Tecty Motors Pvt. Ltd. has recently deployed RFID technology in the vehicles which allows the car owner to unlock the car with t

he exchange of a valid RFID signal between a reader and a tag. Jamie, on the other hand, is a hacker who decided to exploit this technology with the aim of stealing the target vehicle. To perform this attack on the target vehicle, he first used an automated tool to intercept the signals between the reader and the tag to capture a valid RFID signal and then later used the same signal to unlock and steal the victim’s car.Which of the following RFID attacks Jamie has performed in the above scenario?A . RFID cloningB . Replay attackC . DoS attackD . Power analysis attack

Answer:

The answer is B.

Explanation:

Radio Frequency Identification (RFID) is a technology that uses radio waves to  secure objects, pair devices, tag them etc. and it is made up of a transmitter which emits radio waves and a receiver.

The example given in the question where Jamie listens to the communication between the RFID tag and the devide of the user and copies the information to later use it to gain access to the vehicle is an example of a replay attack.

Also called "eavesdropping & replay", the first part is the listening to the conversation to steal the data and the replay part is where he uses the information to gain access.

I hope this answer helps.

A laptop computer has two internal signals: An unplugged signal, which is '1' if the laptop's power supply is connected, and '0'
Brums [2.3K]

Answer:

The correct usage is a NOR gate which is indicated in the explanation.

Explanation:

The truth table for the given two signals, namely

p=unplugged signal

q=low battery signal

can  form a truth table of following form

Here p has 2 states

1 if the power supply is connected

0 otherwise

Similarly q has 2 states

0 if the battery has reached almost zero state

1 otherwise

As the condition for the Hibernate Signal is given as to only activate when the battery is low and the power supply is not connected. This indicate that the value of Hibernate signal should be 1 when both p and q are 0.

Using this condition, the truth table is formed as

unplugged signal | low battery signal |  Hibernate Signal

            0               |                 0             |             1

            0               |                 1              |             0

            1                |                 0             |             0

            1                |                 1              |             0

Now the truth table of NOR is given as

a    |     b    |  a or b   |   ~(a or b)

0    |     0    |      0      |        1

0    |     1     |      1       |        0

1     |     0    |      1       |        0

1     |     1     |      1       |        0

This indicates that the both truth tables are same thus the NOR gate is to be used for this purpose.
