When presented with the same card, the output is always the same: In the serial output there is no evidence of a counter, one-time password, or any other mechanism for prevention of replay attacks.
According to the problems in the literature review outlined above, an improved protocol is proposed which is also based on the hash function, and it can prevent illegal access, eavesdropping, tracking, impersonation and replay attacks.
Based on symmetric key cryptography and one way hash function, Song [9] suggested an efficient smart card authentication scheme and claimed that the scheme is secure against impersonation attack, parallel session attack, replay attack and modification attack.

Therefore, replay attacks cannot work in our scheme.
The time concurrency mechanism is used in some authentication schemes using smart cards to resist replay attacks.
A Relay attack in its broad-spectrum is a type of attack related to man-in-the-middle and replay attacks, in which an attacker relays verbatim a message from the sender to a valid receiver of the message.
Replay attacks, denial of service attacks, signal/media manipulation and phone hacking attacks, like those in the news over the past month, are no longer threats.
It also allows protection against replay attacks and man-in-the middle attacks.
0 update is more bandwidth efficient than current messaging systems, includes bidirectional authentication to prevent spoofing, and contains message sequence numbers to prevent replay attacks.
As EntryProtect provides true end-to-end encryption of all transmitted data (beyond the scope of SSL), it also provides full protection against MITM and replay attacks.
