Electronic Signature Token Data Transmission Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for transmitting signed data using electronic signature tokens are inefficient, resulting in prolonged transmission times, which necessitates a reduction in this process.
Innovation Solution
The method involves obtaining a signing request data packet, signing the data, and then employing a preset transmitting strategy to divide the signed data into segments for transmission at two distinct times: before and after user confirmation, with the first segment being encrypted and the second segment transmitted after confirmation, utilizing an idle transmission line to enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the signed data is transmitted in a single batch after user confirmation, then the transmission process is simple, but the transmission time is prolonged (over 1 second)
Solution Approach 1:
The signed data is divided into two segments: first data (transmitted before user confirmation) and second data (transmitted after user confirmation). This segmentation allows the transmission to overlap with the user confirmation process, reducing the total transmission time from over 1 second to 100-200 milliseconds.
2Productivity
If the signed data is transmitted before user confirmation, then the transmission time is reduced, but the transmission line utilization is insufficient
Solution Approach 1:
The first data is transmitted in advance before the user confirmation is received. This preliminary action utilizes the transmission line during the confirmation period, improving overall utilization without extending the total transmission time, as the second data is transmitted immediately after confirmation.
3Reliability
If the first data is encrypted before transmission, then the security is improved, but the processing time increases
Solution Approach 1:
The encryption of the first data is performed in advance before transmission. This preliminary encryption action ensures data security while allowing the encrypted data to be transmitted immediately, minimizing the impact on overall processing time.

AI summary
Provided are a signature data transmission method and electronic signature token, the method comprising: an electronic signature token acquires a signature request data packet comprising data to be signed; signing the data to be signed to obtain signed data; acquiring a first preset transmission policy, and acquiring first data to be transmitted according to part of the signed data and the first transmission policy, and then transmitting once or multiple times the first data to be transmitted; after obtaining the signature request data packet, extracting and outputting the key information of the data to be signed; acquiring an acknowledgement instruction of the outputted key information of the data to be signed; after obtaining the acknowledgement instruction, acquiring a second preset transmission policy, and acquiring, according to the remaining part of the signed data and the second transmission policy, second data to be transmitted, and then transmitting once or multiple times the second data to be transmitted.
