The so-called digital signature is the use of a cryptographic operation generated by a series of symbols and code to form an electronic password to sign, instead of writing a signature or seal, for this electronic signature in the technical algorithm can also be verified, the accuracy of the verification is in the physical world with the manual signature and stamp verification is not comparable. Digital signatures are defined in the Iso7498-2 standard as: Some data attached to a data unit, or a password transformation on a data unit, which allows the receiver of the data unit to confirm the integrity of the source and data unit of the data unit and to protect the data from forgery by the person (for example, the recipient). The American Electronic Signature Standard (DSS,FIPS186-2) interprets the digital signature as follows: Using a set of rules and a parameter to calculate the results of the data, this result can confirm the identity of the signer and the integrity of the data. According to these definitions, digital signature has become one of the most widely used, most mature and most operable electronic signature methods in e-commerce and e-government. It is a standardized program and a scientific method for identifying the identity of the signer and the recognition of an electronic data content.
