Which provides data authentication protection from replay attacks?
IPSec
IPSec provides confidentiality and integrity protection for transmitted information, authentication source and destinations, and anti-replay protection. Two main network protocols, Encapsulating Security Payload (ESP) and Authentication Header (AH), are used to achieve this goal.
What is replay authentication?
A “replay-resistant” authentication mechanism is one that prevents someone who is snooping on network traffic from being able to store and re-use at a later time.
Does TLS 1.2 prevent replay attacks?
The SSL/TLS channel itself is protected against replay attacks using the MAC (Message Authentication Code), computed using the MAC secret and the sequence number. (The MAC mechanism is what ensures the TLS communication integrity).
What is used to overcome the replay attacks in IPsec?
To overcome this problem, IPSec uses an Authentication Header (AH) to digitally sign the entire contents of each packet. This signature provides 3 benefits: 1) Protects against replay attacks. This is what we call a replay attack.
Is there a way to replay an HTTPS request?
To intercept and replay an HTTPS request (the classic HTTP replay attack), you would have to be able to decrypt the SSL encryption of the traffic AFAIK. My guess is, you cannot do that.
How does a replay attack work on encrypted messages?
Encrypted messages carry “keys” within them, and when they’re decoded at the end of the transmission, they open the message. In a replay attack, it doesn’t matter if the attacker who intercepted the original message can read or decipher the key.
How does replay attack work on SSL / TLS authentication?
Thus in summary: replay attacks against SSL/TLS are not possible and this is also not claimed in the text you cite. The text instead talks about having the original plain (not encrypted) data and sending these inside a new SSL/TLS connection – but this is not a replay at the SSL/TLS level.
How does https protect against re play attacks?
HTTPS specifically defends against re-play attacks of raw cipher text and prevents the attacker from knowing the contents of the request. It is important to note that HTTPS does not defend against CSRF.
