Digital Signatures
Defined in 3 lectures. Each definition is in that lecture's terms.
Definitions are written by AI from each lecture’s transcript. The time opens the lecture where the lecturer explains it.
- Cryptographic primitives consisting of a secret signing key and a public verification key that allow anyone to verify message authenticity while only the key holder can sign.17:15What Can the Theory of Cryptography Tell Us About AI Verification?Shafi Goldwasser · Ruhr University Bochum
- A cryptographic mechanism allowing a sender (Alice) to sign a message using a private key such that anyone with the corresponding public key can verify authenticity and integrity.20:28Introduction to Hash-based Post-quantum Cryptography (PQC)Christof Paar · Ruhr University Bochum
- An application of public-key cryptography where a user encrypts a challenge using their private key, allowing a third party to verify their identity using their public key.
