Digital signatures have a potential weakness due to lazy users. In e-commercetransactions, a contract might be drawn up and the user asked to sign its SHA-1 hash.If the user does not actually verify that the contract and hash correspond, the user mayinadvertently sign a different contract. Suppose that the Mafia try to exploit thisweakness to make some money. They set up a pay Web site (e.g., pornography,gambling, etc.) and ask new customers for a credit card number. Then they send over acontract saying that the customer wishes to use their service and pay by credit cardand ask the customer to sign it, knowing that most of them will just sign withoutverifying that the contract and hash agree. Show how the Mafia can buy diamonds froma legitimate Internet jeweler and charge them to unsuspecting customers.

The utility company in the city of Harperville serves 20,000 residential addresses. The company wants to gauge interest in a “Beat the Peak” program which offers consumers a discount in exchange for limited electricity usage during peak hours. Unknown to the utility company, 18% of its 20,000 residential customers would participate in such a program. Since the company does not know the level of interest among its customers, the company selects every 40th account from an alphabetical listing of residential account holders, starting with the 23rd name. Of the 500 subscribers selected, 16% express interest in the “Beat the Peak” program. 1a) What type of sampling did the utility company employ? A. simple random sample B. systematic C. cluster D. stratified E. Voluntary response F. Convenience G. Judgement 2b) The utility company divides its service area into 5 zones. If the company had randomly selected 100 customers from each zone, which type of sampling would they have employed?…
A corporation wants to determine the best transportation option based on a number of factors, which include passenger comfort, number of transfers, travel time, and cost. Let X1 be a binary variable where X, = 1 means that a direct long-haul flight will be chosen while X1 = 0 means that a non-direct long-haul flight will be chosen. Furthermore, let X2 be also a binary variable where X2 = 1 means that a Business Class seat was chosen while X2 = 0 means a Premium Economy seat was chosen. If the option of choosing a Business Class seat will only happen when a direct long-haul flight is chosen, what would be the appropriate expression for this constraint? O a. X1 + X2 < 1 O b. X1 + X2 = 1 O c. X2 – X1 <1 O d. X, – X1 = 1
Suppose the RSA system that is used for sending secret messages has private key (15, 3) and the cipher text "3" is received. What was the plain text sent? 7 O 9 O 12
A computer store sells three types of microcomputers, brand A, brand B, and brand C. Of the computers they sell, 60% are brand A, 25% are brand B, and 15% are brand C. They have found that 20% of the brand A computers, 15% of the brand B computers, and 10% of brand C computers are returned for service during the warranty period. If a computer is returned for service during the warranty period, what is the probability that it is a brand A computer? A brand B computer? A brand C computer? The probability that it is a brand A computer is (Type a decimal. Round to three decimal places if needed.) The probability that it is a brand B computer is (Type a decimal. Round to three decimal places if needed.) The probability that it is a brand C computer is (Type a decimal. Round to three decimal places if needed.)
The Honest Lock Co. plans to introduce what it refers to as the “true combinationlock.” The lock will open if the correct set of 3 characters from the following (familiar) set of 26 characters{a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z}is entered (in any order). If it is allowed that any or all of the characters may be the same, what is the total number ofcombinations possible?
A murder scene is found with two types of blood - that of the victim and that ofthe murderer. As luck would have it, the unidentified blood has an incredibly rareblood disorder, only found in 1 in every million men. The capital and surroundingareas have a population of 20 million - and the police are sure the murderer isfrom the capital. The police have already started cataloging all citizens' bloodtypes for their new super crime-database. They already have nearly 1 millionmale samples in there - and bingo - one man, Mr XY, is a match. He is promptlymarched off to trial, there is no other evidence, but the jury are told that the oddsare 1 in a million that he is innocent. He is duly convicted. The question is, howlikely is it that he did not commit this crime?

A company’s security policy requires each employeeto have an ID number. The policy also requires eachperson’s ID number to be printed on their ID card.Under the policy, each ID number must contain sixdigits, and no digit can be used more than once in aparticular ID number. Assuming that the companyhas 152,000 employees, is this a sensible policy?
Flowering plant species can be subject to inbreeding, through self-fertilization. Some species have adaptations that help to avoid this inbreeding, through asymmetric flower structures. If the flower structures are “right-handed”, then a pollinator visiting the right-handed flower will get pollen on its left side, and thus, only be able to deposit the pollen on a left-handed flower that it visits later on. [Similarly, pollinator visits to left-handed plants will result in pollen deposits on right-handed plants.] You are interested in studying a particular plant species called Lupinus perennis, that demonstrates handedness, and you wish to know whether one type of handedness is more prevalent than the other (e.g., are left-handed plants more prevalent than right-handed plants?) You sample 30 L. perennis plants, and find that 20 plants are right-handed, and 10 plants are left-handed. Is one type of handedness more prevalent than the other? What is your null hypothesis? Report the…
As the customer base at OHaganBooks.com grows, IT manager Ruth Nabarro is thinking of introducing identity codes for all the customers, using capital letters and/or numbers. Help her answer the following question. It appears that Nabarro has finally settled on codes consisting of two letters followed by two digits. For technical reasons, the letters must be different, and the first digit cannot be a zero. How many different customers can be identified?
Four salesmen play "odd man out" to see who pays for lunch. They each flip a coin, and if there is a salesman whose coin doesn't match the others he pays for lunch. To clarify, the "odd man" must get heads while the other three get tails OR he must get tails while the other three get heads. Of course, since it is possible for two men get heads and two men get tails, not all flips will result in finding an "odd man". If this occurs the salesmen would be forced to flip again. What is the probability that there is an "odd man" the first time they flip?
A user is allowed to create an 8-digit password, but it must satisfy the following requirements: The first 2 spots must be different letters of the alphabet (case is not sensitive) The next 4 spots must be different numbers from the set {0-9} The last 2 spots must be different non-alphanumeric symbols from the set {# , @, $,%} How many passwords are possible?
