A data preparation management method based on task mechanism

Abstract

The invention discloses a data preparation and management method based on a task mechanism. The original card making data and key data are combined, and the dispersion factor is involved in the key data preparation process, which avoids the single key data being directly used as an IC card or The potential safety hazard of the chip key has high practicability; by specifying the key, using different and multiple distribution factors, the key is distributed and calculated layer by layer, and several pieces of dispersed key data and key data are obtained. The preparation process is interlocking and rigorous, with high security; the introduction of the task mechanism, the establishment of the card production task, the determination of the task start time, the system can start or suspend the card production task, the background service according to the card production Tasks perform corresponding operations to meet the different needs of different application systems for key data preparation, and have wide adaptability. Improve the security of the key data preparation process and meet the user's large-scale and centralized issuance operation requirements for IC cards or chips.

Description

technical field [0001] The invention belongs to the technical field of information security encryption, and relates to a data preparation management method based on a task mechanism. Background technique [0002] Cryptography technology is the basic technology of information security, and the key is the basis of secure application of cryptography technology and the core element of information security. With the rapid and comprehensive development of my country's information industry, the key management system based on IC card business has also entered the comprehensive construction stage, and the key data preparation and management in the system are facing more and more stringent technical requirements. [0003] The current traditional IC card-based business key management system mainly uses its own key management mechanism to generate target card making data for IC cards, and completes the issuance of IC card target card making data. [0004] In the above process, the targ...

Problems solved by technology

[0004] In the above process, the generation process of target card making data is concentrated in the key management system. In addition to completing the key life cycle management function, the key management system also needs to complete the target The card making data preparation work adds management functions other than the key management function to the key management system, which increases the management burden of the key management system

At the same time, the system target card data generation process is single, and the key data is not managed based on the task mechanism. As a result, the target card data key data generation process is too simple, which does not satisfy the user's mass and centralized issuance of IC cards or chips. Operational requirements, there are certain security risks
