Digital Signature
Weyde Lin · 2023
Abstract A digital signature uses cryptographic hashing functions and asymmetric cryptography to sign data. It also provides origin authentication, data integrity, and signer non-repudiation. The main idea is to generate a hash of the data using a cryptographic hashing function and then encrypt it by the signing party using its private key. As part of the verification process, the verifying party generates the hash of the data using the same cryptographic hashing function. With the increasing digitalization of business processes and other processes, the ability to apply and verify digital signatures will become increasingly important.
