Embodiment 1

[0047] see image 3 , the specific process of the present invention's digital signature method for large amounts of data is:

[0048] 1. Data transmission

[0049] The client sends the business data, that is, the data information that needs to be digitally signed, and the parameter information required to operate the current business to the server in the form of a stream:

[0050] 11. Put the business parameter information in the HTTP request header;

[0051] 12. Place the business data to be signed in the HTTP request body;

[0052] 2. The message analysis module performs data analysis

[0053] 21. After the server receives the HTTP request, it sends the data stream to the message analysis module to analyze the data;

[0054] 22. Analyze the data flow sent by the client through the message analysis module, and restore the entire data flow to business data and business parameters. During the processing, the integrity of the business data flow is not destroyed, and the busine...

Embodiment 2

[0068] Example 2: Invoking a service via an HTTP request

[0069] The signature server provides the signature service to the client in the form of HTTP service, and the client needs to organize corresponding parameter information when signing a very large data file. Users must store the parameter information in the HTTP request header according to the agreement, and store the business data to be signed in the HTTP body.

Embodiment 3

[0070] Example 3: Calling the service through the client API

[0071] The provided client API interface is integrated into the client software system, and the client provides corresponding parameter information to the interface function by calling the corresponding interface, and the interface function returns the processing result to the client software system.

Abstract

The invention relates to a digital signature method for mass data and belongs to the fields of computer information transmission and safety. The digital signature method comprises that: data is transmitted, a message analysis module performs data analysis, an operation module in a stream mode performs data operation, and a data analysis module performs data analysis. The method is a technical scheme applied to mass data signature based on the characteristics of data transmission, a method of transmitting by data streams and operating by the data streams is implemented therein, and parallel receiving, repeated operation and parallel forwarding are performed. The digital signature method has the advantages that: the problem that vast data cannot adapt to digital signature; and because the data streams are used in the whole process, a signature server does not store mass signature data in a memory so as to improve the processing capacity of the server.

Description

technical field [0001] The invention relates to the fields of computer information transmission and security, in particular to a digital signature method for large data volumes. Background technique [0002] Information security is an important part of the national economy and social informatization, and information security is also an important factor related to the rapid development of e-commerce. Although many control technologies to protect the security of e-commerce have appeared at present, such as digital signature is a typical application, but it is limited to the limitation that it can only handle small data, so it is not widely used so far. [0003] Data stream (data stream) is a concept originally used in the field of communication, which represents a digitally encoded signal sequence of information used in transmission. However, the concept of data flow mentioned in the present invention is different from this. He defines a data stream as "a sequence of data th...
