Description

technical field [0001] The invention relates to a digital signature signing device and method. Background technique [0002] In a computer network, since all participating entities do not have face-to-face contact, digital signatures are usually used to indicate their identities. [0003] Digital signature is one of the basic technologies to realize electronic transaction security. A digital signature is defined in the ISO7498-2 standard as: "Some data attached to a data unit, or a cryptographic transformation made to a data unit, which allows the recipient of the data unit to confirm the source of the data unit and the data unit integrity, and protects data against forgery by persons such as recipients". The US Electronic Signature Standard (DSS, FIPS186-2) explains digital signatures as follows: "Using a set of rules and a parameter to calculate the result of the data, this result can confirm the identity of the signer and the integrity of the data". Digital signature c...
