Embodiment Construction

[0018] Using the electronic label as the electronic storage medium, the specific implementation method of the present invention is described in anticipation of its application in the anti-counterfeiting of large-scale assembly line products such as alcohol, tobacco, and medicine, as figure 2 shown.

[0019] When initializing, the electronic tag only has the chip's unique identification information TID, and the signature object is the TID, that is, m=TID. The electronic label in the production and circulation link is written into the unique code EPC of the product and the AD of the sales destination, m n =EPC||AD||TID, where the symbol || represents the concatenation of bit strings.

[0020] The digital signature algorithm is selected as the ECDSA signature algorithm, and the signature length is about 384 bits. The parameters (E, p, q, P, G) of the signature algorithm are suggested as follows:

[0021] E: y 2 =x 3 +ax+b, where

[0022] a=-3

[0023] b=6723678989789545453...

Abstract

The invention relates to a digital signature method capable of being implemented on a flow line, comprising the following steps of: generating and storing digital signature in an initialization link; rapidly modifying the digital signature in production and circulation links; and verifying the digital signature in a verification link. By distributing different private information in the links of initialization, production and circulation and executing different algorithms of online / offline signature, the digital signature method provided by the invention benefits the achievement of the purpose of rapidly signing on the flow line in the production and circulation links, and the solution to the problem that digital signature is difficult to implement on the flow line as a result of the efficiency of the digital signature in the prior art.

Description

technical field [0001] The invention relates to the field of information security. In particular, the present invention relates to a digital signature method that can be implemented on a pipeline. Background technique [0002] Digital signature is a basic information security technology, which has important applications in identity authentication, data integrity, non-repudiation, and anonymity, especially in key distribution, authentication, e-commerce, and e-government in network security communications. plays an important role in the system. Digital signature is an important tool for authentication. [0003] The generation and verification of digital signatures require the signer's signature private key and verification public key. The signer's private signing key is known only to the signer. The verification public key of the signer is public. The generation of a digital signature requires the use of the signer's signature private key and the signed digital content. ...
