Embodiment Construction

[0060] Realization of the hardware system in the electronic signature system of the present invention

[0061] The hardware system scheme of the signature system based on the ECC elliptic curve algorithm as an example is shown in Figure 8, which includes the following core functional modules:

[0062] 1. FPGA module: it mainly completes the four main operations of ECC-based digital signature, signature verification, multipoint operation and key pair generation;

[0063] 2. PROM module: mainly configure the FPGA module after power-on;

[0064] 3. FLASH module: mainly used to store private key data, stamp data (such as images in GIF format) and certificates issued by the CA center;

[0065] 4. USB2.0 module (embedded 8051 core): The reason why we choose the USB2.0 chip embedded with 8051 core is to realize the control of USB2.0 conveniently. This module is mainly used to transfer data between the FPGA module and the software of the PC.

[0066] 5. Power conversion chipset: It...

Abstract

The invention provides a method of achieving the electronic digital signature system in the information system safety special technique field. The method with the association of the software and the hardware achieves the electronic digital signature system, wherein the calculation of all the digital signatures and all the signature checks is made in the hardware printing circuit board and the application-specific integrated circuit. The method enhances the safety of the electronic digital system.

Description

technical field [0001] The invention belongs to the special technical field of information system security, and in particular provides a method for realizing an electronic digital signature system. Background technique [0002] The electronic digital signature system is a high-tech that appears along with the construction of information technology. The electronic digital signature system is mainly used to solve the problem of signing and sealing electronic documents. It is used to identify the identity of the signer of the electronic document, ensure the integrity of the document, and ensure the authenticity, reliability and non-repudiation of the document. [0003] Electronic digital signature is not just a digital image of the commonly used written signature and seal. In the electronic digital signature system, the integrity, authenticity, reliability and non-repudiation of the signature are bound together with the electronic document in the form of an electronic code.
