Embodiment 1

[0039] A method for providing partial credible content for a webpage provided by a preferred embodiment of the present invention includes the following steps:

[0040] Step 1: extract the HTML content to be verified;

[0041] Step 2: Extract the certificate content, if the certificate is an address, download the certificate content, if the certificate is Base64 encoded content, decode the certificate;

[0042] Step 3: Use the root certificate to verify the legitimacy of the certificate. If the verification is successful, continue to the next step. If the verification fails, an error will be prompted and the end will be completed;

[0043] Step 4: Extract signature digest;

[0044] Step 5: Use the VerifyData method of RSA to verify the HTML content of step 1 and the signature digest of step 4;

[0045] Step 6: Display the result in the "authentication information box" according to the verification result in step 5. If the verification is successful, the certificate attribute wi...

Abstract

The invention discloses a method for providing local credible content for a webpage, and belongs to the Information technology field. In the HTML file, a certificate and an abstract are added to content needing to be authenticated; the Browser extracts a public key from a certificate, and performs a Signature verification operation in a display process. If the verification is successful, a publisher is displayed, attributes such as an issuing mechanism and the like are transmitted to the HTML page; A user can preliminarily determine the source of the segment of content through the HTML page, the credibility of the information is preliminarily determined, and the problems that in the prior art, the safety and traceability of webpage content in the network space cannot be guaranteed, and secondary creation cannot be carried out while the file credibility is guaranteed are solved.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a method for providing partial credible content for a web page. Background technique [0002] The RSA algorithm, also known as the RSA public key cryptosystem, uses different encryption keys and decryption keys. Usually, a pair of RSA keys is first generated, one of which is a secret key, which is kept by the user; the other is a public key. The key can be disclosed to the public, and even registered in the network server. It is a cryptographic system that "deriving the decryption key from the known encryption key is computationally infeasible". It is the first cryptosystem that can be used for both encryption and encryption. The algorithm of digital signature is also easy to understand and operate. The RSA algorithm is the most widely studied public key algorithm. It has experienced various attacks and gradually accepted by people in the past 30 years since it was proposed. ...
