- Suppose that in an RSA Public Key Cryptosystem, the public key is e=13,m=77. Encrypt the message "go for it" using two-digit blocks and the 27-letter alphabet A from Example 2. What is the secret key d? Example 2 Translation Cipher Associate the n letters of the "alphabet" with the integers 0,1,2,3.....n1. Let A={ 0,1,2,3.....n-1 } and define the mapping f:AA by f(x)=x+kmodn where k is the key, the number of positions from the plaintext to the ciphertext. If our alphabet consists of a through z, in natural order, followed by a blank, then we have 27 "letters" that we associate with the integers 0,1,2,...,26 as follows: Alphabet:abcdef...vwxyzblankA:012345212223242526arrow_forwardSuppose that in an RSA Public Key Cryptosystem, the public key is.

- Create a maths problem and model solution corresponding to the following question: “Given the following complete Sum of Products produce a Karnaugh map and find the minimal Sum of Products, then draw the corresponding logic circuit” Use 4 boolean values, and label them g, h, i and j. Your problem should make use of at least 7 products, one of which should be “g’h’ij”. . Ensure the minimal Sum of Products is different to the complete Sum of Products initially provided. You can find similar problems in Tutorials 3 and 4, but must not use any of them in constructing your own.arrow_forwardTweet, a quality control engineer of a large computer firm, inspects a large shipment of printed circuit boards (PCBs). The shipment of 1000 PCBs were inspected for defects, such as misplaced components or the application of too much solder paste. Tweet found that 750 of the PCBs have no defects, 100 have one defect each, 75 have two defects each, 50 have three defects each, and the rest have 5 defects each. Let X be the number of defects found in a PCB. What is P(X =2)? Group of answer choicesarrow_forwardQ26. For the function T(w, x, y, z) = 2(0, 1, 2, 3, 4, 6, 7, 8, 9, 11, 15). Design a circuit which will find the 2's complement of a 4-bit binary number. Use one full adder, 3 half adders and any ad- ditional gates (D).arrow_forward
- Let Z denote the set of integers. If m is a positive integer, we write Zm for the system of "integers modulo m." Some authors write Z/mZ for that system. For completeness, we include some definitions here. The system Zm can be represented as the set {0, 1,..., m - 1} with operations (addition) and (multiplication) defined as follows. If a, b are elements of {0, 1,..., m - 1}, define: ab the element c of {0, 1,...,m - 1} such that a +b-c is an integer multiple of m. a b = the element d of {0, 1,..., m - 1} such that ab -d is an integer multiple of m. For example, 30 4 = 2 in Z5, 303= 1 in Z4, and -1 = 12 in Z₁3. To simplify notations (at the expense of possible confusion), we abandon that new notation and write a + b and ab for the operations in Zm, rather than writing ab and a b. = Let Q denote the system of rational numbers. We write 4Z for the set of multiples of 4 in Z. Similarly for 4Z12. Consider the following number systems: Z, Q, 4Z, Z3, Z8, Z9, 4Z12, Z13. One system may be…arrow_forwardShow all workingarrow_forwardThe Human Resources office in a company observes the pattern of absences of employees by days of the week.
