  • It is also called as 2FA, which is an extra security layer that is used when logging into websites or applications.
  • First, the user has to provide his/ her username and password.
  • Second, the user will be provided with another form of authentication method like text message authentication or voice based authentication.
  • The three factors that are involved in two-factor authentication include:
    • Knowledge
      • It is the information that is known to the user like PIN number.
    • Possession
      • It is nothing but the thing that the user has like an ATM card.
    • Inherence
      • It is something that the user contains like biometric characteristics.

Simulate on a vertical time axis (with events labeled with the senders names A-D) the contention period of FOUR equally distanced Ethernet stations that all attempt to transmit at T=0 a minimally sized frame, in the style of the binary Exponential Backoff Algorithm. Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2). Use as coin flip (source of randomness) an ID written in binary. use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown. Start be writing the ID, which is 904012207 As example of the expected answer format,  with the random sequence R:   100101010101001011001010 01 01011  10010 1010 1010 010…
