AP CSP (encryption)

Biologists often attach tracking collars to wild animals. For each animal, the following geolocation data is collected at frequent intervals:

Time

Date

Location of animal

Which of the following questions about a particular animal could NOT be answered using only the data collected from the tracking collars?

• In what geographic locations does the animal typically travel?

• Approximately how many miles did the animal travel in one week?

• Does the animal travel in groups with other tracked animals?

• Do the movement patterns of the animal vary according to the weather?

A coffee shop is considering accepting orders and payments through their phone app and have decided to use public key encryption to encrypt their customers’ credit card information. Is this a secure form of payment?

• Yes, public key encryption is built upon computationally hard problems that even powerful computers cannot easily solve

• Yes, public key encryption is secure because it transmits credit card information in binary

• No, public key encryption allows the credit card information to be read by the public

• No, the Internet protocols are open standards and thus everything sent over the Internet is sent “in the clear”

Which of the following statements best describes the properties of public key encryption?

• Public key encryption makes use of certain types of problems which are easier for humans to solve than computers

• Public key encryption makes use of mathematical problems which no algorithm can be used to solve

• Public key encryption is an encryption method which relies on separate keys for encrypting and decrypting information

• Public key encryption is a highly secure encryption scheme that in which a single shared key is used by both the sender and receiver of the message

Choose the answer that is NOT a feature of public key cryptography:

• Allows secure communication without establishing a “shared” encryption key ahead of time

• A key for decrypting is never made public

• Using public key guarantees that only the intended recipient can decrypt the message

• A public key database ensures 3rd party accountability of security

Which of the following are true statements about digital certificates in Web browsers?

I. Digital certificates are used to verify the ownership of encrypted keys used in secured communication

II. Digital certificates are used to verify that the connection to a Website is fault tolerant

• I only

• II only

• both I and II

• neither I or II

In public key cryptography, the sender uses the recipient’s public key to encrypt a message. Which of the following is needed to decrypt the message?

• recipient's public key

• recipient's private key

• sender's public key

• sender's private key

Which of the following is an underlying assumption that is made when Moore’s law is used?

• As computer hardware improves, future computers will be able to run faster than current computers.

• As computer hardware improves, the number of cybersecurity concerns will increase.

• As computer hardware improves, the algorithms used in programs will become more efficient.

• As computer hardware improves, developers will become more skilled at writing code.

Which of the following describes how a distributed denial-of-service (DDoS) attack is most likely to compromise an online store’s Website?

• By preventing customers from placing orders

• By making it difficult for the site to safeguard customer login information

• By causing incorrect information about services to be displayed

• By preventing the store from filling previously placed orders
