Embodiment 1

[0095] see Figure 4 , Embodiment 1 of the present invention provides a method for realizing an electronic signature of an electronic invoice, which includes the following steps:

[0096] First of all, the tax bureau needs to make invoice templates suitable for different purposes, and use its own digital certificate and electronic seal to generate an electronic signature of the tax bureau on the invoice template, indicating that the invoice template is certified by the tax bureau; then the enterprise purchases it from the tax bureau The corresponding and certified electronic invoice template, when a consumer purchases the product, fills in the corresponding product information into the invoice template to generate an electronic invoice; finally, the enterprise needs to use its own digital certificate and electronic seal to generate the enterprise's electronic invoice on the electronic invoice. Signature, so that the entire electronic invoice double-signature business process i...

[0099] see Figure 5 , Embodiment 2 of the present invention provides a method for realizing an electronic signature of an electronic invoice, which includes the following steps:

[0100] Step S110, the step of tax bureau signature: generating the tax bureau electronic signature of the tax bureau on the template of the electronic invoice.

[0101] The tax bureau's electronic signature is generated by the tax bureau's electronic seal, specifically, it is encrypted by using an asymmetric encryption algorithm. The asymmetric encryption algorithm has a public key + a private key. The tax bureau uses the private key in the electronic seal (stored in the electronic seal in the form of a certificate) to calculate the summary information based on the template data, and encrypts the summary information to generate the tax bureau electronic certificate.
