Electronic signature authentication method based on ellipse curve signature algorithm

Abstract

The invention provides an electronic signature authentication method based on an ellipse curve signature algorithm, which comprises the following steps that: a user utilizes a digital signature verification algorithm in an ellipse curve cryptosystem to perform signature operation on electronic information, and embeds the signature information in a stamp frame or an interior position of a stamp electronic seal template in a digital watermark form to perform electronic signature on appointed electronic documents; and a verification party utilizes the digital signature verification algorithm in the ellipse curve cryptosystem to verify the information of the electronic signature, wherein the digital signature algorithm and the verification algorithm in the ellipse curve cryptosystem are based on an international standard ECDSA method; and twice dot product operation of the prior signature verification algorithm is changed into once dot product operation by utilizing the deformation of a signature equation of the digital signature verification algorithm in the ellipse curve cryptosystem.

Description

technical field [0001] The invention relates to an electronic signature authentication technology, in particular to an electronic signature authentication method based on an elliptic curve signature algorithm. Background technique [0002] Seal technology is a traditional technology in China, which can be traced back to the ancient seals of the Warring States Period, which is a general name for pre-Qin seals. Many documents need to be signed or sealed by hand, especially in written contracts and official documents, they must be signed and sealed by the parties or their responsible persons, so that others can identify who signed the document, indicating the person or unit that signed or sealed Recognition of the content of the document can only legally recognize the validity of the document. [0003] With the development of computers, the Internet and information technology, many traditional paper documents and transaction information have become electronic information, and ...

AI Technical Summary

Problems solved by technology

[0013] 1. It adopts the PKI technology based on RSA1024 bits, and the corresponding digital signature length can reach 1024 bits. If the hexadecimal storage method is adopted, there are also 256 bits. Such long signature information can be stored and verified. Very troublesome, and the speed of signature verification is also very slow;

[0014] 2. For a small number of users, the electronic signature system based on digital certificates is still feasible. In the case of an extremely large number of users, its processing speed and efficiency will be very slow
