Cryptography non repudiation
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. As emphasized previously, using a shared key for authentication requires the shared key to be properly secured.

Data integrity, authenticity, and non-repudiation. Encrypted data does not mean the data can not be manipulated (for example, repeated, deleted, or even altered). To rely on data, you need ... WebNon-repudiation is the guarantee that no one can deny a transaction. The term "non-repudiation" is frequently used for digital signatures and email messages. When a data hashing algorithm is combined with public or private keys, data origination authentication can be achieved.
WebNonrepudiation is achieved through cryptography, like digital signatures, and includes other services for authentication, auditing and logging. In online transactions, digital signatures ensure that a party cannot later deny sending information or deny the … WebWhen non-repudiation is required for a digital signature key, it means that the signature that has been created by that key has the support of both the integrity and source authentication services of a digital signature.
