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.

) Consider a router that interconnects four subnets: Subnet 1, Subnet 2, Subnet 3 and Subnet 4. Suppose all of the interfaces in
erik [133]

Answer:

Check the explanation

Explanation:

223.1.17/24 indicates that out of 32-bits of IP address 24 bits have been assigned as subnet part and 8 bits for host id.

The binary representation of 223.1.17 is 11011111 00000001 00010001 00000000

Given that, subnet 1 has 63 interfaces. To represent 63 interfaces, we need 6 bits (64 = 26)

So its addresses can be from 223.1.17.0/26 to 223.1.17.62/26

Subnet 2 has 95 interfaces. 95 interfaces can be accommodated using 7 bits up to 127 host addresses can represented using 7 bits (127 = 27)

and hence, the addresses may be from 223.1.17.63/25 to 223.1.17.157/25

Subnet 3 has 16 interfaces. 4 bits are needed for 16 interfaces (16 = 24)

So the network addresses may range from 223.1.17.158/28 to 223.1.17.173/28
