WebCryptographic communication and authentication Paul Krzyzanowski Introduction to cryptography We will refer to a message that is readable, or not encrypted, as plaintext, cleartext and denote it with the symbol M. The process of disguising a message to hide its substance is called encryption. We will represent this operation as E(M). WebCryptographic nonce example Cryptographic 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.
