WebSep 20, 2024 · This is known as non-repudiation, since the signatory cannot easily repudiate the signature at a later time. The digital signatures standard was proposed by NIST and is defined in FIPS 186-4. Digital signatures employ asymmetric cryptography and they provide a layer of validation and security to messages sent through a non-secure channel. opengauss-数据查询 select

WebNon-repudiation – Prevents a user from denying prior commitments or actions. Cryptography uses a number of low-level cryptographic algorithms to achieve one or more of these information security goals. These tools include encryption algorithms, digital signature algorithms, hash algorithms, and other functions.

WebMACs do not provide non-repudiation because in symmetric cryptography the receiver also has the same secret key, so there's no way for the receiver to prove that the sender and not the receiver signed the message.
