Problems solved by technology

In this method, due to the limited content of the data message, only the signature hash value can be pushed to complete the digital signature. The terminal side cannot verify the original text of the signature content, and cannot verify the source of the digital signature request. There is a risk of third-party attacks.

Abstract

The invention relates to a digital signature method, a digital signature system, an intelligent terminal and a service system. According to the digital signature method, on the basis of generating a digital signature information trusted graphics code by the service system, digital signature is completed after the trusted graphics code is scanned and verified through an intelligent terminal (such as a mobile phone), the related signature information is transmitted to the service system, the service system feeds back a result to a personal computer browser, and the digital signature process is completed. The process does not need to access the secret key of the personal computer through a control, out-of-band interaction among the personal computer, the intelligent terminal and the service system is built through the trusted graphics code, the digital signature is completed, the safety experience of the user is enhanced, the digital certificate use complexity by the user is reduced, and a safe, novel and creative digital certificate application by using the service system to quickly deploy the digital signature technology to realize integrity and authenticity of the data.

Description

technical field [0001] The present invention relates to Internet security technology, more specifically, to a digital signature method and system, an intelligent terminal and a business system thereof. Background technique [0002] Digital signature is a solution to solve data integrity and source traceability. It ensures the user's trusted identity by applying for a digital certificate from a trusted third-party organization through the user's pre-generated key. The hash value generated by the column algorithm forms a digital signature. The receiver uses the sender's public key to verify and decrypt the hash value, and hashes the original text through the same hash algorithm, and compares the two hash values ​​to confirm the validity of the digital signature. [0003] At present, on personal computers, Internet applications mainly use WEB to access pages, and the digital signature of Internet applications needs to be operated through a browser. As the interactive entrance ...
