The user decrypting the message is prompted to enter the encrypted message and the key.
  2. (Decrypts and displays all (26) possible
