A digital signature uses asymmetric (public key) cryptography to provide authentication, integrity, and non-repudiation. The sender signs using their private key; the receiver verifies using the sender's public key. Sender side: 1. Message: Sender has the original plaintext message $M$. 2. Hashin...
