Message integrity and authentication
Digital signatures are a cryptographic technique analogous to hand-written signatures. Sender uses his/her private key to cypher the message. Receiver verifies message signed by Sender by applying Sender’s public key to the message.
Receiver thus verifies that:
- Sender signed the message and no one else
Non-repudiation:
- Receiver can take the message and signature to court and prove that the Sender signed the message
