WebReplay Cryptography Attack The next cryptography attack that is going to be discussed is replay attacks. These possible types of attacks in cryptography are basically targeting cryptographic algorithms that come without any kind of temporal security.

WebCryptographic nonce is used in authentication protocols to defend against replay attacks. Replay attacks are when an attacker intercepts authentication data in transit and uses it later to gain access to the protected network. E-commerce sites typically use a nonce to assign originality to each purchase.
